The Missouri Department of Transportation will close Interstate 70 from the Missouri 291/Interstate-470 interchange to the Interstate 435 interchange this weekend so crews can demolish the old I-435 bridges above I-70 as part of ongoing reconstruction.

The highway will be closed from 10 p.m. Friday, to approximately 5 a.m., Monday. Westbound traffic that didn’t already exit will be rerouted to southbound M-291/I-470. Eastbound I-70 traffic will be rerouted to southbound I-435.

Crews will begin reducing lanes on westbound I-70 from the I-470 interchange to I-435, as well as eastbound I-70 at I-435, at about 8 p.m. Friday. Beginning at 9 p.m., crews will begin closing all on ramps to westbound I-70 between the two interchanges. Those include: M-291/I-470, Lee's Summit Road, Noland Road, U.S. 40 and Blue Ridge Cutoff. The on-ramp from Manchester Trafficway to eastbound I-70 will also be closed at that time, as will the loop ramp from southbound M-291 to eastbound I-70.
