The Missouri Department of Transportation said that work to close the eastbound span of the Jefferson Barracks Bridge on I-255 and shift two lanes of traffic to the westbound bridge has been delayed multiple times due to weather.

At this time, crews are now planning to close the eastbound bridge and shift traffic onto the westbound bridge starting at 5 p.m. Saturday, April 23, weather permitting.

One lane in each direction will be closed, and the remaining two lanes in each direction will be narrowed and shifted on the westbound bridge by 8 a.m. Sunday, April 24. The ramp at Koch Road to eastbound I-255 will also close at that time.

Trucks are encouraged to stay in the left lanes of both eastbound and westbound I-255 as they cross the bridge.

The eastbound bridge closure was initially expected to take place April 15, but heavy rainfall last week and more rainfall this week dampened those plans.

While the eastbound bridge is closed, drivers can expect congestion levels to be high during the morning and evening rush periods, MoDOT warned, and should consider either adjusting 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 preventative maintenance identified during recent bridge inspections. This work will help keep the bridge safe and operational for the foreseeable future, MoDOT said.

Next spring, the westbound bridge will be closed and traffic shifted to the eastbound bridge for similar repairs.
