Weekend Travel Forecast

November 24-29, 2015

Historically, traffic is spread out during the Thanksgiving holiday week and weekend, resulting in only light to moderate delays.  Plan for snowy weather throughout the entire corridor on Thanksgiving Day.  There is a chance of snow Friday-Sunday west of Eisenhower Tunnel.

Winter Traffic Patterns


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.

Holiday Weekends – when a national holiday falls on a Monday, you can count on Monday afternoon EB traffic to mimic a typical Sunday pattern, but with potentially more volume. On the flip side, the Sunday of holiday weekends tends to have far less than normal congestion.

Safety Metering – Safety metering at the on ramps in Frisco, Silverthorne goes into effect during very high volume times.  This process controls the flow of traffic eastbound into the Eisenhower Tunnel, so traffic does not back up in the tunnel.
