The Missouri Department of Transportation will have various lane and ramp closures at the I-435 and I-70 interchange this week starting Monday, Sept. 14. Motorists should expect delays in the area. All work is weather permitting.

  • Eastbound and westbound I-70 will be reduced to ONE LANE at I-435 for bridge construction OVERNIGHT on Monday, Sept. 14, from 7 p.m. to 5 a.m. the following morning.
  • The ramp from southbound I-435 to eastbound I-70, as well as the ramp from eastbound I-70 to Blue Ridge Cutoff, will be CLOSED for bridge construction OVERNIGHT on Tuesday, Sept. 15, from 8 p.m. until 5 a.m. the following morning.
  • Northbound I-435 will be reduced to ONE LANE at I-70 for pavement marking reconfiguration OVERNIGHT on Wednesday, Sept. 16, from 8 p.m. to 5 a.m. the following morning.
    • Once this work is completed, northbound I-435 traffic will be switched over to their new lanes on the brand new northbound I-435 bridge 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. Crews recently opened the new southbound I-435 ramp to eastbound I-70, as well as the new northbound I-435 ramp to westbound I-70. Construction is still in progress for the I-70 loop ramps and the northbound I-435 bridges over I-70.

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.

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.
