Union County, IL – Drivers traveling through southern Illinois are seeing improved traffic flow today after a major update on Interstate 57.
According to the Illinois Department of Transportation (IDOT), I-57 is now fully open between Interstate 24 and Illinois Route 146, reopening a stretch that has been impacted by long-term construction. The agency confirmed that the concrete overlay portion of the project is complete, allowing traffic to move freely with minimal delays expected.
IDOT said only minor work remains, and any remaining construction activity is expected to cause little to no disruption for travelers. The department added that the entire project is on track to be fully wrapped up by spring 2026.
The reopened segment runs through Union and Johnson counties, a key corridor for commuters, freight traffic, and travelers moving between southern Illinois and the greater Paducah–Cape Girardeau region. Officials say the improvements are designed to extend the lifespan of the roadway while providing a smoother and safer driving surface.
Motorists are still encouraged to remain alert for occasional work crews and to obey posted speed limits when traveling through the area.
IDOT continues to post real-time traffic updates and construction notices on its official social media channels and website.
