MARION – IDOT says an upcoming road closure is planned for I-57 in Williamson County.

Beginning Sunday, June 11 at 7 p.m., both directions of I-57 will be closed to all traffic between exits 45 and 54 so new structural steel can be erected on the bridge carrying Westminster Drive over I-57 south of Marion. All lanes will be re-opened Monday, June 12 at 7 a.m.

A marked detour will be in place to direct northbound and southbound traffic around the work zone between exits 45 and 54. The detour will utilize Illinois 13 and Illinois 148 for both directions of travel. The northbound on-ramps at Old Illinois 13 and Illinois 13 will remain open.

Flaggers, message boards and traffic control devices will be used to inform and direct motorists.
