Weather, Road Conditions & Accidents are impossible to predict and can escalate the level and duration of delays dramatically. Check CDOT’s CoTrip.org before you travel.

Colorado’s Traction Law is in effect Sept 1-May 31, regardless of current weather conditions. Learn if your tires meet the Traction Law specifications here.

The Mountain Express Lanes are open on the weekends and holidays to provide a faster and more reliable travel time between Denver and the mountains. Get the Express Toll pass to pay the posted toll rate. Those without a pass will be billed the posted rate plus a service charge. Order the pass at ExpressToll.com.

Holiday Weekends – When a national holiday falls on a Monday, you can count on Monday afternoon eastbound traffic similar to a typical Sunday pattern, but with higher volume.

Metering – Traffic metering goes into effect during very high-volume times at the Eisenhower Johnson Tunnel on the eastbound approach.  Metering controls the flow of traffic eastbound towards the Eisenhower Tunnel so traffic does not back up in the tunnel, causing potential safety issues.


With just a bit of planning, travelers can enjoy More Mountains, Less Traffic. Below is the typical winter weekend traffic pattern. The heaviest volumes on the I-70 mountain corridor occur around the holidays and on weekends in January and February, but plan for weekend traffic during the entire ski season. Check the detailed weekend Travel Forecast at the top of this page, posted each Thursday.

Friday Westbound – Traffic volumes are moderate from approximately 2:00-7:00 p.m. with congestion the most likely to occur in the Floyd Hill area.

Friday Eastbound – A relatively new occurrence, as more daytrippers ski on Friday, there is often slowing 2:00-4:00 p.m.

Saturday Westbound – To beat the traffic, plan to leave the Front Range by 6:00 a.m. Traffic is consistently at its highest between 8:00 a.m. and 10:00 a.m., resulting in up to one hour of additional travel time. Speeds return to normal soon after Noon. 

Saturday Eastbound – Saturday eastbound traffic tends to be lower in volume than Sunday. Avoid the 2:00-5:00 p.m. timeframe. 

Sunday Westbound – Traffic is less of an issue westbound on Sunday mornings but delays are possible in the 7:00 a.m. to 10:30 a.m. timeframe.

Sunday Eastbound – I-70 traffic starts to build as early as 11:30 a.m.  The peak of the traffic occurs between 3:00-6:00 and drops off soon after 8:00 pm. Expect heavy traffic. To avoid the jam, stay in the mountains for dinner, or spend Sunday night and head back to work or school Monday morning.  GoI70.com Peak time Deals provide incentives to avoid peak travel times.
