The McKinley Bridge over the Mississippi River will be closed in both directions Wednesday for repairs, according to the Illinois Department of Transportation.
The closure, which is expected to last from 7:30 a.m. until about 6 p.m., is needed so lighting on the span can be repaired, according to IDOT leaders.

The McKinley Bridge, originally opened in 1910, connects Venice on the Illinois side of the river to St. Louis on the Missouri side. It was closed from October 2001 until November 2007 while major renovations were completed.
