Rockford, IL – The Illinois Department of Transportation has officially opened the new diverging diamond interchange at Interstate 39 and U.S. 20/Harrison Avenue, marking a major milestone for Rockford-area commuters.
According to IDOT, the project reconstructed U.S. 20/Harrison Avenue, added a dedicated bike and pedestrian path, upgraded lighting, and redesigned traffic patterns to handle more than 50,000 vehicles per day. The improvements aim to enhance safety and reduce congestion during peak travel times.
The diverging diamond interchange (DDI) is Illinois’ eighth and the first of its kind in the Rockford region. The DDI design allows vehicles to briefly shift sides while crossing the bridge, eliminating left-turn conflicts and improving overall traffic flow.
Officials say the interchange will provide smoother and safer travel for drivers entering and exiting I-39 and U.S. 20, while offering better pedestrian access across the busy corridor.
Commuters are encouraged to stay alert while adjusting to the new traffic pattern and follow posted signs for lane guidance.
