Interstate 75 is one of Michigan's longest numbered highways within the state. It begins at the state line just north of Toledo and runs to Detroit then heads towards Pontiac and then north to Bay City. It then heads towards the middle of the state going northwest then up to the Mackinac Bridge and finally to the Canadian border at Sault Ste. Marie. The total length in the state is 395 miles (636 km).

[edit] Mileage signing

Even though Saginaw is the control city for southbound Interstate 75 from Mackinaw City to just north of Interstate 675, Detroit and Flint are often shown as cities for long distance on the mileage signs as far north as the Mackinac Bridge. Just south of the Bridge, Detroit is listed as 288 miles (463 km) away, making it the largest distance for any city listed on the Interstate 75 corridor. Even though Interstate 75 does not go near Lansing at all, the Michigan state capital is still listed as 224 miles (360 km) just south of the Mackinac Bridge, on the same mileage sign. Flint is listed on another mileage sign, as 214 miles (344 km) away, further down Interstate 75.

This helps motorists who have to travel far to reach their destinations. It also makes sense for Detroit to be mentioned, since it is the largest city in the state.

[edit] Spur Routes

I-275 - Begins as a loop from Northern Monroe County and continues to connect up with Interestate 696. Was going to connect back up with I-75 north of Pontiac. Serves the Western population centers of Wayne County and the Metro Airport.

I-375 - Is the shortest signed Interstate in the nation. It serves the immediate downtown Detroit area.

I-475 - Known as the U.A.W. Freeway. Serves Flint's downtown areas as I-75 goes to the west side of the city.

I-675 - A loop into the city of Saginaw and back out north of the city. Served as an alternate to I-75 when the drawbridge over the Saginaw River was still operating.

[edit] History

Before any segment of freeway in Michigan received a designation of Interstate 75, there were already segments of freeway built which are now part of I-75. These freeway segments were built from the mid to late 1950s; they include:

  • US 2 between what is now known as BL I-75 in St. Ignace and M-123. The Upper Peninsula's first segment of freeway.
  • Alt US 24 between Ohio border and US 25 (now M-125) - Michigan's first segment of freeway to connect the state border; and the only freeway to cross the border until the late 1960s.
  • Mackinac Bridge (then US 27)
  • M-20 (now part of US 10) - when this segment of freeway became US 10; it carried the temporary Interstate 75 designation.

The most congested portion of Interstate 75 within Michigan is the stretch between Flint and Saginaw. This stretch has had constant additions of lanes due to the urban sprawl that has occurred between the 2 towns.

This list is incomplete; you can help by expanding it.

In Detroit, the spur route I-375 is the shortest signed spur of I-75 at 1.06 miles (1.71 km). Interstate 375 is the shortest signed interstate highway. In addition, at that same junction, the I-75 curve where it shifts from the Fisher Freeway to the Chrysler Freeway is one of the sharpest on a mainline route in the entire Interstate system, with a 25 mph (40 km/h) advisory speed.

I-75 connects Michigan's Upper and Lower Peninsulas via the 5-mile (8.0 km) long suspension Mackinac Bridge.

At the northern end of I-75, at Sault Ste. Marie, Michigan, the Sault Ste. Marie International Bridge leads into Canada, into Sault Ste. Marie, Ontario. This is the closest connection of any Interstate to the Trans-Canada Highway. However, there is no direct freeway connection; bridge traffic funnels onto city streets.

The section between Grayling, Michigan and M-32 (Michigan highway) was built in 1961. This section was built by converting the northbound lanes of U.S. Route 27 to southbound lanes and building a new set of northbound lanes leaving the former southbound lanes as a strip of grass, most likely because of plans to upgrade that stretch to Interstate Highway standards. The terminus of the freeway near downtown Grayling was converted to a partial interchange for what would become BL I-75 between that and M-93/Hartwick Pines Road.

Alongside that, the former segment of US 27 between Grayling and Gaylord, Michigan was turned back to local control. After this individual segment of freeway was completed, it left a gap between Gaylord and Indian River which was filled in a year later. While the gap was being filled in, a special "TO I-75" designation was applied to the former segment of US 27. Around that time, US 27's northern terminus was scaled back to 5 miles (8.0 km) south of Grayling until it was redesignated as an extension of US 127 in 2001.

Until the early 1970s, I-75 between Bay City and Grayling was routed west to Clare (along US-10 then north along then-US-27, and was signed as "TEMP I-75". This freeway segment had some at-grade intersections at the time. In 2002 the portion between Clare and Grayling was redesignated as an extension of US 127, although it was posted as US 127 on a National Geographic road atlas in the year 2000.

In the 1960s, I-75 had several discontiguous segments connected with roads with "TO I-75" signs in addition to US 10 doubling as "TEMP I-75".

The routing between Alger and Roscommon was completed in 1973, and the temporary section reverted to U.S. routes, although of freeway quality.

Until the completion of I-75 in 1973, the stretch of expressway between Standish and West Branch had the designation of M-76. When the I-75 signs were erected along the expressway, M-76 vanished from the state road map after 53 years of existence.

Until 1987, US 10 and I-75 were the same road between Bay City and Clarkston. Both also overlapped US 23 between Bay City and Flint. Now, Bay City serves as the eastern terminus of US 10.

As late as 1990, US 31 and US 23 both had their northern termini on I-75's southern approach to the Mackinac Bridge. Even though US 27 was scaled back 94 miles (from Mackinaw City to south of Grayling) in 1961, a lone sign assembly showed all three US highways ending at the same place as late as 1971.

As recently as 2007, many revisions have been done to I-75 in much of Michigan. Many of the solid white and yellow lines indicating non-travel lanes (shoulders) have been marked with a double line for extra indication to make the rumble strips more visible. Also, the overpass signs for Cheboygan-Levering Road and Miami Beach Road have been renamed to Levering Road and Mullet-Burt road respectively. Also, the stretch of I-75 between Flint and Saginaw has been upgraded from 3 lanes on each side to 4 lanes on each side; the Bay county stretch between I-675 and CONN M-13 is scheduled to be upgraded from 3 lanes to 4 lanes on each side in the near future. Other revisions include replacing mile markers with big vertical digits to ones with smaller horizontal digits along with the route number and direction, and upgrading freeway signs with the Clearview font.

The G. Mennen Williams Freeway is the name given to the portion of I-75 in Cheboygan County, Michigan beginning at the southern end of the Mackinac Bridge and proceeding southerly. The Prentiss M. Brown Freeway is the name given to the portion of I-75 in Mackinac County, Michigan beginning at the northern end of the Mackinac Bridge and proceeding northerly. The (Walter P.) Chrysler Freeway is a section of I-75 between downtown Detroit and Pontiac, and is one of busiest segments of I-75 and hosts one of the perennially busiest segments of freeways in Michigan. The Chrysler continues south as I-375.
