Trail Ridge Road in Rocky Mountain National Park has closed to through traffic for the season, the National Park Service announced in a press release on Tuesday, November 17.

However, both Trail Ridge Road and Old Fall River Road (which is also closed) will remain open to bicyclists and leashed pets until November 30. After that, they are open to pedestrians only.

'Trail Ridge Road was not designed to be an all season road, with 11 miles above 11,500 feet, few guardrails and no shoulders,' the National Park Service said. 'Winter conditions of drifting snow, high winds and below freezing temperatures often occur above 10,000 feet.'

Typically, the road reopens late May or early June, weather permitting.

Trail Ridge Road is also closed between the Colorado River Trailhead and Grand Lake Entrance to 'all uses,' the National Park Service said. The East Troublesome Fire damaged portions of the park on the west side.
