Work will soon begin on a portion of the Lewis and Clark Viaduct. Temporary closures to allow for the installation of traffic control signage for the reconstruction of the I-70 westbound bridge will take place February 1 through February 4. The full two-year closure will begin on February 4.

Permanent Closures

Sunday, February 4 at 5:00 AM to a tentative date of December 31, 2019:  I-70 westbound will be closed past Broadway Boulevard (in Missouri northwest corner of the downtown loop) to 3rd St. In Kansas City, Kansas, ramps from Broadway Boulevard, Beardsley Road, and I-35 to I-70 westbound (in Missouri) will be closed.  Ramps from I-70 westbound (in Kansas) to Minnesota Avenue, Washington Boulevard, and Fairfax Trafficway will be closed.

After the traffic control measures over the weekend of February 3 and 4 are complete, Broadway and I-35 southbound will be accessible from I-70 westbound throughout the duration of the two-year construction.  


The main detour route will travel around the downtown loop or come up I-35 northbound to use I-670 westbound.  The secondary route will use I-35 southbound to the 27th Street exit.  To detour to Kansas City, Kansas, please use the Central Avenue Exit from I-670 westbound.  To facilitate traffic operations using the Central Avenue Exit, a second lane will be added to the 3rd Street/James Street Exit Ramp from I-70.  Temporary signals will be added to the two intersections.
