Friday travel will be very tricky with snow and high winds almost guaranteed. Plan for very slow travel and possible road closures. Dry conditions will prevail Saturday morning with more mountain snow forecasted for Saturday afternoon. The forecast for Sunday calls for partly cloudy skies.

Friday WB – Expect snowy roads, poor visibility and very slow mountain travel. Volumes will be highest from 2:00-6:00 p.m. but winter driving conditions will be the biggest travel factor.

Saturday WB – Traffic will be heavy between 7:00 a.m. and 11:00 a.m., with delays in the neighborhood of 15 minutes.

Sunday WB – No volume-related delays are anticipated.

Saturday EB –Traffic could we thick between 2:00 and 5:00 p.m., and with afternoon snow in the forecast, travel will be slow.

Sunday EB – Traffic will start to build around 11:00 a.m. and continue until approximately 6:00 p.m. resulting in about 20 minutes of extra travel time between Silverthorne and C470.

TIPS FOR I-70 MOUNTAIN TRAVEL

  • Avoid the Peak Travel Times.  If heading eastbound on Saturday or Sunday, plan to leave the mountains after 7:00 p.m. Check the weekend and holiday Travel Forecast.
  • ​​​Check the road and traffic conditions before you travel. 
  • Check out the Peak Time Deals local businesses offer to help you avoid peak travel times.
  • Spend a Sunday night in the mountains and head to work or school early Monday morning.
  • Prepare for I-70 mountain driving conditions.  Understand the Traction & Chain Laws.
  • Create or join a carpool. 
  • Consider taking a bus, train, van or carpool to the mountains and leave the driving to someone else. 

IMPORTANT INFO TO KNOW 

Colorado’s Traction Law is in effect Sept 1-May 31, regardless of current weather conditions. Learn if your tires meet the Traction Law specifications here.

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 similar to 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 at the Eisenhower Johnson Tunnel on the 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.

Mountain Express Lane - The Mountain Express Lanes provide a more reliable travel time to those willing to pay the toll.  Get the ExpressToll pass to pay the posted toll rate. Those without a pass will be billed the posted rate plus a service charge.  More info at ExpressToll.com

TYPICAL WINTER TRAFFIC PATTERNS

With just a bit of planning travelers can enjoy More Mountains, Less Traffic. Below is the typical winter weekend traffic pattern.The heaviest volumes on the I-70 mountain corridor occur around the holidays and on weekends in January and February, but plan for weekend traffic during the entire ski season. Check the detailed weekend Travel Forecast at the top of this page, posted each Thursday.

Friday Westbound - Moderate traffic is likely from about 11:00 a.m.-8:00 p.m.  The heaviest volumes occur late afternoon/early evening and mostly in the Floyd Hill area.

Saturday Westbound - If you want to avoid skier traffic, plan to leave the Front Range by 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 less of an issue westbound on Sunday mornings. To play it safe, avoid the 7:00 a.m. to 10:30 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 8:00 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.
