Want to try carpooling? Use TreadShare, a carpool app that connects drivers and passengers heading in the same direction in Colorado so they can share a route and split the associated costs.

Pro tip: If you decide to go to the mountains, use GoI70’s travel forecast to help plan the best time to travel to avoid traffic!


Pegasus is the Colorado Department of Transportation’s express shuttle that began providing passenger service in May 2022. Pegasus departs year-round from behind Union Station, at 17th Street and Wewatta Street with stops at the Denver Federal Center in Lakewood, Idaho Springs, Frisco, Vail and Avon. A Pegasus shuttle seats up to 11 people, is wheelchair accessible, and equipped with USB ports, power outlets, and Wi-Fi. Each vehicle also has bike racks and ski/snowboard containers. A one-way fare from Denver to Frisco is only $13.

One fully booked Pegasus shuttle is the equivalent of removing six two-person vehicles, helping to alleviate traffic congestion during peak travel times. And Pegasus can utilize the Express Lanes on weekends, when traffic nearly doubles. The service allows passengers to connect to local transit providers at each stop, making it easier than ever to get to the mountains car-free (and carefree!). Ticketing and schedule information is available online at

Snowstang (Winter Only)
Five Colorado ski areas opted to partner with the Colorado Department of Transportation on their ski bus service, Snowstang. This service allows riders to avoid winter driving and provides the ability to relax instead of dealing with traffic. Plus, Snowstang drops riders off right at the lift/gondola for quicker access to the slopes! Through this partnership, Snowstang limits greenhouse gas emissions, takes vehicles off I-70 and stress off overwhelmed resort parking lots allowing more customers to hit the slopes.

Pick up locations are Denver Union Station, Denver Federal Center-Lakewood and the Dinosaur Lots at the I-70 Morrison Exit. Arapahoe Basin Ski Area, Copper Mountain Resort, Loveland Ski Resort, Steamboat Ski Resort, and the Town of Breckenridge and Breckenridge Ski Resort are all Snowstang
