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


(December through March. Based on historical data.)

Depending on snow, resort conditions, (and pandemic) conditions, I-70 typically starts to see routine Winter weekend traffic in early-to-mid December. This is then disrupted from the days before Christmas through the weekend after New Years. Following that, traffic patterns become fairly routine through January and February (with some anomalous long weekends here and there). March is a bit less predictable (typically) due to Spring Break travelers dispersed through the month, and then routine traffic starts to fade through April. Thankfully, I-70 traffic IS AVOIDABLE, and based on years of traffic data and analysis, the information below is reliable and can help you avoid the worst of it!

Friday Westbound - There are typically moderate delays heading westbound on Friday evenings. Traffic may build between 3pm to 4pm, peak around 5pm, and end between 6pm to 7:30pm. These delays might mean an added 20 minutes to a trip from Denver to Vail.

Saturday Westbound - Significant delays of up to 45 minutes or more are expected from 6am through 10am on Saturday mornings. For best results, leave Denver before 6am or after 9:30am. 

Saturday Eastbound - Saturday eastbound traffic tends to be much lower in volume than Sunday. It is usually spread out enough that, barring an accident, there is not much congestion.

Sunday Westbound - Sunday mornings are fairly similar to Saturday mornings, however delays are sometimes slightly (5 to 10 minutes) shorter, and travelers typically leave 15 to 30 minutes later). Delays can be expected from 6:30am through 10:30am. 

Sunday Eastbound - According to historical data, eastbound traffic starts to build around 1:00pm. The weekend's peak of traffic is consistently from 3pm to 5pm all summer long. To avoid the traffic consider staying in the mountains for dinner, or spend Sunday night and head back to the Front Range early Monday morning. GoI70.com Peak time Deals provide incentives to avoid peak travel times!
