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.

• Mississippi River Bridge

• January 12, 2012: Construction on the two river towers is proceeding well. Both towers have reached the 200 foot level, and are roughly half completed. They should be complete in late spring, and then crews will start attaching the cables and the framework for the driving surface.The Missouri Approach is complete. Construction work for the Illinois Approach is proceeding well. Crews have completed all the foundation work for the approach and have started placing the girders for the bridge. The driving surface will be placed on the girders soon.

• Missouri North I-70 Interchange

  January 12, 2012 : The Cass Avenue project has been completed and is open to traffic. This winter, the Howard and 9th bridge was demolished and removed, and crews closed the express lanes to complete foundation work for the new ramps between I-70, Cass Avenue and the new bridge. The express lanes are expected to close for about six weeks in the spring to complete the ramp construction work. Crews have also closed one lane on eastbound I-70 between St. Louis Avenue and Broadway, as well as the 11th Street ramp to eastbound I-70 to increase safety for drivers and for construction crews working on the interchange.
