State Trunk Highway 31 (often called Highway 31, STH 31 or WIS 31) is a state highway in the U.S. state of Wisconsin. It runs north–south as a suburban route passing Racine and Kenosha. With the exception of a two-mile (3 km) stretch between Four Mile Road and Wisconsin Highway 32 at the north end, WIS 31 is a multi-lane urban highway. An expansion of the remaining two miles was proposed by the Wisconsin Department of Transportation.
Route description
