In particular, MDOT restored the old truss bridge over the Au Sable River in Iosco County, and then built a new parallel and upgraded bridge next to it. The latter straightened and leveled the roadway, so that it no longer dips deep into the river valley. This change improved the safety of the highway in the area. The new bridge was opened to traffic on October 13, 2004, and the original bridge was left in place for recreational uses. The original structure is a Parker truss bridge with two spans that was built in 1930. Its total length of makes it one of the longest of its type in Michigan.
