Route description

SH 9 near Hoosier Pass
SH 9 as it enters the South Park National Heritage Area

State Highway 9 starts at a junction with US 50 west of Cañon City. It heads northwest, following Currant Creek most of the way to Currant Creek Pass where it enters an open area known as South Park. The south fork of the South Platte is crossed as the highway enters Hartsel and a junction with US 24. SH 9 follows US 24 west for 0.5 mi (0.80 km), then splits off to head northwest again. Just south of Fairplay, it joins northbound US 285. At Fairplay SH 9 leaves US 285 to head northwest, following the middle fork of the South Platte most of the way to Hoosier Pass where it crosses the Continental Divide 11,532 ft (3,515 m) above sea level. Switchbacks drop the highway to the Blue River which it follows north through Breckenridge to Dillon Reservoir. The highway goes around the west side of the reservoir, through Frisco and joins I 70 as it heads northeast. At Silverthorne, SH 9 leaves I 70 to continue northwest alongside the Blue River. SH 9 crosses the Colorado River just before its termination at a junction with US 40 in Kremmling.[2]


An original 1923 Colorado state highway, SH 9 originally ran along much of its current route, from Hartsel to Kremmling. In 1939, the highway was extended south past US 50 near Parkdale, continuing south to Cañon City. In 1954, this extension was reverted, and the southern terminus of SH 9 was returned to US 24 at Hartsel. A year later, in 1955, the southern terminus was again modified, and extended to Guffey. In 1957, the highway was again extended southwards, this time to US 50 near Parkdale, where it stands today. The entire road was paved by 1980.[3]

In 2016, the state completed a wildlife crossing project to reduce wildlife-vehicle collisions between Green Mountain Reservoir and Kremmling, including 2 wildlife overpasses and 5 underpasses; the state also widened the road and shoulders.[4][5][6]
