The St. Louis Region / Connecting America’s Roadways

St. Louis boasts four interstates and a high-priority corridor that connects the area to locations North, East, South and West, along with an interstate loop that provides easy travel around the city and connects to large distribution parks in Southwestern Illinois.

  • I-44
  • I-55
  • I-64
  • I-70
  • Avenue of the Saints (a four-lane route between St. Louis and Minneapolis/St. Paul)
  • I-270
  • I-255
  • I-170
  • I-370

The regional freeway system has much lower congestion than other similar sized U.S. urban areas according to the Texas Transportation Institute. In fact, in 2012, the St. Louis MSA had the lowest Travel Time Index of the 25 largest U.S. metro areas.

The region recently worked collaboratively to build the new $670 million I-70 Mississippi River bridge that connects St. Louis and Southwestern Illinois. This new bridge has expanded the area’s roadway capacity by 20%.
