Slow-Moving Storm Systems to Impact Weekend Travel Along I-70 Mountain Corridor

STATEWIDE—The first of three waves of winter weather has hit the I-70 mountain corridor west of Denver. The National Weather Service (NWS) has forecast two more storm fronts through the state over the weekend and into early next week—which could bring more than a foot of snow to some high mountain passes.

"The storm systems will likely result in the return of snow-packed and icy roads for I-70 from Georgetown to Vail, and may require chain and traction laws," said Patrick Chavez, CDOT I-70 Mountain Corridor manager. "We'd like to remind travelers heading to ski resorts and winter events to be prepared for slower traffic and longer commute times because of the snowy conditions. Due to traction concerns during heavy snowfall, CDOT may implement its safety metering system, located just east of Silverthorne this weekend, to help alleviate traffic congestion."

Safety Metering

Safety metering is triggered by high traffic, accidents or adverse weather. The metering prevents traffic back-ups. There are two types of metering to be aware of:

  1. Continuous-Flow Safety Metering occurs on the eastbound approach to the Eisenhower Tunnel. An alternating red and green stoplight cycles every four to eight seconds to keep traffic moving consistently through the tunnel, while traffic on the tunnel's east side slowly dissipates.

  2. On-Ramp Safety Metering occurs at eastbound on-ramps at Copper Mountain, Frisco, Silverthorne and Loveland. This type of metering may be more familiar, occurring on highway and interstate on-ramps throughout most metro areas.
