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.

JANUARY 24 - 26

A combination of the X Games and the International Snow Sculpture Championships could lead to a perfect storm on I-70 this weekend. Though there is a slight chance for slippery conditions Friday morning, the road should be pretty dry through the weekend. Volume will be high though, so make sure you pack your patience and allow for extra travel time. Last year was a nightmare on local roads, so if you end up visiting Summit or Pitkin County for these events, make sure you carpool up to the high country, and then take the Summit Stage or RFTA to get around. Comply with the Traction Law and keep your eye on Cotrip.org to know before you go!

Friday WB - Moderate to heavy traffic volume from 3pm through 7pm with delays of up to 30 minutes during the peak travel times of 5pm through 6:30pm. Roads could be slippery in the morning but should be dry by the afternoon/evening rush.  

Saturday WB - Very heavy traffic volume with delays of an hour or more possible during the peak travel times of 6am through noon. Leave before 6am to beat the rush!

Saturday EB - Moderate traffic volume with delays of around 15 minutes expected from 1:30pm through 6pm. No major delays expected but traffic will be heaviest between 2pm and 5pm.

Sunday WB - Moderate to heavy traffic volume with delays of 20 to 40 minutes expected during the peak travel times of 6am through 10:30am. 

Sunday EB - Heavy traffic volume with delays of up to 45  minutes or more possible from 1pm through 6pm, peak travel times are expected to occur between 2pm and 5pm.

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!
