Welcome

Construction work on the Mississippi River Bridge project has begun.The new Mississippi River Bridge is the first bridge built connecting downtown St. Louis and southwestern Illinois in more than 40 years. Currently, the only urban interstate bridge between Illinois and Missouri is the Poplar Street Bridge, known locally as the PSB. The PSB is one of two bridges in the United States that carry three interstates. By relocating one interstate (I-70) from the Poplar Street Bridge to the new Mississippi River Bridge, drivers will experience less congestion, fewer crashes and less unnecessary fuel use. Learn about the project, and stay up-to-date by checking this site regularly and subscribing to our e-mail updates and social networking tools. The bridge should be open to traffic in 2014.

  • Mississippi River Bridge

    July 6, 2010 update: Work has begun on the Missouri Approach.  Crews have demolished some of the buildings on the right of way and are currently working on constructing drilled shafts for the foundations for the approach.

    Work on the main span has been somewhat slow due to the river levels.  When the Mississippi is at 28 feet (two feet below flood stage) crews are usually pulled off the river.  When crews have been able to work on the river, they have been drilling into the bedrock for the supports for the bridge.

    Illinois has awarded the contract for the Illinois Approach and is currently working on plans for a groundbreaking.
