Highways 30 through 39

M-30 | US-31 | M-32 | US-33 | M-33 | M-34 | M-35 | M-36 | M-37 | M-38 | M-39 | Jump to Bottom

• US-31 Freeway in Berrien County
• US-31 Freeway in Ottawa County
• US-31: Traverse City Bypass
• US-31: Petoskey Bypass

• (Mar 28) - Several small realignments and relocations in western Charlevoix Co straighten out the route of US-31. Most of the former alignments—those portions not obliterated completely—are turned back to local control, including Old Orchard Tr and Schmidt Rd, Ferry Rd easterly to Beatty Rd and Beatty northerly to US-31, Cedarview Dr and Clipperview Dr north of Cedarview, and others.
• (June 30) - A new direct Grand River crossing from Grand Haven northerly into Ferrysburg via an electrically-operated swing bridge was completed on November 11, 1924, replacing an old hand-operated interurban bridge to the east. On this date, that bridge and its approach roadways were incorporated into the state trunkline system and the former route is officially cancelled.
• (Aug 20) - A slight realignment occurs in Muskegon Heights. Entering the city from the southeast via Merriam Ave, the route formerly continued via Merriam to Summit Ave, then westery via Summit for one block before turning northerly along Peck St toward downtown Muskegon. Now, US-31 curves westerly from Merriam Ave onto Lincoln Ave for two blocks, then turns northerly via Peck St. The former route along Merriam from Lincoln to Summit and along Summit from Merriam to Peck is turned back to local control.

• (July 5) - The stair-stepping route of US-31 from the north limits of Saugatuck northeasterly for 2.2 miles is turned back to control when a new, more directly 1.4-mile long alignment is assumed into the state trunkline system. Construction on the new alignment, however, may not have been complete until 1930.
• (Aug 19) - Since originally debuting in 1926, US-31 entered Michigan from Indiana and continued northerly into downtown Niles via 3rd St. On this date, the 3rd St route is transferred to local control and the parallel 11th St alignment is determined as a state trunkline highway and becomes the new route of US-31.
• (Aug 19) - The portion of US-31 from Oden northerly thorugh Alanson to south of Brutus in Emmet Co via Milton Rd/Milton St is turned back to local control when the present-day route is officially established as a state trunkline route. The new route is also 1/10th mile shorter than the former. Construction on the new route, however, is likely not complete until the next year.

• 1930 (Nov 22) - The route along present-day M-63 from Paw Paw Ave to Eaman Rd north of Benton Harbor is determined. From the cnr of Paw Paw Ave & present-day M-63 southerly into Benton Harbor, US-31 will follow Paw Paw Ave itself, although that roadway is never officially added to the trunkline system, only being "marked and maintained" as a temporary link for several decades.
• 1930 (Dec 23) - The route, via present-day M-63, from Eaman Rd northerly to the Berrien/Van Buren Co line is determined.
• 1931 (Oct 23) - From the Berrien/Van Buren Co line northerly to existing US-31 (present-day M-140) south of South Haven is officially assumed into the state trunkline system. It is assumed the entire highway from Paw Paw Ave north of Benton Harbor to South Haven opens around this time.

• (Oct 29) - An easterly bypass of North Muskegon is also officially determined as a state trunkline in late 1932 and likely opens to traffic at the same time. Beginning at the eastern jct of US-31 & M-20 (cnr Whitehall Rd & Holton Rd-Lake Ave) the new route continues northwesterly back to the original alignment of US-31 at Witham Dr. The former route along Lake Ave and Center St to Ruddiman Ave retains the M-20 designation while the portion along Center north of Ruddiman and along Witham Dr northerly to the new bypass is turned back to local control.
• (Oct 29) - A new route for US-31 entering Charlevoix from the southwest is established along its present-day route from Barnard Rd easterly, then curving northerly into the city to Carpenter Ave where it then continues northerly via Bridge St to M-66 at Garfield Ave. There, US-31 supplants the M-66 designation northerly for five blocks to Antrim St and the former route of US-31. The former route along Barnard Rd from US-31 northeasterly to Carpenter Ave is turned back to county control but will later be removed when the airport runways are built across it in later years. The former route in the city along Norwood Rd northerly to Sheridan St, then northerly via Sheridan to Antrim St and easterly via Antrim to Bridge St is turned back to city control.
• (Oct 29) - A more direct routing for US-31 from Levering to Carp Lake is officially assumed into the state trunkline system on this date, however sources indicate construction on the 4.2 mile route is not complete until 1933, though traffic may have been allowed to use the unpaved alignment starting this year. The former route via Levering Rd westerly from US-31 to Reed Rd, northerly via Reed to Gil Rd and easterly along Gill to the new alignment of US-31 is turned back to local control.

