Holiday Weekends - when a national holiday falls on a Monday, you can count on Monday afternoon eastbound traffic to mimic 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.
Safety Metering - Safety metering eastbound at the Eisenhower Tunnel goes into effect during periods of particularly high traffic volume. This process is in place to ensure traffic flows safely and freely through the tunnel. Expect eastbound delays when metering is in effect.
Mountain Express Lane - This eastbound express lane provides 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.

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 Westbound - 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 Westbound - Significant delays are not typical but slowdowns are possible from mid-morning through mid-afternoon.
Saturday Eastbound - 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 Westbound - Traffic is well-distributed westbound on weekend mornings. Slowdowns and minor delays can be expected between 10:00 a.m. and 1:00 p.m.
Sunday Eastbound - 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.
