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.

Detours

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.