• (July 12) - A new, more direct alongment for US-31 is completed along the route of present-day Oceana Dr between Hayes and Water Rds, halfway between New Era and Shelby. The former route along Hayes Rd and Water Rd is turned back to local control on this date.
• (July 12) - Also on July 12, the new alignment of US-31 from northeast of Bay View northeasterly through Conway and Oden to south of Alanson is officially determined as a state trunkline route and the former route (that portion which does not lie underneath the new alignment), mostly Hiawatha Tr from M-131 (present-day M-119) to Conway, is turned back to local control. The new alignment was completed, however, during 1930 and it is unclear why the jurisdictional transfer takes place three years later.
• The Manistee River bascule (draw) bridge in downtown Manistee is completed and opened to traffic. The bridge remains in service to the present-day.

• (Aug 30, Sept 27) - On August 30, a new trunkline route for US-12/US-31 through downtown Benton Harbor is officially added to the state trunkline system along Main St from Water St easterly to Fair Ave, then northerly via Fair Ave to the existing route along Territorial Rd. The former trunkline route northerly from Main St via Water St and easterly along Territorial to Fair remained in system for nearly a month before being turned back to local control on September 27.
• (Aug 30) - A second new route determination for part of US-31, this one an eastern bypass of Saugatuck in Allegan Co. The former route through downtown Saugatuck via Lake, Gulver, Butler, Francis and Holland Sts is turned back to local control. Sources seem to indicate, however, that construction on the new bypass may not be complete until 1938.
• (Aug 30) - Several sharp turns in the route of US-31 in Mason Co are replaced by a new, sweeping alignment for the highway southeast of Ludington. The former route along Meyers, Hesslund and Lenz Rds is turned back to local control.
• (Aug 30) - The former route of US-31/M-72 in the East Bay area east of Traverse City via Holiday and 5 Mile Rds, bypassed by a new alignment completed in 1936, is turned back to local control.
• (Aug 30, Dec 29) - The final segments of the new alignment of US-2 along the Lake Michigan shore in Mackinac Co between Brevort and St Ignace are officially established as state trunkline segments on Dec 29 and likely open about the same time, however the former route of US-2 from Brevort easterly via Worth Rd to Moran, then southeasterly via Tahquamenon Tr (present-day M-123) to Rogers Park is turned back to local control on Aug 30! While it could be assumed that either of these dates is when US-31 is removed from the U.P. and truncated back to the State Highway Ferry Docks in Mackinaw City, official MSHD maps will continue to show US-2 and US-31 running northerly from St Ignace concurrently to Rogers Park through 1939, where the US-31 designation appears to simply end while US-2 continues northerly toward Sault Ste Marie. One could speculate the state may have had ideas on extending US-31 from that point, possibly northerly along the Tahquamenon Trail (present-day M-123), but no other evidence has been found to date to support that speculation. Additionally, official maps show the spur from US-2 in St Ignace to the "new" State Highway docks as also being M-122 from 1936 on. In any event, US-31 is truncated back to Mackinaw City by 1939 for certain.
• (Dec 29) - A brand new route for US-31, partially on new alignment, partially using existing roadway, is officially assumed into the state trunkline system from 1.4 miles northeast of Saugatuck (at 64th St) northeasterly via Blue Star Hwy to 58th St, then northerly via 58th St to the Allegan/Ottawa Co line, continuing northeasterly via Michigan St to the cnr of River Ave & State St in Holland (although the portion of Michigan from 33nd St to 28th St had been added on December 9 of the previous year). This new route is now signed as the mainline US-31 between Saugatuck and Holland. The former route via 64th St northerly to 32nd St, then easterly for two miles via 32nd to Lugers Rd, northerly on Lugers to South Shore Dr, easterly via South Shore Dr and 17th St to River Ave in Holland is redesignated as US-31A. This route, however, may have been open more than a year before it was officially determined.

