ST. LOUIS – Work to close the eastbound I-255 bridge across the Mississippi River (Jefferson Barracks) Bridge and shift two lanes of traffic to the westbound bridge has been delayed due to weather.
The Missouri Department of Transportation is now planning to close the eastbound I-255 bridge across the Mississippi River (the Jefferson Barracks) bridge and shifting traffic onto the westbound bridge, starting at 8 p.m. Tuesday, April 19, weather permitting. One lane in each direction will close, and the remaining two lanes in each direction will be narrowed and shifted on the westbound bridge by 5 a.m. Wednesday, April 20. Trucks are encouraged to stay in the left lanes of both eastbound and westbound I-255 as they cross the bridge.
Since the project also includes work at the eastbound I-255 bridge over Koch Road, the ramp from Koch Road to eastbound I-255 will also be closed at that time through December. Drivers on Koch Road who want to travel east can use Telegraph Road to get onto eastbound I-255.
While the eastbound bridge is closed, drivers can expect that congestion levels will be high during the morning and evening rush periods, and should consider either adjusting their routes or times, or allowing extra time to cross through the work zone.
The eastbound bridge will remain closed through December so crews can complete needed preventative maintenance identified during recent bridge inspections. This work will help keep the bridge safe and operational for the foreseeable future.
