Sunny weekend expected along the I-70 Mountain Corridor. While we are not yet in peak Summer traffic, heavy volumes have begun earlier this year than in past seasons. Nice weather coupled with one of the high country's biggest events, the GoPro Mountain Games, will lead to some delays this weekend. If traveling eastbound on Sunday, delays can be avoided by waiting until after 5pm to leave the high country. Keep your eye on COtrip.org to know before you go!
Friday WB - Moderate traffic with delays of up to 15 to 20 minutes possible between 1pm and 6pm.
Saturday WB - Moderate traffic with delays of up to 15 to 20 minutes possible between 10am and 3pm.
Saturday EB - Light traffic with no volume related delays expected.
Sunday WB - Light traffic with no volume related delays expected.
Sunday EB - Heavy traffic with delays of 30 to 45 minutes expected between 1pm and 6pm. If you are attending the GoPro Mountain Games and want to avoid peak traffic, wait until the end of the day before hopping on I-70!

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.
Safety Metering – Safety metering eastbound at the Eisenhower Tunnel goes into effect during high volume times. This process controls the flow of traffic eastbound into the Eisenhower Tunnel, so traffic does not back up in the tunnel. Expect eastbound delays when metering is in effect.
Weather - In the summer, weather plays a large factor in traveler behavior. If rain showers move in early in the day, expect drivers to head back to the Front Range early as well.
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.
(June through mid-September. Based on historical data.)
During the shoulder seasons of early April through the beginning of June, and mid-September through mid-December, traffic on I-70 is light, and volume related delays are not common. Following that, and depending on weather (rain, snow melt, and wildfires), routine Summer traffic begins to build in early June and lasts into mid-September. Thankfully, I-70 traffic IS PREDICTABLE and that means that by shifting your travel times, I-70 traffic is AVOIDABLE; the forecast below is based on years of traffic data and analysis, and can help you avoid the worst of it!
Friday Westbound - There are occasionally moderate delays heading westbound on Friday evenings. Traffic may build between Noon-3:00 p.m., peak around 4:00 p.m., and end between 6:00-7:00 p.m. Delays during this timeframe might mean an added 20 minutes to a trip from C470 to Frisco.
Saturday and Sunday Westbound - On Saturdays, you might experience congestion from 10:00-2:00 p.m. Get an earlier start to avoid traffic. There are rarely westbound delays on Sundays.
Saturday Eastbound - Saturday eastbound traffic tends to be much lower in volume than Sunday but slow traffic might be encountered mid-afternoon/early evening.
Sunday Eastbound - According to historical data, eastbound traffic starts to build around 11:00 a.m. The peak of traffic is consistently between 3:00 and 4:00 pm all summer long. With folks trying to enjoy every bit of daylight in the mountains, the traffic typically doesn’t diminish until approximately 7:00-8:00 p.m. To avoid the traffic, consider staying in the mountains for dinner, or spend Sunday night and head back to the Front Range early Monday morning.
