The Colorado Department of Transportation on Saturday suspended its Bustang and Outrider bus service for all routes throughout the state until at least April 11 amid the effort to mitigate the effects of the novel coronavirus.

The lines, which provided bus service between Fort Collins, Grand Junction, Colorado Springs and Denver, among other routes, could be reopened after April 11, or the closure could be extended, according to a press release from the agency.

“Avoiding travel between cities and regions is an important part of limiting the spread of COVID-19,” the press release said.

The intercity cancellations do not affect local bus service.
