Trail Ridge Road
See Map Below


Trail Ridge Road provides spectacular view of the majestic scenery of Rocky Mountain National Park. It is the highest continuous motorway in the United States, with more than eight miles lying above 11,000' and a maximum elevation of 12,183'. The name "Trail Ridge Road" derives from it proximity to historic pathways used by native peoples to cross the Rocky Mountains.

Trail Ridge Road was designed to replace Fall River Road, which proved inadequate for modern motor travel as soon as it opened in 1920. Trail Ridge Road was designed to have more gentle grades, broader curves, and a greater variety of scenic experiences. The sunny, ridge-top location would also reduce snow accumulations and allow Trail Ridge Road to open earlier then its shady, snow-laden predecessor.

Trail Ridge Road was constructed between 1926 and 1932 through the collaborative 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, which were intended to ensure that the road would "lie lightly on the land" displaying the region's rich scenic diversity with 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.

GRADE: The road was designed with a ruling grade generally less than 5% and never exceeding 7%, less that half as steep as the Fall River Road.

TURN RADIUS: Minimum radii for open curves were 100' and 200' on blind curves. Many curves were designed to sweep across but not dominate the landscape.

ROAD WIDTH: Unlike the single-track Fall River Road, Trail Ridge Road was designed as a two-lane with a 22' roadbed and 3' ditches in cut sections.

ELEVATION GIAN: The roadway was largely built into the hillside, elevated on rock fill once it reached tundra. Long continuous curves were used to gain elevation.

PULLOUTS: The commodious stone-wall turnouts, often located on major curves, provided ample space for visitors to take in the views.

A visit to Trail Ridge Road at night:
Two-thirds of the world's population can no longer look upwards at night and see the Milky Way -- a hazy swath of stars that on warm summer nights spans the sky from horizon to horizon. The Milky Way is dimming, not because the end of the Universe is near, but rather as a result of light pollution: the inadvertent illumination of the atmosphere from street lights, outdoor advertising, homes, schools, airports and other sources. Every night billions of bulbs send their energy skyward where microscopic bits of matter -- air molecules, airborne dust, and water vapor droplets -- reflect much of the wasted light back to Earth.

Atop Trail Ridge Road at night you can still see the Milky Way as you are far from the city lights of the Front Range and above almost 50% of the earth's atmosphere that reflects the light pollution. On a clear night take a late evening ride and enjoy one of nature's greatest light shows. Be sure to dress warmly and give your eyes a chance to adjust after you exit your vehicle. Can you find the Big Dipper, North Star, Orion, Sirius (the brightest star) and Virgo. You may have forgotten how many stars your can see: billions and billions.
