Known as one of the most well-traveled passages in the state of Wisconsin and the greater Midwest region, I-39/90 has been suitably nicknamed, “The Gateway to Wisconsin”. This vital corridor connects many of the region’s urban areas from Chicago to Minneapolis through an established system of interstates and highways. In 2019, a 45-mile stretch of roadway, spanning from Wisconsin’s southern border to Madison, underwent construction to improve safety and address increasing traffic demands.
The project outlined the expansion of the four-lane interstate to accommodate up to six and eight lanes of traffic in highly congested areas. These upgrades warranted the reconfiguration of 11 interchanges and the addition of over 10 miles of stormwater infrastructure. Due to the project’s substantial size, Hoffman Construction of Black River Falls, WI and Rock Road Companies of Janesville, WI were brought on-site to work on separate sections of the road simultaneously.
