Major 4-Year Construction Project Begins On I-75 In SE Michigan
Michigan has committed $160 million to a four-year construction project on I-75 for resurfacing and repairs. According to the Michigan Department of Transportation, the construction project in Oakland County will involve milling and resurfacing approximately 15 miles of I-75 in both directions. The project spans from Ortonville Road (M15) to the Oakland/Genesee County line which is three lanes of the highway.
When does the project start?
The project began at 7 am on Monday, May 22. As part of the bridge repairs, workers closed Belford Road, Davisburg Road, and Holcomb Road, all of which pass over I-75. These closures are anticipated to continue until late July, while I-75 will remain open below the bridges.
Starting Monday evening, the left two lanes of the highway, spanning from Dixie Highway to Davisburg Road east of Holly, will be closed until June 12. The construction work in that section is scheduled to take place overnight, specifically between 8 p.m. and 5 a.m.
How long will it last?
From late May through the fall, lane closures may be necessary along the 15-mile stretch of I-75 due to pavement repairs. Additionally, temporary crossovers will be constructed to facilitate the bridge work. However, as of Friday, May 19, the complete construction schedule had not been announced.
In 2024, the construction plan involves milling and resurfacing the northbound lanes of I-75, from M-15 to the county line. During this phase, two lanes of traffic will share the existing southbound roadway in both the northbound and southbound directions.
Moving on to 2025, the focus will shift to milling and resurfacing the southbound lanes of I-75, covering the section from the county line to M-15. Traffic will be redirected to the existing northbound roadway to accommodate this work.
Finally, in 2026, the remaining activities will occur, including removing the temporary crossovers and addressing any miscellaneous tasks related to the project.
Michigan: Our 1 Mile Freeway + More Fun Facts About Our Roads
Michigan's shortest freeway is 1.1 miles long.
Currently, Michigan has one of the nation’s shortest signed interstates. The shortest freeway in Michigan is only 1.1 miles long. Though not signed, New York has a 0.70 miles freeway, which is even smaller than Michigan’s smallest.
Michigan has the longest remaining camelback bridge.
The three-span US-12 camelback bridge in Mottville is Michigan’s longest remaining bridge of this type. Constructed in 1922, these bridges are found primarily in Michigan and Ontario, Canada.
Michigan has a bridge with towers almost as tall as the Washington Monument.
The towers on the Mackinac Bridge or “Mighty Mac” (552 feet high) are almost as tall as the Washington Monument (555 feet high). The Mackinac Bridge is currently the fifth longest suspension bridge in the world.
Michigan's first road map only had 3 roads on it.
The first Michigan road map, with only three roads on it, was published by the United States Congress in 1826. As a matter of fact, the first surveyed road in Michigan was Pontiac Road (now called M-1 or Woodward Avenue) connecting Detroit and Pontiac in 1819.
Michigan has the only state highway in the nation where motor vehicles are banned.
M-185 on Mackinac Island is the only state highway in the nation where motor vehicles are banned. Motorized vehicles have been prohibited on Mackinac Island since 1896 because the horses were disturbed by the noisy engines of some of the island’s first cars. Furthermore, carriage drivers formed an association, convincing islanders to ban automobiles.
The longest highway in Michigan passes through six different states.
The longest highway in Michigan is I-75, which runs 395 miles from the Ohio border to the International Bridge in Sault Ste. Marie. I-75 also passes through six different states. At its north end, it starts on the Canada/U.S. border at the top of Michigan at Sault Ste. Marie. Then it heads south to Naples in Florida, where it bends east and runs across to Miami.
Michigan has a total of 120,256 miles of paved roadway.
MDOT says that there is enough pavement on Michigan roadways to build a one-lane road from the Earth to the moon. Michigan has a total of 120,256 miles of paved roadway. This includes 9,669 route miles of state trunkline, 89,444 route miles of county roads, and 21,198 route miles of city and village streets. However, according to NASA, the Moon us an average of 238,855 miles away from Earth.
Several Michigan highways began as Native American trails.
Eight Michigan highways began as Native American trails, US-2 (from Sault Ste. Marie to Green Bay); I-75 (from Detroit to Saginaw), I-94 (from Detroit to St. Joseph; I-96 (from Detroit to Grand Rapids), I-94 (from Detroit to Port Huron), US-41 (from L’Anse to Marquette), and US-12 (from Ypsilanti to Chicago). Michigan’s three largest tribes are the Ojibwe (also called Chippewa), the Odawa (also called Ottowa) and the Potawatomi (also called the Bode’wadmi). Michigan also federally recognizes these tribes and others in the state.
