Winter Traffic Patterns

(October through April)

I-70 is congestion-free the majority of the time, and with just a bit of planning travelers can enjoy More Mountains. Less Traffic.   Below is the typical winter weekend traffic pattern.

Friday Westbound - Light to moderate traffic is likely from about 4:00-9:00 p.m.

Saturday Westbound - Traffic can be expected from about 6:30 a.m. to 11:00 a.m. with the peak traffic occurring around 8:00 a.m.

Sunday Westbound - Sunday morning WB traffic is consistently lighter than Saturday morning, and sometimes non-existent.  To play it safe, avoid the 7:00 a.m. to 10:00 a.m. timeframe.

Saturday Eastbound - Traffic typically builds around 2:00 p.m., peaks around 4:00-5:00 and drops dramatically after 7:00 p.m. Expect congestion.

Sunday Eastbound - I-70 starts to fill up earlier than it does on Saturday, as early as 1:00 p.m.  Traffic peaks around 4:00-5:00 and drops off soon after 7:00 pm.  Expect heavy traffic.

This Travel Forecast is based on historical traffic data.  Please note that weather, road conditions and accidents are impossible to predict and can have significant impacts on I-70 travel.

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 minimal congestion, making it an ideal day to travel.

Other factors: 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.
