A fast-moving vegetation fire has prompted the closure of U.S. Highway 6 between mile-markers 77 and 83, from Parachute to Rulison. Evacuation orders have been issued for anyone within a 2-mile radius of the fire.

As of 8 p.m. Thursday, the fire is estimated to have burned roughly 310 acres, according to the National Interagency Fire Center. Deputies were first dispatched around 2:40 p.m. to what was initially reported as a 1- to 2-acre fire in heavy brush just off Interstate 70 near mile-marker 79.

Numerous air resources are assisting on scene. While the cause of the fire remains unknown, firefighting efforts are ongoing. Colorado River Fire Rescue is leading fire suppression efforts.

Stowe said Interstate 70 remains open at this time, though smoke is visible throughout Grand Valley.

Motorists are advised to avoid the area and use alternate routes. Emergency personnel are asking the public to follow all evacuation orders and road closures.
