Lewis and Clark Viaduct I-70 westbound closure

Work will soon begin on a portion of the Lewis and Clark Viaduct.  Closures for the reconstruction of the I-70 westbound bridge are scheduled to take place on Feb. 2 at 10 p.m.  Temporary closures to install traffic control equipment may take place leading up to the two-year westbound closures.

Westbound I-70 will be closed from the Broadway interchange in Kansas City, Missouri westward to the connections in downtown Kansas City, Kansas for the duration of the two-year construction period.  The main detour route will use I-670 westbound and the secondary route will use I-35 southbound.  To detour to Kansas City, Kansas, please use the Central Avenue Exit form I-670.  To facilitate traffic operations using the Central Avenue Exit:

  • A second lane will be added to the 3rd St./James St. Exit Ramp from I-70.
  • Temporary signals will be added to tow intersections.

In preparation for the reconstruction, demolition of the Lewis & Clark Viaduct westbound lanes is tentatively scheduled for early March, a date and time are yet to be determined.  The public will be able to watch the demolition on KDOT's Facebook page at

While it is not anticipated that traffic control will change once the project beings, please continue to check the Kansas City Metro lane closures on the KDOT website for more details.
