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.

FEBRUARY 19 - 21

This weekend, expect moderate-to-heavy traffic volumes on I-70. While there will be fresh snow to play in, drawing many to the corridor; and weather will impact travel conditions on Saturday afternoon through Sunday morning - we do not expect it to be a unusually high traffic volume weekend. Make sure you're in compliance with the Traction Law, and that you keep your eye on Cotrip.org to know before you go!!

Friday WB - Moderate-to-heavy traffic expected from 4pm through 7pm with delays of 30 minutes or so expected. Quick snow showers are forecasted for earlier in the day, but I-70 should be dry by the afternoon's peak travel times.

Saturday WB - Heavy traffic from 5:45am through 11am with delays of 45 minutes or more possible during the worst expected travel times of 7am through 9am. The highway should be dry prior to afternoon snowfall. 

Saturday EB - Heavy snow is expected to start mid-day and last through Sunday morning. Volume related delays of up to 30 minutes are possible from 2:30pm through 6pm. Keep your eyes on the weather!

Sunday WB - Heavy traffic expected with delays of up to 30 minutes from 6am through 10am. Travel times will depend on when the snowing stops. As of now, snow is expected to stop well before the 6am rush begins.  

​​​Sunday EB - Heavy traffic expected from Noon through 7pm with delays of up to 45 minutes or longer. Worst travel conditions will likely last from 2pm through 6pm. 

*The GoI70.com Travel Forecast is based on historical data, along with an estimation of how weather, construction, public events and other factors might impact travel.

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!
