The weather should be dry most of the weekend with the possibility of heavy snow Sunday evening.

Friday WB – Slow traffic could be encountered from 4:30-7:45 p.m. 

Saturday WB - Moderate to heavy traffic is likely from 6:15 - 11:00 a.m. with the slowest travel occurring around 8:00 a.m. 

Saturday EB- Expect some slowing from 3:00-5:30 p.m.

Sunday WB – There were no delays on this day the past three years, but light volume is still possible between 6:30 a.m. and 9:30 a.m.

Sunday EB –Last year, there were delays from 3:00-7:00 p.m.  Snow is in the forecast for late Sunday.

Monday WB – No congestion-related delays are expected but be prepared for winter driving.

Monday EB – Expect heavy traffic on this day!  Last year there were delays from 11:00 a.m.-7:00 p.m. and resulted in 45 minutes of extra travel time between Frisco and C470.  Your best bet is to enjoy the mountains later into the day and head home after 7:00 p.m.

Winter Traffic Patterns

(October-May)

Every Thursday, GoI70.com posts a travel forecast specific to the coming weekend, but below is the typical winter traffic pattern.

Friday WB– There are occasionally moderate delays heading westbound in the 3:30-8:00 p.m. timeframe.

Saturday WB– If you want to avoid traffic, plan to leave the Front Range by 6:00 a.m. sharp.  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 EB- Saturday eastbound traffic tends to be much lower in volume than Sunday. It is usually spread out enough that, barring an accident, there is not much congestion.

Sunday WB – Traffic due to volume is not typically an issue westbound on Sunday mornings.

Sunday EB – According to historical data, eastbound traffic starts to build around Noon. The peak of traffic occurs in the 3:00-6:00 p.m. timeframe. The Mountain Express Lane has alleviated some of the eastbound congestion, but travelers will still experience delays most afternoons.  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.  GoI70.com Peak Time Deals provide incentives to avoid the peak travel times!

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 less than normal congestion.

Safety Metering – Safety metering 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.  It is a safety, not a traffic control, measure.  Expect delays when metering is in effect.

Weather- Obviously, winter weather will result in slower speeds.  And all it takes is one minor “fender bender” to snarl traffic for hours.  Please be sure your tires are winter-ready, and take it slow.