• The Muskegon bypass, consisting of Getty Ave and Marquette Ave and formerly designated as US-31A in 1932, is redesignated as part of mainline US-31. The former route of US-31 through downtown Muskegon becomes US-31A.
• (Nov 12) - The route of US-31 between Shelby and Hart in central Oceana Co is relocated onto a more direct alignment, along with a great deal of cut-and-fill through the area hills. The former route departed modern-day Oceana Dr two miles north of downtown Oceana and followed Water Rd northerly to Russell St (Polk Rd) on the southern limit of Hart. The new route continues northerly from the Water Rd turnoff via present-day Oceana Dr to Russell St-Polk Rd, turning westerly via Russell back to the former route at Water Rd-State St in Hart.
• The concurrent designation with M-42 between Chum's Corner (two miles east of Grawn) and Traverse City is redesignated as M-37. This reflects M-37's extension into Traverse City along what had been part of M-42.
• (Nov 12) - Also on November 12, a realignment on the west side of Petoskey relocates US-31 onto its present-day route from the cnr of Charlevoix Ave & Spring St northeasterly to the cnr of Mitchell & Liberty Sts, shaving more than 1/10th mile from the route. The former route via Charlevoix Ave easterly from Spring to Connable Ave, northerly one block on Connable to Jackson St, easterly two blocks on Jackson to Liberty and northerly via Liberty St back to Mitchell St is turned back to local control.
• The concurrent designation with US-2 is removed between St Ignace and the former junction of US-2 and US-31 at Rogers Park, 9 miles north of St Ignace (the present-day junction of Old M-123 and Mackinac Trail/H-63). US-31 now ends with US-23 and US-27 at the State Ferry Docks in Mackinaw City.

• The new relocation of US-31 between Charlevoix and Bay Shore, established in early 1942, is completed and opened to traffic. While the new alignment is 1/10th mile longer, the former route is a windy, narrow road with many turns, also twice crossing the C&O Railway line.
• (Oct 27) - The new Blossomland Bridge, a bascule span, opens across the St Joseph River in downtown St Joseph, replacing an older structure on State St just downstream. The bridge sits on a northerly extension of Main St in St Joseph. One block south of the new Blossomland Bridge, US-31 continues to turn easterly concurrently with US-12 into dowtown Benton Harbor, however, as a new highway connecting the new bridge to existing US-31 north of the 'Twin Cities' is not complete. For the time being, traffic from the bridge detours west via Oak St to the now-severed N State St (present-day Upton Dr).
• (Nov 7) - The route of US-31 in use since it was completed in 1930 from Bay Shore easterly for 3.4 miles to east of Townsend Rd in southwestern Emmet Co is officially established as a state trunkline while the former route via Church St and "Old US-31," which has not been posted as part of US-31 since 1930, is similarly transferred to local control. It is assumed these jurisdictional transfers are to clean up unfinished business from twenty years earlier.
• (Nov 10) - The southwesterly approach into Traverse City for US-31/M-37 is completely revamped. Starting two miles north of Chums Corners, the highway formerly followed McCrae Hill Rd, a roadway since obliterated from present-day US-31/M-37 northeasterly to the 90-degree curve in South Airport Rd, then South Airport northerly to Veterans Dr (formerly Rennie St), Veterans (Rennie) northerly into Traverse City to 14th St, 14th easterly to Union St and Union northerly to jct M-22/M-72 at Front St downtown. Most of this route is turned back to local control on this date when the newly-completed route following present-day US-31/M-37 is established as a state trunkline from the southern intersection with McCrae Hill Rd northerly to 14th St in Traverse City. Oddly, this leaves a gap in the established route from the cnr of Division St & 14th St and Front St & Union St, although sources indicate the route of US-31/M-37 is likely signed northerly from 14th St along Division St to M-22/M-72/Front St, then easterly along M-22/M-72/Front St back to the former route at Union St.

