^A westbound guide marker for M-45 at the east end of the route, which occurs at I-196 in the Grand Rapids metropolitan area, March 2019.
Michigan Highway 45 is a short east-west highway from Grand Rapids west toward Lake Michigan. The eastern end is at Interstate 196 and Lake Michigan Drive. Lake Michigan Drive becomes occupied by Michigan Highway 45 west of here. Michigan Highway 45 continues west to US Route 31, only a few miles from Lake Michigan's shoreline. This western endpoint is south of Grand Haven but north of Holland.
My photo of Michigan Highway 45 comes from its junction with Michigan Highway 231, southeast of Grand Haven. The guide assembly faces west for eastbound traffic on Michigan Highway 45. This photo was taken on the way to Traverse City in early March, 2018.
