Last Blast for Summer Traffic

Aug. 31, 2018

DENVER—Drivers can anticipate heavy traffic in many areas across the state this Labor Day weekend.

All CDOT construction projects will be suspended statewide at noon today to reduce potential traffic delays. The only exception is for emergency operations. Projects will resume their regular schedules on Tuesday, Sept. 4.

Heavier-than-normal weekend traffic is expected on I-25 along the Front Range and on I-70 west of Denver. More traffic than normal will travel westbound I-70 today and Saturday, and eastbound I-70 on Labor Day—especially between Summit County and the Denver area. Traffic traditionally is heaviest from late morning through early evening.
