Travel directions

The SH 139.

SH 139 begins just south of the village of Loma at a junction with Interstate 70, not far east of the Utah state border and 15 miles northwest of the city of Grand Junction. SH 139 heads north through the village of Loma where it crosses old US 6/50. The road heads north out the wide valley of the Colorado River. The road passes through lonely mountain areas, there are no other places between the start and end point. The road takes you over the 2,520-foot Douglas Pass, one of the trickier passes in Colorado, especially on the south side. The road then descends north to Rangely, which is 1,600 meters above sea level, where SH 139 ends at SH 64.


SH 139 is one of Colorado’s original 1920s state highways. The road has always run between Loma and Rangely, but originally started in Loma itself on US 6. Between 1954 and 1964, the road did not have state highway status. The road was largely paved in the first half of the 1970s, from Loma to Douglas Pass in 1972 and on to Rangely in 1975. In about 1972, SH 139 was extended south to the then newly constructed Interstate 70.

Traffic intensities

Every day 2,000 vehicles in Loma and approximately 900 vehicles continue to Rangely.

State Route 14, commonly known as State Highway 14 or SH 14 is a state route in the U.S. state of Colorado. The road forms an east-west route through the north of the state, through the Rocky Mountains and across the High Plains. SH 14 runs from US 40 at Muddy Pass via Fort Collins to Sterling. At 381 kilometers in length, it is the longest state highway in Colorado.

Travel directions

The 3,132 meter high Cameron Pass.

The Poudre Canyon west of Fort Collins.

Rocky Mountains

SH 14 begins at an intersection with US 40 at 2,674 foot Muddy Pass. The road first heads in a northeasterly direction, first through a wide valley, which turns around Walden into a large basin nearly 50 kilometers wide. This is a dry area. In the village of Walden one crosses the SH 125. From Walden, the road heads southeast through the basin, gradually ascending to the 3,132-foot-high Cameron Pass. The mountains around are almost 4,000 meters high.

From Cameron Pass, a long winding route follows through a series of canyons to the lowlands near Fort Collins. No other major roads are crossed on this route, and there are no significant places on the route up to the High Plains. The landscape goes from high mountains to canyons to finally the lowlands. The part through the Poudre Canyon has few high mountains in the immediate vicinity, the Rocky Mountains here merge less abruptly into the High Plains. This part of SH 14 is a time consuming route.

High Plains

Once you reach the High Plains, SH 14 crosses US 287 into Fort Collins, a fast-growing city 100 miles north of Denver. The portion through Fort Collins has five lanes of traffic including the center turn lane, but the road is limited through densely populated areas, although SH 14 does run through downtown, but Fort Collins has grown mainly south and west. The part between downtown and the junction with Interstate 25 is a 2×2 divided highway.

East of Fort Collins, SH 14 leads through an alternation of agricultural and rangeland, well north of Greeley. The single-lane road leads over the rolling steppe, most places on this part of the route are very small. SH 14 eventually terminates in the town of Sterling on US 6, near Interstate 76.


SH 14 was one of Colorado’s original 19 cross-state highways from the early 1920s. The road has always started at Muddy Pass, but originally ran further east from Sterling to the border with the state of Nebraska. This became part of US 6 from 1926. The road was paved between Fort Collins and Ault in the early 1930s. The rest of the route between Ault and Sterling was paved in the 1940s, although the easternmost section at Sterling was not paved until the late 1940s.

The route through the Rocky Mountains was longer unpaved. This part was asphalted in the 1950s and 1960s. In 1963, the section between Muddy Pass and Walden was paved, but it wasn’t until 1972 before the route over Cameron Pass was paved.

SH 14 does not have much passing importance, partly because of the sparsely populated part of the northern Rocky Mountains in Colorado, and the lack of major tourist attractions in this part of the mountains. The eastern section between Fort Collins and Sterling has some regional importance, partly due to the growth of the city of Fort Collins.

The route over Cameron Pass is considered one of the best sheltered high passes in the Rocky Mountains in Colorado, and is therefore less often closed. However, because the mountain pass only connects few areas with many inhabitants, very little traffic uses it.

Traffic intensities

Every day, 1,000 vehicles drive between Muddy Pass and Walden, 700 to 800 vehicles over Cameron Pass and 1,300 to 2,200 vehicles through the Poudre Canyon. The Fort Collins section has 26,000 to 40,000 vehicles between downtown and I-25. This is one of the busiest stretches of Colorado state highway outside Denver. This drops to 7,000 vehicles between Fort Collins and Ault and 1,500 to 3,000 vehicles further to Sterling.
