Full closure of Illinois 157 and Illinois 162 intersection begins Feb. 26

GLEN CARBON – The Illinois Department of Transportation today announced a full closure of the intersection of Illinois 157 and Illinois 162 in Madison County starting, weather permitting, at 7 a.m. Thursday, Feb. 26.

During the closure, traffic will not be permitted on Illinois 157 and Illinois 162 at the intersection. Both eastbound and westbound Illinois 162 will be closed, and neither will have access to Illinois 157.

A signed detour will be in place as follows:

The closure is necessary to construct two new bridges, a new signalized four-way intersection, and bike and pedestrian accommodations. Illinois 157 and the eastern leg of Illinois 162 are expected to be completed by Oct. 31. Completion of the overall $17.6 million project, including the western leg of Illinois 162, is expected by July 31, 2027.

Motorists should expect delays and are encouraged to use alternate routes during this closure. Drivers are 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.

Over the next six years, IDOT is planning to improve 7,107 lane miles of highway and 8.4 million square feet of bridge deck as part of Rebuild Illinois, which is investing $33.2 billion into all modes of transportation. Accomplishments through Year Six of Rebuild Illinois include almost $20.8 billion of improvements statewide to 21,309 lane miles of highway, 815 bridges and 1,181 additional safety improvements.
