For 76 years, from 1926-2002, US-27 was a primary highway in the state of Michigan. During the Postwar highway expansion era on the even of the Interstate Highway system, US-27 was extended to St. Ignace, Michigan, across the Mackinac Bridge. However, as I-75 was completed in sections north of Tri-Cities area, US-27 was eventually truncated to just north of Higgins Lake in 1961.
As Interstate 69 was completed in the 1970s around the Charlotte area, US-27 was moved onto the new Interstate freeway. In 1991, MDOT petitioned AASHTO, to have US-27 removed from the state of Michigan’s highway network. This request was denied because MDOT made no mention of their plans for US-27 north of Lansing. However, eight years later on in 1999, they submitted another application, and AAHSTO approved the request to truncate US-27 from south of Grayling to Fort Wayne, Indiana. The end finally came in 2002, when all of the old US-27 marker signs were removed.
When I think of US-27 and the many other U.S. Highways in Michigan, this two-lane photo from the Michigan State Highway Dept. comes to mind. This image was shot in Clare County, near the community of Harrison during Labor Day in 1955. I can just image driving along this hilly and winding highway at 105 km/h (65 mph), and having a deer run standing in the roadway as I crested the hill.
