Granby to Rocky Mountain National ParkEdit

The route begins in Granby at US 40. It then follows the Colorado River Valley near Granby Lake and enters Arapaho National Recreational Area.[3]

Trail Ridge RoadEdit

After entering Rocky Mountain National Park in Colorado's Front Range,[citation needed] US 34 follows the North Fork Colorado River through Kawuneeche Valley. It passes over Milner Pass and reaches the Alpine Visitor Center. Then it continues east, passing its highest point at 12,183 feet[4] near Fall River Pass. It exits the park at US 36 at Deer Ridge Junction.

US 34 here is the highest continuous highway in the United States.[4]

This section of US 34 requires a $30 national park entrance fee, making this segment into a toll road.

Estes Park to LovelandEdit

From here, it passes by Estes Park as Eisenhower Boulevard, has a business route and enters Loveland, becoming a four-lane expressway. Here, it intersects I-25 and U.S. Highway 287.

Greeley to Nebraska borderEdit

At Greeley, it passes by U.S. Highway 85 in a complex interchange[1] and U.S. 34 Business, and crosses the South Platte River. It also has an interchange with SH 257.[5] From here, it is no longer an expressway. It intersects SH 144 and SH 39, then joins I-76 at Wiggins. It leaves, and follows the North Fork Republican River east into Nebraska, where it intersects SH 71, SH 52, SH 63, SH 61, SH 59, and U.S. Highway 385.


Parts of the route were originally designated as US 38. US 34 was extended into Colorado in 1939.[1]
