ROCKY MOUNTAIN NATIONAL PARK, Colo. (CBS4) — The phrase doesn’t carry the weight of a more popular one.

But, yes…..spring is coming.

Proof can be found in the annual trek toward the top of Trail Ridge Road undertaken by snowplow operators on either side of the Continental Divide.

Those drivers began their task in mid-April and continue today.

Trail Ridge Road through Rocky Mountain National Park is the highest continuous paved road in the United States (at 12,183 feet in elevation). That means, of course, a tremendous amount of winter’s accumulation must be cleared from the pavement before travelers can traverse its length and enjoy its views.

Crews regularly encounter snowdrifts up to 22 feet deep and “are accustomed to plowing the same section of road over and over” due to repeated snowfall, stated RMNP spokesperson Kyle Patterson.

One such storm system is just days away.

This, to end a winter season that already brought a number and severity of avalanches that reached historic proportions in Colorado.

The goal is always to open the highway in time for Memorial Day, traditionally the beginning of the tourism season.
