^Looking east from the intersection Michigan 211 in Onaway, August 2022.
Michigan Highway 68 is the northernmost east-west state highway stretching all the way across the Lower Peninsula. It doesn't hug the northern shore of the Peninsula by any means, but it's the first highway you'll encounter if you head south of that northern shore. The western end is in Alanson at US Route 31. Farther east, Michigan Highway 68 meets Interstate 75 at Indian River, and it meets Michigan Route 33 at Onaway. Onaway is the last intermediate town that Michigan Highway 68 passes through; the eastern end is at the final town served by the state highway: Rogers City. Rogers City, on the shore of Lake Huron, is where Michigan Highway 68 ends at US Route 23's business alignment.
My photo of Michigan Highway 68 shows the first eastbound reassurance marker, telling travelers where they are as they turn off of US Route 31 in Alanson. The sign faces west at cars leaving the intersection. This photo was taken in August 2020, along a drive from Mackinaw City to Traverse City. (That trip involved several other Michigan destinations before that, too.)
Here are some more photos taken along Michigan 68:
