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

• May 2, 2012: Construction on the two river towers is proceeding well. Both towers have reached more than 300 feet and crews have been installing the steel anchor boxes onto the towers. Crews should complete the 400-foot towers for the project later this spring and then start attaching the cables and the framework for the driving surface. Construction work for the Illinois Approach is proceeding well. Crews have completed installation of all the girders on the Illinois Approach and have started the initial work to form up the driving surface on the project.
  
  The Missouri Approach is complete.

• Missouri North I-70 Interchange

  May 2, 2012 :Work continues well on the Missouri North interchange. Crews are working just off Interstate 70 to build the foundations needed for the ramps and bridges for the new interchange with I-70. Crews are also working on the north side of Cass Avenue to complete the roadwork and connections there.
  There are several planned road closures anticipated for this project over the remainder of the year. 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.

  Illinois I-70 Connection

  May 2, 2012 : Grading and other construction continues for the relocated I-70 corridor and relocated Illinois Route 3 interchange. Archeology work continues along the corridor as well, and is projected to be completed in early summer. Construction on the new ramps between the tri-level and relocated I-70 is well underway.

  

• Illinois Tri-Level Interchange (I-55/64/70)

  May 2, 2012 : Construction projects along the relocated I-70 corridor and the tri-level interchange are moving along well. After opening the 15th Street bridge over I-64, crews removed the 9th and 10th Street bridges over Interstate 64 in late March to prepare for the new interchange. The new bridge on 9th Street should be completed by summer 2013.
