QuoteThe cracking on the westbound Jefferson Barracks Bridge span, which carries I-255 from Monroe County to south St. Louis County, was discovered Sunday afternoon during a routine MoDOT inspection.
Tom Blair, the agency's St. Louis area district engineer, said the main concern is a 6-foot-long crack in the weld connecting the bridge's arch to a steel beam below the driving surface.
"That juncture is very critical from a structural stability point of view," Blair said. He also said it is very unusual for the type of bridge involved.
He said that after the discovery, MoDOT called in a dozen or so specialized inspectors to scrutinize the entire westbound span to see whether there were any additional cracks.

Not good news for the Westbound bridge...The tests are awaiting full results, but apparently MoDOT is already considering ultimately routing WB traffic on the EB bridge

Short version: 2 Westbound lanes will be open on the WB bridge during weekday morning rush hours (5 am-10 am), and 1 Westbound lane other times. Oversize and Overweight loads will be prohibited, until repairs can be completed
