Weekend Travel Forecast

March 24-26, 2017

Traffic volume is not expected to be high this weekend, but weather will very likely play a part in I-70 travel.  Heavy snow is forecasted Thursday to Friday morning, and there is a chance for snow Saturday night through Sunday.  Allow for extra travel time, and check your tire tread before you leave home!  

Friday WB – Traffic volume will not be heavy, but roads could be snow packed and/or icy resulting in slow travel.

Saturday WB – Last year there were 20 minute delays on this date between 7:00 and 8:00 a.m.  It will be best to avoid the 6:30 a.m.-11:00 a.m. timeframe.

Saturday EB- On this Saturday last year, there were eastbound delays of 30 minutes between Noon and 6:00 p.m., mostly due to bad road conditions.  Weather could also cause delays this Saturday.

Sunday EB – Congestion should not be significant this afternoon, but avoid the 11:00 a.m.-5:00 p.m. timeframe when traffic is the most likely to occur. Check the road conditions at CoTrip.org before you jump on I-70!

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.
