State Trunk Highway 15

Home » Guides » Wisconsin » State Trunk Highway 15

Wis 15 is a major commuter route between New London and Appleton. It was constructed as an expressway to bypass the Fox River Mall area and was completed in 1998. The route was cosigned with U.S. 45 between Greenville and New London in preparation for the route to be signed solely as Wis 15 after construction projects were completed on the relocated route of U.S. 45.

Wis 15 was formerly used along the entire length of the Rock Freeway between Beloit and Milwaukee, but was replaced with an extension of Interstate 43 in 1987.

Future plans will upgrade Wis 15 between New London and Greenville to four lanes with a freeway bypass of Hortonville. Construction is set to begin in 2018.
