IL – Commuters traveling through the interchange of I 55 and I 80 should prepare for overnight traffic disruptions as the Illinois Department of Transportation initiates a series of scheduled road closures. The work is slated to take place beginning September 9, 2026, and concluding on September 10, 2026, to accommodate necessary bridge construction at the heavily traveled junction.
According to the Illinois Department of Transportation, the project will require specific overnight shutdowns of the main thoroughfare. Northbound I 55 is scheduled to be closed to traffic on September 9, 2026, starting at midnight and reopening at 5 a.m. Following this, the Southbound lanes of I 55 will undergo a full closure on September 10, 2026, also running from midnight to 5 a.m.
The construction effort will impact more than just the immediate interchange. Officials noted that lane reductions are necessary to prepare the roadway for the full closures. These reductions are scheduled to begin at 8 p.m. on westbound I 80 and at 9 p.m. on I 55 prior to each full closure event. Motorists are encouraged to plan their routes accordingly to avoid potential delays during these designated timeframes.
Those seeking further information or updates regarding the project status are encouraged to visit the official project information page at https://www.facebook.com or contact I 80 Will for additional details as the work progresses. Travelers are advised to exercise caution and remain alert for changing traffic patterns near the I 80 and I 55 interchange while construction crews are on site.
