MoDOT has closed the westbound lanes of the Jefferson Barracks Bridge, the southernmost span linking Illinois to Missouri in the St. Louis region. It was closed Sunday as MoDOT Joe Molinaro, Bridge Engineer for the St. Louis Region says crews inspecting the bridge on I-255 found a crack on a steel beam the underside of the bridge's westbound span. 

He says as of now, there is no good estimate on identifying a fix and making repairs, but MoDOT now anticipates it will take at least until the end of the week. Molinaro notes the eastbound lanes were also inspected on Sunday, and has been deemed safe. The closure produces even more bottlenecks, as the MLK Bridge leading into St. Louis is closed for repairs, and the lower lanes of US 67 just south of Alton remain closed due to flooding.
