US-2 Route MarkerIron County Heritage Route logo

Iron County
Heritage Trail

Western End:   Iron River
Eastern End:   Crystal Falls
Length: 16 miles
Notes: From MDOT: "Located in the southwest corner of Michigan’s beautiful Upper Peninsula, Iron County is steeped in the rich history of two industries that built a state and nation: mining and logging. Rustic mining camps, museums, parks and period houses usher visitors back in time as they travel the 16-mile route and intersecting roadways. It’s the perfect venue to learn what made iron king, an amazing story started some 1.2 billion years ago and entailing the Bronze Age, Industrial Revolution and world conflicts."
  The US-2 Iron County Heritage Route was designated as a Heritage Route in 2000.
  While the officially-designated Historic Heritage Trail is the 16 miles of US-2 from Crystal Falls to Iron River, the "Iron County Heritage Trail" itself is"composed of a 36 mile loop connecting 14 premier sites that provide visitors the opportunity to discover the historic and recreation resources of Iron County." The loop continues south from the Heritage Route's western end in Iron River via M-189, then turns east via CR-424 through Caspian, Gaastra and Alpha, before returning to Crystal Falls via US-2/US-141. Thus, the Iron County Historic Heritage Route is only a portion of the overall Iron County Heritage Trail.

Heritage Trail

Western End: New Buffalo
Eastern End: Downtown Detroit
Length: 209 miles
Notes: While two short segments of US-12 has been previously designated as Historic Heritage Routes, in Saline and Clinton/Clinton Twp, on June 9, 2004 the entire length of US-12 from New Buffalo on the Lake Michigan shore to the eastern terminus of US-12 in downtown Detroit was designated as a Historic Heritage Route in its entirety. And while most of the other Heritage Routes in Michigan have been designated with a descriptive name, this route continues to be known as just the US-12 Heritage Trail.
  US-12 Heritage Route logoFrom MDOT: "US-12 is among the oldest road corridors east of the Mississippi River and accesses some of the most extensive and significant historic, cultural, scenic and recreational resources in Michigan," said Pete Hanses, MDOT's Heritage Route manager. "It begins in downtown Detroit, just blocks from the Detroit River, and extends through southern Michigan to the Michigan/Indiana border south of New Buffalo. It was originally a network of centuries-old trails created by Native Americans. Over the years it has had many names such as Sauk Trail, Chicago Road, and Michigan Avenue."
  Former US-12 Heritage Route logoAlso from MDOT: "Centuries in the making, the US-12 Heritage Trail connects man, animals, commerce, culture, and nature. From its origins as a network of Native American trails, the US-12 Heritage Trail became one of the most important migration routes for settlers into the Michigan territory. The road was paved in 1920 when Ford sold over a million cars and was officially designated as a United States highway in 1926. Today the 212-mile US-12 Heritage Trail stretches from Detroit to New Buffalo, continuing to be the backbone of Southern Michigan and an access point for exploration and discovery. Rich in colorful character, remarkable history and an ever- changing landscape, the US-12 Heritage Trail invites the traveler to journey its winding road, meet its people, explore its places and uncover its hidden treasures."

Center Avenue Heritage Route/
Bay City Historic Route

Western End: Madison Ave in downtown Bay City
Eastern End: Bay City east city limit
Length: 1.5 miles
Notes: From MDOT: "M-25 through Bay City was designated as a Historic Heritage Route. The City of Bay City in conjunction with MDOT nominated the 1.5 miles long portion of M-25 which runs from Madison Avenue to Livingston Avenue. Visible from the road is the Bay County Building, which is on the National Register for Historic Places. The area also contains 48 pre-1900 and 32 1900–1929 structures, which are also on the National Register as part of the Center Avenue Historic District."
  Also from MDOT: "Travel this Heritage Route and you’ll return to an era when lumbering, ship building, agriculture and commerce flourished in the city by the bay. From its picturesque tree-lined streets, to majestic mansions, to a beautifully restored county building and business district, Bay City is a preservationist’s dream. The Center Avenue (M-25) neighborhood features more than 250 structures in the National Historic Register district, many of them late 1800s mansions of lumber barons and shipping industrialists. You’ll marvel at 150 years of building technology and architecture gracing one of the Great American Main Streets."

