DENVER — Two years after Bustang first launched, the number of people catching a ride keeps growing.

The bus service connects Denver to Fort Collins, Colorado Springs and the mountain towns along Interstate 70.

Bustang also provides special services to home Broncos games and the RamsRoute from Colorado State University in Fort Collins to Denver on Friday and Sunday nights during the school year.

COPIRG, a public interest research group, said overall ridership jumped 52 percent in its second year. The largest increase was along the mountain route, where ridership surged 77 percent.

The Colorado Department of Transportation is planning to expand Bustang in the coming year by adding weekend service, new stops and more buses on existing routes during the workweek.