• The concurrent US-33 designation with US-12/US-31 in downtown St Joseph is scaled back nine blocks to end at the jct of US-12/US-31/US-33 (Niles Ave & Main St), as it had prior to the War.
• A new alignment for the Muskegon bypass opens following Hile Rd easterly from US-31/Grand Haven Rd to Harvey St, then northerly along Harvey to north of Marquette Ave where the route arcs back westerly to the existing US-31 route. The former route along Getty Ave and Marquette Ave is turned back to local control. BUS US-31 at Muskegon is extended slightly at each end to meet with the new mainline US-31.
• (Nov 30) - A new alignment for US-31 is completed and opened to traffic from M-21/Chicago Dr at Holland northwesterly for 9.6 miles to West Olive where it rejoins its former route. The highway is built as a two-lane facility on a four-lane, limited access alignment. The former route remains an unsigned state trunkline for more than a year.

• (July 2) - A minor realignment in New Era shaves 1/10th mile from the length of US-31. When the new "First St extension" is assumed as a state trunkline route on this date, the former route via Ray and 3rd Sts is turned back to local control.
• (July 19) - A new 3/10th mile long southerly approach to the Manistee River bascule bridge is officially determined as a state trunkline via present-day Cypress St from River St at the southern end of the bridge southerly to First St where it rejoins the existing route. The former route westerly from Cypress along River St, southerly via Division St and easterly via First to Cypress is transferred to local control.

• (Aug 3) - While the short portion of the "Holland Bypass" from M-21/Chicago Dr southerly to 16th St was determined as a state trunkline on November 3, 1950, the remainder of the bypass around the east and southern sides of the city are determined on this date and the whole route likely opens at the same time. The fomer route through downtown via Chicago Dr, 8th St, River Ave, Michigan St and Washington Ave becomes BUS US-31.
• (Aug 3) - Also on this date, a new 4.99-mile long bypass (of sorts) of Pentwater is assumed into the state trunkline system and opened to traffic. The new alignment runs along present-day Oceana Dr between Monroe and Washington Rds and shaves three miles from the route of US-31 through downtown Pentwater, which is now redesignated as BUS US-31.
• (Nov 18) - The US-31 realignment project south of the Manistee River bascule (draw) bridge in Mansitee begun in 1951 with the opening of the first phase is completed with a rerouting/realignment of the highway through the remainder of the city. From First St, US-31 now continues southerly via Cypress Ave to 8th St where it bends southeasterly via a new highway alignment along present-day Manistee Hwy before merging back into the existing route near the present-day intersection with Stronach Rd. The former stair-stepping route of US-31 is turned back to local control on this day. —Thanks to John McDowell for the heads-up!

• (June 17) - A new, more direct highway alignment is completed and opens to traffic from the center of Grand Haven Twp northerly via its present-day alignment and Beacon Blvd to Jackson St in the middle of the city of Grand Haven. The former route of US-31 from Ferris St northerly along 168th and Beechtree Sts, westerly via Fulton St and northerly again via 7th St to Jackson St is turned back to local control.
• (June 24) - The remaining portion of the former route of US-31/M-37 along McCrae Hill Rd southwest of Traverse City, from Silver Pines Rd northerly to US-31/M-37, is turned back to local control. The rest of this former route of US-31/M-37 had been transferred in 1949 and its is unclear at present why this portion was retained for eight additional years.
• (Oct 21) - One week prior to the opening of the new Mackinac Straits Bridge between Mackinaw City and Saint Ignace, the freeway approach highway is officially assumed into the state trunkline system from US-31/Nicolet Ave northerly to the foot of the new bridge. It is unclear whether the freeway opens to traffic as far as the Jamet St interchange for this next week or if traffic is only allowed on as of the bridge's opening on November 1st, however it can be assumed US-31 remains posted on its existing route to the State Highway Ferry Docks until that time when it is transferred to the freeway approach on the 1st, terminating with US-23 at the southern end of the bridge. Officially, though, the former route of US-31 along Nicolet Ave, the "Old 31" cut-across and along Huron st from the US-23/US-27 jct northerly to the ferry docks is transferred to local control on this date.
• (Nov 25) - A new easterly bypass of Hart is officially assumed into the state trunkline system from Russell St-Polk Rd on the southern city limit northerly to N State St north of the city and likely opens to traffic at this time as well. The former route of US-31 through Hart via Russell St and State St is turned back to local control.

