Travel Forecast & Tips


Fortunately, I-70 is congestion free the majority of the time and traffic is quite predictable, weather and accidents withstanding. Plan to avoid peak travel times, and enjoy a delay-free trip along I-70.  Our weekend travel forecast is updated every Thursday afternoon.

Weekend Travel Forecast
April 24-27

Traffic due to volume shouldn’t be an issue between now and mid-June; however, snow is expected for this Sunday so make sure your car is still ready for winter conditions!   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.

*The Travel Forecast is based on historical data, along with an estimation of how weather, construction, public events and other factors might impact travel.

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.
