I-70 traffic is quite predictable unless affected by weather or accidents. Plan to avoid peak travel times, and enjoy a delay-free trip along I-70.  Our weekend travel forecast is updated every Thursday afternoon.

NOVEMBER 22 - 24

No major storms but fresh snow is expected to sprinkle the mountains through Friday afternoon. Roads could be slippery and traffic volumes could be higher as we move another week closer to the winter season. Brush up on the new Traction Law, pay close attention to the weather, and check CoTrip.org to learn more about what is happening on the road.

Friday WB – Moderate traffic volume with 15-20 minute delays possible during the peak times of 5pm to 7pm. Morning flurries could stretch through the afternoon leading to slippery roads. Keep your eye on CoTrip.org and stay prepared.

Saturday WB – Moderate traffic volume with 20 - 30 minute delays possible during peak times of 6:30am to 10:30am. Roads should be dry, but a little bit of fresh snow should bring more skiers/snowboarders to the corridor than in recent weeks and cause slower travel. 

Saturday EB – Light-to-moderate traffic volume with possible slow-downs from 2pm to 5pm. No adverse weather and no significant volume related delays expected.

​​​​Sunday WB – Light-to-moderate traffic volume expected with possible slow-downs from 6:30am to 9am but no significant delays expected.

Sunday EB – Moderate traffic volume expected with 20 to 30 minute delays possible during peak times of 2pm to 6pm.

I-70 Preview


Mild and dry on Monday and Tuesday. Snow returns on Tuesday night and continues through Friday, with the best chances for heavy snow coming on Wednesday, Thursday, and again on Friday. This will create wet, slick, and snow-packed road surfaces through Friday night. Expect slower travel speeds from Wednesday morning through Friday night. After a dry weekend, we should have plenty to keep an eye on through Thanksgiving week.

Weather, Road Conditions & Accidents - these are impossible to predict and can escalate the level and duration of delays dramatically. Before you travel, check one of the real time information resources!

Holiday Weekends - when a national holiday falls on a Monday, you can count on Monday afternoon eastbound traffic to mimic a typical Sunday pattern, but with potentially more volume. On the flip side, the Sunday of holiday weekends tends to have slightly less congestion than usual.

Safety Metering - Safety metering eastbound at the Eisenhower Tunnel goes into effect during periods of particularly high traffic volume. This process is in place to ensure traffic flows safely and freely through the tunnel. Expect eastbound delays when metering is in effect.

Mountain Express Lane - This eastbound express lane provides a more reliable travel time to those willing to pay the toll.  Get the ExpressToll pass to pay the posted toll rate.  Those without a pass will be billed the posted rate plus a service charge.  More info at ExpressToll.com

With just a bit of planning travelers can enjoy More Mountains and Less Traffic. Below is the typical winter weekend traffic pattern.  Although there are heavy volumes around the holidays, the most significant of delays are limited to January and February.

Friday Westbound - Light to moderate traffic is possible from about 3:30-8:00 p.m.

Saturday Westbound - If you want to avoid skier traffic, plan to leave the Front Range no later than 6:00 a.m. Traffic is consistently at its worst right around 8:00 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 much lower in volume than Sunday. Many Saturdays see very little congestion but it varies by weekend.  To play it safe, avoid the 2:00 - 6:00 p.m timeframe. 

Sunday Westbound - Traffic due to volume is not typically an issue westbound on Sunday mornings.  To play it safe, avoid the 7:00 a.m. to 10:00 a.m. timeframe.

Sunday Eastbound - I-70 traffic starts to build as early as 11:00 a.m.  The peak of the traffic occurs between 3:00-6:00 and drops off soon after 7:00 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!
