KANSAS CITY, Mo. — The Interstate 435/Interstate 70 interchange project will force a major closure on I-70 starting Sept. 6.

The interstate will be closed in both directions between I-435 and Interstate 470/Route 291 beginning at 9 p.m. on Friday, Sept. 6 through 5 a.m. on Monday, Sept. 9.

During the closure, crews will demolish two more ramps at the I-435/I-70 intersection. They will be tearing down the ramp from southbound I-435 to eastbound I-70 and the ramp from northbound I-435 to westbound I-70.

To ease congestion, MoDOT will be removing the left exits, replacing bridges and improving the loop ramps at the interchange. The full project is expected to be completed by December of 2020.

While the interstate is closed down, MoDOT will be performing other maintenance work in the area including lighting repairs, median barrier wall repairs, drainage work and paving.

Here's what to expect and when:

Thursday, Sept. 5: Crews will close the ramps from northbound I-435 to westbound I-70 and the ramp from southbound I-435 to eastbound I-70 starting at 7 p.m. These ramps will remain closed until approximately spring 2020.

Friday, Sept. 6: Crews will begin reducing lanes of I-70 to just one lane in both directions between I-435 and I-470/Route 291 starting around 7 p.m.

Friday, Sept. 6: At 8 p.m. crews will begin closing all on and off ramps along I-70 between the two major interchanges.

  • Eastbound I-70 ramp closures include:
    • Manchester Trafficway to eastbound I-70.
    • Northbound and southbound I-435 ramps to eastbound I-70.
    • Blue Ridge Cutoff ramp to eastbound I-70.
    • South Highway 40 ramp to eastbound I-70.
    • Blue Ridge Boulevard Ramp to eastbound I-70.
    • Noland Road ramp to eastbound I-70.
    • Lee’s Summit Road ramp to eastbound I-70.
  • Westbound I-70 ramp closures include:
    • Northbound and southbound I-470/Route 291 ramps to westbound I-70.
    • Lee’s Summit Road ramp to westbound I-70.
    • Noland Road ramp to westbound I-70.
    • South Highway 40 ramp to westbound I-70.

Friday, Sept. 6: Then at 9 p.m., I-70 will be completely shut down from I-435 to I-470 until 5 a.m. on Monday, September 9. Southbound Route 291 will be reduced to one lane just north of I-70 to accommodate extra merging traffic.

DETOURS:

  • Eastbound I-70 traffic will be forced to exit using the ramp to southbound I-435.
  • Westbound I-70 traffic will be forced to exit on southbound I-470.

LONG TERM DETOURS:
The ramps from southbound I-435 to eastbound I-70 and northbound I-435 to westbound I-70 are closing until spring 2020.

  • The northbound I-435 ramp to westbound I-70 will be CLOSED beginning at 7 p.m. on Thursday, Sept. 5 until the new ramps are complete in approximately spring 2020.
    • Once the demolition is completed and I-70 has re-opened, drivers needing to access westbound I-70 from northbound I-435 are advised to exit Raytown Road/Stadium Drive, and then turn north and follow Raytown Road 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.
  • The southbound I-435 ramp to eastbound I-70 will be CLOSED long term beginning at 7 p.m. on Thursday, Sept. 5 until the new ramps are complete in approximately spring 2020.
    • Once the demolition is completed and I-70 has re-opened, motorists needing to access eastbound I-70 from southbound I-435 are advised to take the exit ramp to westbound I-70, proceed to the U.S. 40 Highway exit and turn back east.
      • 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.
