Weekend Travel Forecast

February 5-7, 2016

Weather should not be a travel factor this weekend.

Friday WB - Traffic is possible from 4:00-8:30 p.m. 

Saturday WB – Expect heavy traffic from 6:30 a.m.-Noon, with the peak delay time of 30-60 minutes extra travel time occurring around 8:00 a.m.  Leave by 6:00 a.m. to get ahead of the crowds.

Saturday EB- Traffic is likely to build by 2:00 and peak around 5:00 pm.  Plan to leave after 7:00pm to avoid peak traffic.  Delays on this day in recent years ranged from 20-30 minutes extra travel time.

Sunday WB – Traffic due to volume is unlikely.

Sunday EB – With the big game, traffic volume should be lighter than a typical Sunday.  Last year, traffic started at 11:00 a.m. and built slowly up until 5:00 p.m.  Delays resulted in 30 minutes extra travel time last year.

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.
