Weekend Travel Forecast
May 27-30, 2016
This weekend marks the unofficial beginning of summer, but fortunately NOT the beginning of I-70 summer congestion. Memorial Day weekend traffic on the I-70 mountain corridor is typically spread out enough that volume and congestion should not be much of an issue. Eastbound afternoon delays typically don’t rear their ugly heads until we get into June. To play it safe, if you travel eastbound on Sunday and Monday, don't jump on I-70 until after 6:00 p.m.
As you plan summer trips that take you through the I-70 mountain corridor, reference the typical summer traffic pattern below, and plan to avoid the peak travel times.
Enjoy your holiday weekend!

Summer Traffic Patterns
The I-70 mountain corridor sees higher traffic volumes in the summer than it does in the winter. Some weekend congestion can be expected from Memorial Day through Labor Day, and the information below can help you plan your trip around that traffic. September weekends see a similar pattern of congestion, but delays are not as significant.
Friday WB– There are occasionally moderate delays heading westbound on Friday evenings. Traffic may build between 2:00-3:00 p.m., peak around 4:00 p.m., and end between 6:00-7:00 p.m. These delays might mean an added 20 minutes to a trip from Golden to Vail.
Saturday and Sunday WB – traffic is well-distributed westbound on weekend mornings. The exception to this is the Saturday of Labor Day Weekend where moderate delays may occur from 10:00 am-3:00 pm.
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 EB – According to historical data, eastbound traffic starts to build around 11:00 a.m. The peak of traffic is consistently at 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.
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 far 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- In the summer, weather plays a larger 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.
