Total CLOSURE of I-70 at I-435 for Bridge Demolition Work Feb. 21-24

JACKSON COUNTY– The Missouri Department of Transportation will have a COMPLETE CLOSURE of Interstate 70 in both directions at I-435 in Kansas City, MO beginning at 10 p.m. on Friday, Feb. 21, until approximately 5 a.m. on Monday, Feb. 24. This closure is for the demolition of the old I-435 bridges over I-70. This is part of the new partial turbine interchange construction at I-435 and I-70. All work is weather permitting.

  • Crews will begin reducing I-70 to ONE LANE in both directions near I-435 at approximately 8 p.m. on Friday, Feb. 21. Motorists can expect various lane closures during this time.
  • I-70 will be closed entirely near I-435 at approximately 10 p.m. on Friday, Feb. 21 until approximately 5 a.m. on Monday, Feb. 24.
    • Eastbound I-70 will be reduced to one lane at Manchester Trafficway and traffic that has not already exited I-70 will be detoured off of I-70 at the ramp to southbound I-435.
      • Motorists needing to continue to eastbound I-70 are advised to take I-470 around the closure.
    • Westbound I-70 will be reduced to one lane at Blue Ridge Cutoff. All traffic that has not already exited I-70 will be routed onto northbound I-435.
      • Motorists needing to continue to westbound I-70 are advised to follow northbound I-435, turn around at 23rd Street, and follow southbound I-435 back onto westbound I-70.

This work will have major impacts to traffic. Motorists MUST follow the signed suggested detours using I-470 and I-435 or find an alternate route. For potential impacts to traffic, please review KC Scout cameras at or consult our real-time traffic partner, WAZE.

This is all part of a new interchange design being built at I-435 and I-70. The new design will be a partial turbine configuration. Improvements include full bridge replacements, removal of left exits, improvements to loop ramp configuration, and congestion relief. This project will have significant impacts on traffic for two full construction seasons and is scheduled to be complete by Dec. 2020. For more information about this project, visit our website. Please be patient and considerate to your fellow motorists. Use the zipper merge and take turns at merge points.  Please remember that all work zones are NO PHONE ZONES. Buckle up. Phone down. Arrive Alive.

Motorists are reminded to slow down and pay attention while driving in work zones. Not all work zones look alike. Work zones can be moving operations, such as striping, patching or mowing. They can also be short term, temporary lane closures to make quick repairs or remove debris from the roadway.
