The Illinois Department of Transportation (IDOT) announced that a full closure on eastbound Interstate 55/70 from the Interstate 55/70/64 interchange in East St. Louis to Interstate 255 near Collinsville is scheduled to begin on Friday, August 18, weather permitting.  Starting at 9 p.m. Friday, eastbound Interstate 55/70 will be closed from the Interstate 55/70/64 interchange to Interstate 255.  A posted detour will direct traffic to take eastbound Interstate 64 to northbound Interstate 255 to access eastbound Interstate 55/70.  Eastbound Interstate 55/70 traffic will not be able to travel east of the Interstate 55/70/64 interchange.  The closure is necessary to make bridge repairs on a bridge west of Illinois 203, to perform pavement repairs on Interstate 55/70 west of Interstate 255, and to paint two bridges west of Interstate 255. In addition to the above closure, the right lane of eastbound Interstate 55/70 will be restricted from Black Lane to Interstate 255 near Collinsville from 9 p.m. Thursday night and continuing through Friday.  This lane restriction is necessary to prepare for the above closure. The interstate is expected to reopen by 5 a.m. Monday, August 21. Motorists are advised to seek alternate routes and anticipate some longer travel times. By utilizing a full expressway closure and keeping construction restricted to the weekend when traffic volumes are down, IDOT aims to reduce the length of time the work zone is needed during heavier traveled weekday periods.
