All eastbound lanes will be closed for I-55/70 work in Madison County

The Illinois Department of Transportation announced that a full closure on eastbound Interstate 55/70 from Illinois Route 111 near Fairmont City to U.S. 40 near Troy is scheduled to begin on Friday, Sept. 13, weather permitting, and last throughout the weekend.  The closure is necessary for placing a new bituminous surface treatment on the roadway.

Starting at 7 p.m. Friday, all lanes of eastbound I-55/70 will be closed from 111 to U.S. 40.  A posted detour will direct through-traffic to take eastbound I-64 to northbound I-255 to eastbound I-270 to access eastbound I-70 and northbound I-55.

The closure is expected to reopen by 7 a.m. Monday, Sept. 16.

 Drivers are encouraged to use the posted detour throughout the weekend closure.  The closure will increase traffic on the detour route and other alternate routes in the area, therefore, allow extra time for all trips in and throughout the surrounding area.  Drivers should be patient, reduce speed, be alert for changing conditions, obey all construction signage, and refrain from using mobile devices while approaching and traveling through the detour area.

The contractor on the project is Micro-Surfacing Contractors, Inc. of St. Louis, Missouri.
