Governor Evers announces construction date for WIS 15 expansion in Outagamie County

​Construction will begin September 2021

Release Date: June 20, 2019

(Hortonville, Wis.) Governor Tony Evers today announced construction will begin in September of 2021 on the WIS 15 expansion and bypass project in Outagamie County. The project will expand 11 miles of WIS 15 to a four-lane divided highway from Lily of the Valley Drive in the town of Greenville to US 45 in the city of New London with a bypass around the village of Hortonville. Governor Evers made the announcement at a press conference at the Hortonville Municipal Center.

“The growing volume of traffic along this highway corridor, the number of traffic crashes, injuries and fatalities demand our collective action,” said Governor Evers. “Today, we are finally announcing a commitment to move this important expansion project forward.”

The Transportation Projects Commission enumerated WIS 15 expansion in 2011, with construction originally scheduled to start in 2017. Prioritization of other major highway project needs, combined with past funding availability, contributed to the change in schedule for WIS 15.

Governor Evers was joined at the announcement by Wisconsin Department of Transportation (WisDOT) Secretary-designee Craig Thompson, state officials and local leaders who recognized the need to get this long-planned project underway as soon as possible. Governor Evers noted collaboration was key to get the project started – again.

“Despite the many years that have passed, the same concerns identified a decade ago remain along this 11-mile corridor, with the primary concern being public safety,” said Governor Evers. “It’s my hope that the bi-partisan cooperation behind this project will carry over to the larger discussion we’re having now about Wisconsin’s transportation future.”

Secretary-designee Thompson noted traffic forecasts along the corridor exceed the threshold for a 4-lane facility, and without expansion, WIS 15 has a failing level of service by 2040.  In addition, heavy regional traffic currently conflicts with local traffic through Hortonville.  Studies show 75% of eastbound traffic and 52% of westbound traffic have destinations beyond the village. Crash rates along WIS 15 east and west of the village are higher than the statewide average, and three fatalities have occurred in the past nine months.

“The bottom line: the growing amount of traffic is simply too high to have a major highway dissecting Hortonville,” said Secretary-designee Thompson. “Expansion is the best way to provide additional roadway capacity and improve operational efficiency and traffic safety.”

The $138.7 million project will also construct roundabouts on either side of the village where the bypass meets existing WIS 15. Construction is expected to finish in 2024.
