It also handles a significant amount of truck traffic, transporting goods to and from Janesville.
#HIGHWAY I39 WISCONSIN DRIVERS#
Steve Theisen, Spokesman for WisDOT, reports that this section of the corridor is a heavily traveled section with many drivers using the interstate as a local commuter route between interchanges. The department decided to leave two of the loop ramps, those with the lowest volume and fewest accidents, which saved the department “significant amounts of money,” Vesperman says.įunding for the project included a $40 million federal grant as part of the Fostering Advancements in Shipping and Transportation for the Long-term Achievement of National Efficiencies (FASTLANE) program in 2016 to support and accelerate construction by two years of a 4-mile segment of Interstate near Janesville between WIS 11/Avalon Road and U.S. “Instead of building the whole interchange for hundreds of millions of dollars, we came up with a solution that costs $100 million and will last for 20 years.” “We identified 16 high-crash safety locations with operational issues,” Vesperman continues. Performance-based practical design is a Federal Highway Administration approach. “One of the coolest things about that interchange is that it’s the greatest example of performance-based practical design,” Vesperman says. 12/18 in June 2020, which will include changing a left exit to a right exit. The department expects to let that last contract for the I-39/90 interchange with U.S. Over $300 million in work is currently under way and $100 million remains to be let. Wisconsin DOT has spent about $800 million so far on the project. Traffic counts are expected to increase to 90,000 vehicles per day by 2040. Trucks make up about 30 percent of volume. It was first built in the 1960s, when far fewer vehicles were traveling the corridor.Ĭurrently about 50,000 vehicles drive on I-39/90 daily, with surges to more than 70,000 vehicles per day in the summer when tourism traffic to the Wisconsin Dells boosts traffic. “There were safety issues, with lots of crashes for many years that had to be mitigated.”Īdditionally, the pavement had started to deteriorate, and the road needed to be brought up to current standards. “There are so many vehicles out there, we had to expand it,” says John Vesperman, I-39/90 Project Chief with the Wisconsin Department of Transportation (WisDOT). Contractors have completed approximately two-thirds of the work on Wisconsin’s $1.2 billion Interstate 39/90 Expansion Project, designed to improve safety, increase capacity and bring the corridor up to today’s interstate standards.
