Last Blast for Summer Traffic

September 4, 2015 - Colorado Statewide - DENVER – The Colorado Department of Transportation (CDOT) is reminding drivers to anticipate heavy traffic in many areas of the state due to the number of events and activities taking place over the Labor Day weekend.

All CDOT construction projects will be suspended statewide by late Friday afternoon to reduce potential delays.  The only exception is for emergency operations.  Projects resume their regular schedule on Tuesday, September 8. 

          Heavier than normal weekend traffic is expected on Interstate 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 so CDOT advises traveling before 11 a.m. or after 6 p.m.

Friday, August 29, 2014




Saturday, August 30, 2014

CDOT is keeping the Mount Evans Highway (State Highway 5) open after this weekend.  It normally closes the day after Labor Day from Summit Lake to the top, per an agreement between CDOT and the U.S. Forest Service.  This year, it will close in late September or early October or due to adverse weather.  Since construction required a highway closure for several weeks earlier this summer, CDOT is keeping it open for several more weeks if weather permits. 

Other seasonal roadways – State Highway 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.
