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.

JANUARY 18-21, 2019

This will be a busy weekend on I-70 due to the Martin Luther King Holiday.  Be prepared for snow and winter driving conditions Friday and Friday evening.  Roads will likely remain snow packed and icy into Saturday morning.

Friday WB – Winter weather might result in slow travel throughout the day and evening.  Traffic volumes will increase from 1:00-9:00 p.m. with delays at their peak between 4:00 and 6:30 p.m.

Saturday WB - Expect heavy traffic from 6:00 a.m.-1:00 p.m., with the peak occurring between 8:00-9:00 a.m.  Last year traffic resulted in an additional 1 hour of travel time between C470 and Frisco.  Leave the Denver area by 6:00 a.m. if you want to get ahead of the volume! 

Sunday WB - Expect traffic between 7:00 a.m. and 11:30 a.m. with up to 40 minutes extra travel time possible.

Monday WB – Light traffic is possible between 7:00 a.m. and 10:00 a.m.

Saturday EB- The last three years, traffic started to build around 3:00 p.m., but there were only 10-20 minute delays.  Plan to leave the high country after 7:00 p.m. to avoid the rush back to the metro area.

Sunday EB –Based on this same weekend last year, traffic will build around Noon, peak between 4:00-5:00 and drop off by 7:00 pm.

Monday EB - On three day holiday weekends, Mondays mimic the typical Sunday traffic pattern.   In recent years, traffic started to build as early as 11:00 a.m. and continued until 6:30 p.m.  Last year the heaviest traffic occurred between 2:00 and 5:00 p.m.  Your best bet is to check CoTrip.org to learn what is happening on the road before you travel.    

Enjoy the long holiday weekend!

(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.
