I-70 traffic is quite predictable unless affected by weather or accidents. Plan to avoid peak travel times, and enjoy a delay-free trip along I-70.  Our weekend travel forecast is updated every Thursday afternoon.

MARCH 15-17, 2019

The dust is settling from these winter storms and the high country (I-70 included) should be sunny, dry, and warm this weekend. Historically, these mid to late March, spring break weeks have traffic demand spread more evenly through the week and weekend. This being said, we have some bluebird days in store for you, and could see a little more traffic than expected. We have a positive forecast this weekend, so keep your fingers crossed! As always – better safe than sorry, and remember to keep your eye on the weather, keep watching avalanche conditions, and visit CoTrip.org to learn more about what is happening on the road before you travel!

Friday WB – Moderate-to-heavy traffic Friday afternoon and evening. No significant delays expected, but peak travel times will be from 5pm through 7pm.

Saturday WB – Heavier traffic expected, but delays should be under 45 minutes. Peak traffic will be from 6am through 10am.

Saturday EB – Moderate traffic volume and minimal delays expected, however peak traffic will be between 3pm and 6pm.

Sunday WB – Moderate-to-heavy traffic with clear roads and the potential for smooth sailing.

Sunday EB – Heaviest weekend traffic expected from 3pm through 6pm. Delays are possible but not expected to be longer than 45 minutes.

(mid-December to mid April. Based on historical data.)

Friday Westbound - Light to moderate traffic is possible from about 3:30-8:00 p.m.

Saturday Westbound - If you want to avoid skier traffic, plan to leave the Front Range no later than 6:00 a.m. Traffic is consistently at its worst right around 8:00 a.m. resulting in up to one hour of additional travel time. Speeds return to normal soon after Noon. 

Saturday Eastbound - Saturday eastbound traffic tends to be much lower in volume than Sunday. Many Saturdays see very little congestion but it varies by weekend.  To play it safe, avoid the 2:00 - 6:00 p.m timeframe. 

Sunday Westbound - Traffic due to volume is not typically an issue westbound on Sunday mornings.  To play it safe, avoid the 7:00 a.m. to 10:00 a.m. timeframe.

Sunday Eastbound - I-70 traffic starts to build as early as 11:00 a.m.  The peak of the traffic occurs between 3:00-6:00 and drops off soon after 7:00 pm.  Expect heavy traffic. To avoid the jam, stay in the mountains for dinner, or spend Sunday night and head back to work or school Monday morning.  GoI70.com Peak Time Deals provide incentives to avoid peak travel times!

Weather, Road Conditions & Accidents are impossible to predict and can escalate the level and duration of delays dramatically. Before you travel, check one of the real time information resources!

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 slightly less congestion than usual.

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.
