Denver – The Colorado Department of Transportation is reminding drivers to expect additional traffic in many areas of the state due to the numerous events and recreational activities taking place over the Labor Day weekend.

Beginning at noon on Friday, CDOT is suspending all construction projects to reduce potential traffic delays. The only exception is for emergency operations. Projects can resume their regular schedule on Tuesday, Sept. 5.

Heavier than normal traffic should be anticipated over the holiday weekend along the Front Range and on Interstate 70 west of Denver. Traffic on I-70 is at its peak primarily from mid-morning until early evening on Friday, and from early morning to mid-afternoon on Saturday. Eastbound I-70 traffic will be at its highest on Labor Day from mid-morning to late afternoon, especially from Eagle and Summit counties to the Denver area.

Other seasonal roadways – CO. 82 over Independence Pass between Twin Lakes and Aspen and Trail Ridge Road through Rocky Mountain National Park – remain open through the fall until adverse weather requires a full closure for the winter.

Drivers can get the latest information on the status of the state’s roadways by checking or by calling 511. Specific information regarding Interstate 70 is available at:
Please be aware that Colorado’s new Move-Over Law requires drivers to move over or slow down when they come upon first responder, maintenance, passenger, and Safety Patrol vehicles stopped on the shoulder.
