Willow Creek Pass

Willow Creek Pass is located to the north of Granby, CO, traversing betweenGrand County and Jackson County. This pass runs north-south through the Rabbit Ears Range, over a section of the Continental Divide where the divide briefly run east-west towards Steamboat Springs.

The summit of Willow Creek Pass is located below 10,000 feet, and the road is considered an easy drive compared to roads like Loveland Pass or Independence Pass. This results in a more dependable travel route that doesn’t have a lot of closures during the winter.

The closest nearby paved mountain passes over the divide are Muddy Pass and Rabbit Ears Pass to the west, and Milner Pass to the east.

The photo to the right shows Parkview Mountain, located to the west of Highway 125, right along the divide near Willow Creek Pass.

Parkview Mountain is the large snowcapped mountain to the west. Radial Mountain is on the opposite side of this pass to the east. Far off to the north/northeast, you can see the Medicine Bow Mountains. To the north/northwest, the Park Range can be seen far in the distance. These are all subranges of the Rocky Mountains.

Alternate Routes – A combo of HWY 14 and HWY 40 will take you over the divide to the west of Willow Creek Pass, going over Muddy Pass instead. This route can act as an alternative route between Granby and the northern side of the Continental Divide. That combo of paved highways is open year-round.

Willow Creek Pass History

The first mention of Willow Creek Pass that has been found in Colorado’s newspapers is from The Colorado Miner in 1876. At this time, the pass was still merely a hiking trail that was used by hunters, trappers, and recreational users.

There was a petition for a wagon road over the pass in the year 1900, and construction of the first roadway over Willow Creek Pass began in November 1904. The construction was first led by H.C. Riddle and F.E. Holdredge, and the road was opened for the first time in July 1905.1, 2

This was considered a county road at the time. A contract to build a state road over the pass was awarded to R.W McQueary of Granby in October of 1909.3 The state road (likely just an improved version of the existing road in this case) was completed by July 1910, and an automobile could be driven over Willow Creek Pass from Rand to Granby in 2 hours and 30 minutes.4 This drive can be done in about 45 minutes now.

The roadway was officially designated as Colorado State Highway 125 in 1923, when the CO state highway numbering system was created.

The road was not able to stay opened year-round during the first half of the 20th century. There were steady improvements throughout the 1920s and 30s, but this was still a dirt road at the time.5, 6, 7

1928 – The Bureau of Public Roads awarded a contract to complete $60k of grading and drainage work on the pass.8

1930 – It was reported that the US Forest Service was working on the highway in 1930, and in 1931 the work was completed on what was referred to as the Willow Creek Pass forest highway. It was designated as Highway 24 of the Colorado Highway System. This was essentially just a series of improvements and a new name to go along with the existing names.9, 10

1946 – A project to modernize the highway began in 1946 when a contract was awarded to improve and oil a 13-mile section of the road. This section extended from Rand to approx. 1 mile south of Willow Creek Pass. Work on this section was completed by 1950. Next, a base layer and bituminous surface (paving) was applied to the remaining 20.8-mile section of highway to the south. This section was located between US HWY 40 near Granby, and the point where the existing oil surface began near the southern side of Willow Creek Pass.11