• (July 24, Oct 22) - The first portion of US-31 freeway is completed from the Grand River in Ferrysburg to just north of the US-16 & BUS US-31 jct southeast of Muskegon. The freeway is built parallel to Old US-31/Grand Haven Rd within a mile to the east, curving to the east north of Sternberg Rd and merging into the 1950 Harvey St bypass at Airport Rd just north of Airline Rd. The portion of the freeway in Ottawa Co is determined on July 24 (with the former route along 174th Ave transferred to local control) while the portion in Muskegon Co on October 22 (again, with the former route via Grand Haven Rd turned back to local control). The entire freeway likely opens in October.
• (Oct 22) - In a major trunkline realignment project, a brand-new limited-access expressway route into downtown Muskegon from the southeast side is completed. The new Seaway Drive route, initially known as the "Norton-Glade Expressway," named for two of the existing streets the highway runs parallel to, is given the US-16/BUS US-31 designation and bypasses Muskegon Heights en route into downtown Muskegon where the route splits into two, parallel one-way streets, Muskegon Ave (nbd) and Webster Ave (sbd), to M-46/First St. The former BUS US-31 route along Merriam and Peck Sts is returned to local control.

• (June 12) - A new six-lane bascule (draw) bridge is completed spanning the Grand River between Grand Haven and Ferrysburg, replacing the 1924 swing bridge. The new structure consists of nine spans, is 750 feet long, and clears the river channel by about 25 feet.
• (Nov 25) - Two miles of new freeway are completed and opened to traffic from the Nicolet St interchange (present-day Exit 337) south of Mackinaw City southerly and a new freeway connection is made with I-75 three miles south of Mackinaw City. From Mackinaw Hwy, US-31 now turns northeasterly for a short distance and merges into the new freeway to continue northerly with I-75 to end at the foot of the Mackinac Bridge. (The future direct alignment from the corner of Mackinaw Hwy and the new US-31 ramps southwesterly to Carp Lake would not open for more than two more years.) The former route of US-31 along Mackinaw Hwy from the Nicolet St interchange southerly to the ramps from present-day Exit 336 is turned back to local control.

• The 1950 "Harvey St bypass" route along the east side of the City of Muskegon is converted from a two-lane surface route to a fully-controlled access freeway from the northern end of the completed freeway (1959) near Airport Rd southeast of the city northerly either atop (Airport-Laketon) or immediately adjacent to (Laketon-Lawrence) the Harvey St route to Lawrence Ave approximately 1/4 mile north of the M-46/Apple Ave interchange, where it temporarily merges back down into the two-lane Harvey St alignment. (The portion of this route from Laketon Ave northerly to Lawrence Ave is determined as a trunkline and the former route via Harvey St is turned back to local control on October 12, 1961, however sources indicate it was likely complete and open to traffic in 1960.)
• The US-33 designation is also extended along US-31 northerly from St Joseph for about 10 miles, in preparation for the realignment of US-31 via the new freeway under construction northerly from I-94.

