Comprehensive improvements will address aging infrastructure and future transportation needs

Jacobs (NYSE:J) has been awarded roles on multiple design contracts by the Wisconsin Department of Transportation (WisDOT) to advance modernization and expansion of the I-39/90/94 corridor, one of the state's most critical and heavily traveled transportation routes. The program will reconstruct and widen key segments to improve safety, ease congestion and support long-term economic growth.

Built in the 1960s, the corridor serves as a vital connector for commuters, freight and tourism, carrying up to 109,000 vehicles per day and more than $100 billion in freight annually.

Under the new contracts, Jacobs will deliver design services across several modernization segments spanning 67 miles from Madison to Wisconsin Dells, including serving as lead designer for Segment 3, which features the I-39 I-90/94 system interchange.

Jacobs Executive Vice President Tom Meinhart said: "Jacobs has been part of Wisconsin's growth story for decades, delivering transformative water and transportation solutions and working with communities across the state. That history reflects a commitment to innovation and resilience, and the I-39/90/94 modernization builds on that legacy. By leveraging our deep experience and local relationships, we're creating safer, more efficient connections that strengthen commerce, improve mobility and enhance quality of life for generations to come."

Design for the corridor will begin in 2026, with phased construction to follow. Planned upgrades include interstate widening, interchange and bridge reconstruction, three new interchanges and raising roadway elevation to reduce impacts from flooding.
