This is part of the new partial turbine interchange at I-435 and I-70. While I-70 is closed, a variety of MoDOT crews will be working along the seven-mile stretch of the closure to complete other much-needed maintenance work including lighting repairs, median barrier wall repairs, drainage work, and paving operations along I-70. All work is weather permitting.

o    Once the demolition is completed and I-70 has re-opened, motorists needing to access westbound I-70 from northbound I-435 are advised to exit Raytown Rd./Stadium Drive, and then turn north and follow Raytown Rd. as it becomes Manchester Trafficway. Motorists should then continue on Manchester Trafficway to U.S. Highway 40. Turn west onto U.S. Highway 40 and follow the detour to the westbound I-70 on-ramp.

§  Through Traffic on Game Days at Arrowhead Stadium:  Due to immense traffic anticipated near the stadiums on game days, motorists needing to access westbound I-70 from northbound I-435 are advised to exit at 23rd Street and make a U-turn under the bridge to southbound I-435.  Motorists should then take the exit from south-bound I-435 to westbound I-70.

§  Through Traffic on Game Days at Arrowhead Stadium: Due to immense traffic anticipated near the stadiums on game days, motorists traveling from southbound I-435 needing to go eastbound on I-70 are still advised to take the exit ramp to westbound I-70, proceed to the U.S. 40 Highway exit and turn back east.

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.
