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.

An estimated $134.7 million project upgrades Wis 15 between New London and Greenville to four lanes with an expressway bypass of Hortonville. The preferred corridor for the realignment and expansion of Wis 15 was selected in June 2007. Work on the Hortonsville Bypass got underway in June 2021 and was finished in November 2023. Widening of Wis 15 between CTH-JJ and Lily of the Valley Drive was underway between April 2022 and November 2023.¹

Construction for the West Segment of the Wis 15 Highway Expansion project upgrades the two lane route into a four lane expressway between U.S. 45 and CTH-T (Givens Road). Work commenced in April 2024 and extends to late 2024.¹
