Welcome

The $640 million Mississippi River Bridge project is proceeding through design, with construction scheduled to start in early 2010. 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.