• While not yet officially determined as a state trunkline routing (that would happen the next year), the first seven-mile segment of the I-96/US-31 freeway is completed and open from I-94 to US-31/US-33/Hagar Shore Rd near the Berrien/Van Buren Co line. The US-31 designation is routed northerly from Scottdale via the ex-M-139 to I-94, then northeasterly with I-94 to the new freeway (at present-day Exit 34) and then northerly to the end of the freeway at Hagar Shores Rd (at present-day Exit 7). The former route of US-31 through St Joseph between Scottdale and Hagar Shore Rd becomes solely US-33.
• In the Muskegon area, with the decommissioning of US-16 in Michigan, the routing of US-16/BUS US-31 into downtown Muskegon becomes BS I-196/BUS US-31.
• (Sept 29, Nov 15) - On Sept 29, the new two-lane, controlled-access realignment of US-31 from Carp Lake northeasterly to Mackinaw Hwy at the new I-75 interchange south of Mackinaw City officially becomes a state trunkline and likely opens at the same time. The former route via Mackinaw Hwy and Paradise Tr is transferred to local control. On Nov 15, the short portion of the US-31 alignment east of Mackinaw Hwy to the I-75 interchange is officially determined as a state trunkline (the same day all of I-75 in Cheboygan Co is similarly determined), but this is likely just an official date of transfer, as I-75 and the US-31 interchange had been complete here for two years.

• (Jan 20) - A new northside limited-access connector is completed and certified as a state trunkline on this date from the present-day intersection of Skyline Dr (Moses J Jones Pkwy) & Bayou Ave on the north side of Muskegon northerly a short distance to a complex new intersection with M-20 (present-day M-120) before turning easterly to a new tri-level interchange at the US-31 freeway northeast of the city. With the new highway opening, the BUS US-31 temporary routing via M-20 north across Veterans Memorial Causeway into North Muskegon then northeasterly to US-31 is removed and transferred to its new permanent route. The following segments of the former route of US-31 not subsumed under new highway alignments include:
  • Ottawa St from Bayou Ave northerly to the cul-de-sac near the BUS US-31 & M-20 (present-day M-120) junction;
  • Access Hwy from west of Getty St easterly to the US-31 freeway at Broadmoor St;
  • Harvey St from north of Brusse Ave southerly to Marcoux Ave near Mercy General Hospital.
• (June 25) - The final piece of the new BUS US-31 loop through Muskegon is completed when Skyline Dr (Moses J Jones Pkwy) is certified as a state trunkline from Bayou Ave southerly to Muskegon Ave (nbd) and Western Ave (sbd), continuing southwesterly through downtown via Muskegon-Webster to M-46/First St, meeting up with the 1959 portion of the new business route. At the same time, the former route of BUS US-31 along First St from Webster Ave to Clay Ave and Clay Ave-Ottawa St from First northeasterly to Bayou Ave is turned back to local control.

• (Apr 16) - An 18.09-mile long northerly extension of the US-31 freeway from just north of the Fruitvale Rd interchange north of Montague northerly to Polk Rd west of Hart is officially determined as a state trunkline highway routing. The freeway is not yet complete at this time, however, and would be opened in two stages, the first of which would come later in the year. Also transferred to state control on this date is Polk Rd itself from the new US-31 freeway interchange easterly to State St and State northerly from Polk to Lincoln St, ostensibly for a new BUS US-31 route once the freeway is completed and is likely not signed in the field at this time.
• Later in 1975, the first stage of the US-31 freeway extension into Oceana Co opens from the northern end of the completed freeway three miles north of Montague to the new M-20 extension at Stoney Lake Rd near New Era, where US-31 temporarily turns easterly via the M-20 extension back to its former alignment. The former US-31 routing via Whitehall Rd in Muskegon Co (north of B-15/B-23/Fruitvale Rd) and OLD US-31/Oceana Dr in Oceana Co becomes an unsigned state trunkline.

• Another new portion of US-31 freeway is completed and opened to traffic from M-20 at New Era northerly to Polk Rd west of Hart. There, US-31 traffic is routed easterly via Polk Rd to the existing US-31. OLD US-31/Oceana Dr from M-20 northerly through Shelby to Polk Rd at Hart becomes an extension of the unsigned state trunkline.
• (Dec 14) - With constrution yet to begin in earnest, a 5.66-mile long extension of the US-31 freeway in Oceana Co from Polk Rd at Hart northerly to just north of the BUS US-31/Monroe Rd interchange southeast of Pentwater is officially determined as a state trunkline. This portion of the freeway would not open for nearly two years.

