MARION (WQRL/WISH/WMCL) – IDOT says both directions of I-57 from mileposts 45 to 54 in Williamson County will be closed starting at 7 p.m. on Sunday, Jan. 15 so the bridge carrying Westminster Drive over the interstate south of Marion can be demolished. All lanes will be reopened on Monday, Jan. 16 at 7 a.m.

A marked detour will be in place to direct northbound and southbound traffic around the work zone between mileposts 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.
