ST. LOUIS COUNTY, Mo. — Inspection and construction crews are making progress on the westbound lanes of the Jefferson Barracks Bridge carrying I-255 over the Mississippi River, but there is still no time set for when the bridge will reopen.

In a press release, the Missouri Department of Transportation said inspection crews are expected to finish their in-depth evaluation Thursday afternoon. Inspectors are waiting for lab results of the section of the bridge where cracks were found.

Once the lab reports are in, MoDOT will be able to decide if the bridge is safe or if they will have to consider constructing a cross-over lane to use eastbound lanes for westbound traffic.

Meanwhile, MoDOT and IDOT have awarded emergency contracts to get additional resources and start work on needed repairs. Two private companies — as well as crews from MoDOT and IDOT — are working on the bridge.

The westbound lanes of the bridge were closed Sunday evening after cracks were discovered during a routine check of the bridge.

MoDOT said crashes in the area contributed to commute times Wednesday morning. They are asking drivers to plan extra time into their commutes and drive safe.
