Trail Ridge Road is the highest continuous paved highway in the United States. Known appropriately as the “Highway to the Sky”.


The name “Trail Ridge Road” is derived from its proximity to historic pathways used by native peoples to cross the Rocky Mountains. Arapahoe Indians called the trail located on the ridge as “taienbaa” (“Where the Children Walked”) because it was so steep that children could not be carried and had to walk.


Trail Ridge Road was designed to replace Fall River Road, which was inadequate for modern motor travel as soon as it opened in 1920. Trail Ridge Road made motor travel easier with gentle grades, broader curves, and a greater variety of scenic experiences. The sunny, exposed location reduces snow accumulations and allows Trail Ridge Road to open earlier then its shady predecessor.


Trail Ridge Road was constructed between 1926 and 1932 through the collective efforts of the National Park Service and the Bureau of Public roads (now the Federal Highway Administration). Construction Crews had to contend with imposing terrain, harsh weather, short working seasons and stringent design criteria. The new route was to ensure that the road would “lie lightly on the land”, displaying the areas scenic diversity and have minimal impact on the natural environment. Trail Ridge Road opened in July 1932, providing motorists with access to impressive, views, memorable wildlife viewing opportunities and spectacular high mountain terrain.
