The Missouri Department of Transportation will has rescheduled various ramp closures the week of Monday, July 27. The new dates are below. Following these closures, crews will begin to open NEW ramps within the I-435 and I-70 partial turbine interchange. This is a new design and is the first of its kind in the Kansas City region. This design replaces the previous and less traditional left side exit ramps and will help improve safety and provide congestion relief at the interchange. All work and openings are weather permitting.

Wednesday, July 29

  • The ramp from eastbound I-70 to southbound I-435 will be CLOSED for pavement marking work OVERNIGHT on Wednesday, July 29, from 8 p.m. to 5 a.m. the following morning.
  • Once this work is completed (sometime early Thursday, July 30), crews plan to OPEN the all new ramp from eastbound I-70 Blue Ridge Cutoff. This ramp had been previously closed for construction work.

Thursday, July 30

  • The ramp from southbound I-435 to westbound I-70 and to U.S. 40 Highway will be CLOSED for pavement marking work OVERNIGHT on Thursday, July 30, from 8 p.m. to 5 a.m. the following morning.
  • Once this work is completed (sometime early Friday, July 31), crews plan to OPEN the all new ramp from southbound I-435 to eastbound I-70, eastbound Blue Ridge Cutoff, and westbound I-70.
    • Motorists traveling southbound on I-435 will be able to exit right to merge onto either direction of I-70.
    • Westbound traffic will continue straight onto westbound I-70.
    • Eastbound traffic will loop around the partial turbine design to merge onto eastbound I-70.
    • Motorists will also be able to exit to eastbound Blue Ridge Cutoff.

Construction is still in progress for the I-70 loop ramps and the northbound I-435 bridges over I-70. This project began construction in spring 2019 and while the majority of construction is scheduled to be completed by this fall, motorists can expect to see various lane closures in the area through Dec. 2020. Project improvements include full bridge replacements, removal of left exits, improvements to loop ramp configuration, and congestion relief. 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.


For potential impacts to traffic, please review KC Scout cameras at or consult our real-time traffic partner, WAZE.

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.
