The City of Marquette, Michigan, has gravel streets in some neighborhoods not far from the campus of Northern Michigan University. They will be paved in the near future now that the city has agreed to assume the cost of improvement instead of special direct property tax assessments against the adjacent property owners.
Traverse City, Michigan, has several brick streets including blocks of Sixth, Seventh and Eighth streets south of downtown. As a kid, Cheboygan, Michigan, would have to lift the bricks used to pave the northernmost block of Main Street each winter. They'd reset them in the spring after the frost left the ground. I do believe that they finally paved the street in asphalt though.
