Every year, Rocky Mountain National Park snowplow operators begin plowing Trail Ridge Road in mid-April. Trail Ridge Road is the highest continuous paved road in the United States - reaching 12,183 feet in elevation. Crews from the west side of the park and crews from the east side of the park move along the road and eventually meet near the Alpine Visitor Center. Park plow operators normally encounter drifts from 18 to 22 feet and are accustomed to plowing the same section of road over and over. Trail Ridge Road was completed in 1932. The earliest the road has opened was on May 7, 2002; the latest June 26, 1943. In 2011, the road opened on June 6.
Due to recent spring snowstorms park plow operators are experiencing significant drifts and snowpack at high elevations along the road. More snow is forecast for next week.
