Wisconsin Highway 311

State Trunk Highway 311 (STH-311, WIS 311) is a state trunk highway which runs for 2.0 mi in the village of Mount Pleasant, Racine County, Wisconsin. The highway acts as a frontage road to Interstate 41/Interstate 94 (I-41/I-94), providing access to the Wisconn Valley Science and Technology Park developed by Foxconn.

Route description
WIS 311 meanders along a four-lane divided roadway in its entirety, which is sandwiched in between I-41/I-94 to the west and a Foxconn plant to the east. There are only three intersections, all signalized, throughout the route. The roadway starts at County Trunk Highway KR (CTH-KR) at the Somers–Mount Pleasant line, then curves slightly to the west and east before intersecting with Braun Road. The road then curves slightly to the west and then takes on a northeastern direction before ending at WIS 11.

History
Construction on Wisconn Valley Way was slated to begin in April 2019 and finish by the end of the year. The project was part of infrastructure improvements to support the Foxconn plant in Mount Pleasant. The Wisconsin Department of Transportation (WisDOT) awarded a contract for $16.9 million (equivalent to $ in ) for the work. The roadway was named by former Governor Scott Walker and former Foxconn CEO Terry Gou. The roadway opened on January 17, 2020.

Officials at WisDOT sent a letter to residents in Racine County on May 12, 2022, stating that Wisconn Valley Way would receive a state highway designation under the WIS 311 name. Initial reports stated that the Wisconn Valley Way name would be replaced, but this was clarified to state that the designation would not supplant the local road name.
