Winter Traffic Patterns

(early Dec-mid April. Based on historical data.)

Avoid some very specific time frames and you can enjoy More Mountains, Less Traffic on I-70 this winter.  Below is the typical winter weekend traffic pattern.

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!

Weather, Road Conditions & Accidents 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.

Metering - Traffic metering goes into effect during very high volume times and can occur at multiple I-70 eastbound on-ramps and/or on the Eisenhower Johnson Tunnel 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.
