Project Status: Find Alternative Routes to go to I-435 West from I-470 East and 71 North. Bridge replacement scheduled to be complete Sept. 15

Find Alternative Routes

MoDOT has posted detours, but encourages motorists to find the best alternative routes for their commute. This interchange will remain closed until repairs can be made.

MoDOT has created detours, but also encourages the 65,000 motorists who use the I-470 movement to I-435 West to find ways to help reduce the expected congestion:

  • Expect delays. Alter your departure time and give yourself plenty of time.
  • Change your work hours or telecommute, when possible.
  • Find alternative routes.  Think of the nearest East-West roadway that can get you to US 71 or I-435.  Keep in mind that 87th Street and Kenneth road are closed due to construction.  Parts of Bannister Road, Red Bridge Road and 150 Highway have lane reductions due to construction.
