MDOT's Highways and Local Names

A Web link designed to help motorists locate the local names of state trunkline roads and highways (M, I and US roads).  The link provides users with a database of more than 3,000 records, listed in numerical order by MDOT region.  Each entry is then displayed by highway number, local name and county. A color-coded map makes it easy to locate regions. The database also can be sorted by county.