• The US-31 freeway bypass of Niles is extended northerly from US-12/Pulaski Hwy to Walton Rd northwest of Niles, where US-31 now turns northeasterly via Walton back to its existing route. A new BUS US-31 routing at Niles is then created by cobbling together a variety of different routes: From the US-31 & US-12 interchange, the new BUS US-31 proceeds easterly via US-12 to US-33/11th St, then northerly via 11th St supplanting the US-33 routing into downtown Niles, then westerly via BUS US-12/Main St to Front St (the former route of US-31), then northerly via Front St and the former US-31 to Walton Rd, where it terminates. The former route of US-31 (not assumed into the new BUS US-31 routing) via BUS US-12 (Chicago Rd, Lincoln St/Grant-St Joseph Sts & W Main St) in Niles retains the BUS US-12 designation. —Thanks to Marc Fannin for clarification on this routing!
• A new "spur" business routing debuts as BUS US-31 via Polk Rd and State St into downtown Hart.

• The 1.96-mile long stretch of OLD US-31/Whitehall Rd in northern Muskegon Co from jct BUS US-31 & B-15 north of Montague northerly to the Muskegon/Oceana Co line is turned back to local control.
• (Mar 20) - Two additional segments of OLD US-31/Oceana Dr are transferred to local control on this date: 2-1/2 miles from the north limits of Rothbury to the south limits of New Era and 0.37 miles from the north limits of New Era to M-20.

1. From southern entrance at the Indiana state line northerly to Napier Ave east of Benton Harbor. (24.1 miles)
2. From jct I-94 (at Exit 28) & I-196 northeast of Benton Harbor to the Washington Ave-Blue Star Hwy interchange on the south side of Holland. (47.4 miles)
3. From the Grand River Drawbridge on the border between Grand Haven and Ferrysburg to US-10 east of Ludington. (66 miles)

1. From the northern end of the freeway segment on the south side of Holland to Port Sheldon Rd north of Holland.
2. From Ferris St to Robbins Rd on the south side of Grand Haven.

1. From M-63 at Hagar Shores to the southern jct of BL I-196 at South Haven.
2. From the northern jct of BL I-196 at South Haven to the southern jct of BUS US-31 in Norton Shore. NOTE: With the removal of BUS US-31 at Holland in August 2004, the LMCT no longer runs through downtown Holland. Signage to this effect was finally corrected in 2010.
3. From the northern jct of BUS US-31 at Muskegon to the southern jct of BUS US-31 at Whitehall.
4. From the northern jct of BUS US-31 at Montague to the southern jct of BUS US-31 southeast of Pentwater. NOTE: With route marker signage changes in LMCT-2011, it is unclear whether the official LMCT route still uses BUS US-31 through Pentwater. If attempting to follow the LMCT route, understand there may no longer be LMCT signs through Pentwater.
5. From the northern jct of BUS US-31 northeast of Pentwater to M-22 northeast of Manistee.
6. From the jct of M-22/M-72 & US-31/M-37 in Traverse City to northern terminus south of Mackinaw City.

• US-31 Freeway in Berrien County
• US-31 Freeway in Ottawa County
• US-31: Traverse City Bypass
• US-31: Petoskey Bypass

• M-37/M-96 is routed off Van Buren St and on to Michigan Ave in Battle Creek. Van Buren St is given back to municipal control.
• M-37 also is scaled back for approximately one mile to end at Capitol Ave (jct. US-12A/M-78/M-37/M-96).
• A short, new 4-mile long graded-earth surfaced segment of future M-37 opens from M-55 twenty-one miles west of Cadillac southerly to the Wexford-Lake County line. It is unclear whether this short stub of a highway was signed as M-37 at this time.
• A new alignment of M-37 opens between Brohman and Lilley in northern Newaygo Co, bypassing Bitely and shaving two miles from the route, the former route being turned back to local control.

• Two segments of the Southfield Road Expressway (freeway) open:
  • 3.5 miles from Gildow St (present-day Hubbard Dr) in Dearborn to just north of Joy Rd.
  • 0.5 miles, one-quarter mile on either side of the Plymouth Rd interchange.
• The M-39 designation is extended southerly from I-94 (itself now sans US-12) via Southfield Rd to US-25/Toledo-Dix Hwy.
