More Interstate Shields and Signs

This set is from Ohio and Michigan.
 

This is an Ohio I75 shield, taken at the US6 exit north of Lima.

This is the end of Business Loop 75 in Sault Saint Marie, by the place where the Ferry to Sugar Island stops.

 Exit 215's Business Loop Sign, on its exit off I75 North.

From the Upper Peninsula, off Michigan 28, headed Eastbound, West of Seney.
Do Not Pass When Opposing Traffic Present. This could be on a Seinfeld.
