Hotels in Vail often tell guests they don’t need to bring their cars, especially during ski season. Over the past few years, alternatives have grown to taking the family car to the high country.

The I-70 Coalition, a nonprofit group of governments and businesses along the Interstate 70 mountain corridor, has for several years been urging visitors to change the times they drive from the mountains to the city. The coalition has also recently launched a web-based tool for travelers to explore alternatives: goI70.com/transit

The website directs visitors to a number of alternatives, including:

• Bustang: The bus service run by the Colorado Department of Transportation was started as a way to get people to the Denver area from different parts of the state. The success of that Denver-focused service led the transportation department to launch weekend service from the city to outlying areas, including the mountains.

According to the I-70 Coalition, Bustang ridership grew more than 50 percent from 2016 to 2017.

That growth “is exciting,” I-70 Coalition executive director Margaret Bowes said. “It shows people are more willing to take transit.”
