Traffic due to volume shouldn’t be an issue between now and mid-June.   As always, check one of CDOT’s real time information sources before you jump on I-70 to see if there are construction or weather-related delays.

Winter Traffic Patterns

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

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

Saturday and Sunday Westbound - Moderate traffic from about 6:30 a.m. to 11:00 a.m. with the peak around 7:30-8:00 a.m. Sunday morning WB traffic is typically lighter than Saturday morning, or non existent.

Saturday EB - Traffic builds around 2:30 p.m., peaks around 4:00-5:00 and drops dramatically after 7:00 p.m. Expect heavy congestion.

Sunday EB - 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 very heavy traffic.

Other factors: Metering - Traffic metering goes into effect during very high volume times at the Johnson/Eisenhower Tunnels.  This process involves controlling the flow of traffic eastbound into the Eisenhower Tunnel, so traffic does not back up in the tunnel.

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 minimal congestion.

Weather & Accidents - can escalate the level and duration of congestion dramatically.