Marshall's Territorial Road
Historic Heritage Route

Western End: Marshall west city limit
Eastern End: Marshall east city limit
Length: 2.3 miles
Notes: Designated as a Historic Heritage Route on January 11, 2001.
  From MDOT: "The country’s largest National Historic District in the Small Urban category is the focus of this Heritage Route covering a 14-block area of Marshall. The route features 14 official Michigan historic markers, the most of any Michigan community outside Detroit. The markers recall Marshall’s early importance in Michigan history, especially in areas of government, education, abolition, railroads, unionism and architecture. Marshall’s tradition of historical preservation and restoration began in the 1920s and continues today with one of the Midwest’s finest historic home tours conducted annually since the 1950s."
  The portion of BL I-94/Michigan Ave in Marshall designated as a Heritage Route is the only such route signed in its entirety along an Interstate Business Connection.

Southern End: New! Along US-12 at the Indiana state line south of New Buffalo in Berrien Co
Northern End: New! Ludington
Length: New! ~190 miles
Notes: New! Descriptive text from the "West Michigan Pike" Michigan Historical Marker in New Buffalo:
"At the turn of the twentieth century, deep ruts and sand made West Michigan roads nearly impassable. In 1911, the West Michigan Lakeshore Highway Association was founded to promote the construction of the first improved highway along Lake Michigan in order to bring auto tourists from Chicago to Michigan to support the new resort industry that grew up when logging ended in the region. Completed in 1922, the West Michigan Pike extended from the Indiana state line to Mackinaw City. It was designated one of the first state trunk lines (M-11) in 1917, as part of the Dixie Highway in 1923, and incorporated into the nations first federal highway system as US-31 in 1926. Straightened and realigned over the years, it is also known as the Red Arrow and the Blue Star Memorial Highways. The West Michigan Pike, advertised as 'Lake Shore All the Way Chicago to Mackinaw,' was completed as a paved highway in 1922. Tourists, particularly those from Chicago who sought cooler temperatures by coming to Michigan, gained greater access to communities dotting the Lake Michigan shore between the Indiana state line and the Straits of Mackinac. In 1926 the pike (M-11) was designated US-31. By then, traffic congestion and poor road conditions were again impeding travel. The West Michigan Pike Association, which had started the road, advocated for US-31 to be widened and rerouted in 1929 as a 'superhighway.' A full-blown tourism industry with lodgings, restaurants, and attractions grew up along the West Michigan Pike and flourished into the twenty-first century."
  New! After having been relegated to history for over eight decades, a revival of sorts for the West Michigan Pike becomes reality on July 25, 2016 when the state's newest Pure Michigan Byway (formerly Heritage Route) is unvelied by MDOT, Travel Michigan and local tourism officials in a ceremony at Muskegon's Heritage Landing. Only the portion of the former West Michigan Pike corridor from the Indiana state line northerly through St Joseph, South Haven, Holland, Grand Haven, Musekgon, Whitehall-Montague, and Pentwater to Ludington is designated as part of the new tourist route. Planning for the 21st Century version of the route began in 2006 and was spearheaded by the Michigan Beachtowns association of Lake Michigan shoreline tourist organizations. After studies and historical inventories were compiled over the course of a decade, the West Michigan Pike Historic Byway officially became the second of the tourist routes to be designated under the new banner of "Pure Michigan Byway." (The effort had begun while it was still titled the Michigan Heritage Routes program.)
  New! As with any Pure Michigan Byway route, the West Michigan Pike Historic Byway is designated along state trunkline routes between Indiana and Ludington, even though the historic route of the West Michigan Pike followed a much less direct, often meandering route along the highways that existed in the 1910s and 1920s. The Michigan Beachtowns association, however, is interested in a dual-route approach. According to published statements by the group, "It is the intent of the corridor management entity, the Michigan Beachtown Association, to sign both the byway route and the historic route through each beachtown community, giving potential visitors two opportunities to experience the West Michigan Pike, depending on their time and interests."
