The southbound lanes of Interstate 55 between Hamel and Edwardsville will be restricted to one lane during nighttime hours, according to the Illinois Department of Transportation.

Between Exits 30 and 23, the lanes will be restricted between the hours of 7 p.m. and 6 a.m. IDOT says work is expected to be completed by Tuesday, Aug. 20 and is necessary to repair the pavement marking.

Drivers should expect delays and are asked to use alternate routes during this time. Drivers are also urged to reduce speed, be alert for changing conditions, obey all construction signage and refrain from using mobile devices while approaching and traveling through the work zone.
