State Trunk Highway 157 (often called Highway 157, STH 157 or WIS 157) is a short state highway in the U.S. state of Wisconsin. It runs east on Main Street from Highway 35 (Second Avenue) in downtown Onalaska to the U.S. Highway 53 freeway. There it turns south, running concurrent with US 53 to the Interstate 90 interchange. US 53 leaves Highway 157 to head west on I-90, but Highway 157 continues southeast to Highway 16 at the Valley View Mall.

According to the La Crosse Area Planning Committee's 2030 Metropolitan Area Transit Plan, the route may not remain Highway 157 forever. The plan suggests that following the completion of an extension project on U.S. Highway 53 (planned for 2012-2015), the Main Street portion will become a local street, with the rest becoming part of Highway 53.[1]
