US Route 223 is a short highway in the southeast corner of Michigan, running west-northwest from the Ohio border near Toledo. The northwestern end of US Route 223 is at US Route 127, just south of US Route 12 and Cement City. This northwestern terminus is about 15 miles south of Jackson, Michigan. US Route 223 serves Adrian and Blissfield before reaching US Route 23 just a few miles north of the Ohio border. For some reason, US Route 223 joins US Route 23 south to the first exit beyond the Ohio state line, instead of ending at the interchange where it meets US Route 23. That exit, at Sylvania, Ohio, is only at a mere state route, Ohio Route 184.
My photo of US Route 223 in Michigan comes from the side of Michigan Highway 34 in Adrian. Michigan Highway 34 passes under US Route 223, but a state-sanctioned connector route joins the two routes, serving those looking to reach one route from the other. The signage depicted helps westbound travelers on Michigan Highway 34, pointing out where to turn in order to reach US Route 223. This sign photo was taken in March 2019, as I was driving around central and south-central Michigan.
