I-70 closure in downtown Topeka to begin next month for PQV project

The Kansas Department of Transportation has scheduled the full closure of I-70 in downtown Topeka to begin in June as part of the Polk-Quincy Viaduct (PQV) project. Additional short-term closures on local roadways are also planned.

Starting Monday, June 8, all lanes of I-70 between Topeka Boulevard and 8th Avenue are scheduled to close until December. During the closure, project work will focus on removing the existing viaduct and completing the new structures. Construction will also continue on the new I-70 lanes and local street network.

The closure's designated detour will direct I-70 through traffic to I-470. Access to and from the downtown area can be made via the I-70 ramps at MacVicar Avenue, Topeka Boulevard, 8th Avenue and 10th Avenue. Kansas Avenue and Topeka Boulevard will also be open.

Motorists are encouraged to review the I-470 detour and other alternative routes prior to this closure.

Removal of the existing viaduct will start on Tuesday, June 9. Temporary closures will occur on portions of Kansas Avenue, Topeka Boulevard and I-70. Motorists should plan for the following:

  • Tuesday, June 9, and Wednesday, June 10, from 7 p.m. to 5 a.m.: Kansas Avenue will be closed between 1st and 3rd streets. A detour will be marked on 3rd Street, Topeka Boulevard and N.W. Morse Street.
  • Friday, June 12, from 11 p.m. until Monday, June 15, at 4 a.m.: Topeka Boulevard will be closed between 1st and 3rd streets. Through traffic can follow the detour on 3rd Street, Kansas Avenue and N.W. Morse Street. During this closure:
    • Southbound Topeka Boulevard will have access to the westbound I-70 on-ramp. Northbound Topeka Boulevard will be directed to 6th Street and MacVicar Avenue to access westbound I-70.
    • Eastbound I-70 will also be closed starting at MacVicar Avenue. Eastbound motorists can follow the local detour: MacVicar Avenue to 6th Avenue to Topeka Boulevard to the 10th Avenue I-70 on-ramp.

Additional reductions, closures and other traffic impacts will be necessary as the project progresses.

All project work and traffic changes are conditions permitting and subject to change.
