The Wisconsin Department of Transportation (WisDOT) has begun a $1.7 billion expansion of Interstate 94 in Milwaukee to improve safety, traffic flow, and regional connectivity. The eight-year project will widen a 3.5-mile section between 16th and 70th streets from six to eight lanes.
Work on the “West Leg,” extending from 70th Street to Zablocki Drive, began November 3 and is scheduled for completion in 2028. The “East Leg,” from 35th to 17th Street, will follow through 2030, with full corridor completion expected by 2033.
The project is funded through the Federal Highway Administration, which will cover 80 percent of costs, with 20 percent provided by state highway funds.
Major interchange work includes converting the Stadium Interchange into a diverging diamond, reconstructing the Hawley Road Interchange as a half-interchange, and upgrading the 68th and 70th Street ramps.
Construction will involve long-term lane and ramp closures. WisDOT said the project will replace aging infrastructure, enhance safety, and reduce congestion along one of Wisconsin’s busiest corridors, which carries up to 178,000 vehicles daily.
