Colorado State Highway 392

The route begins at US 287 south of Fort Collins, Colorado along Robert Benson Lake. The road then intersects CR 13 and CR 11, where it briefly enters Redmond before entering the Fossil Creek Regional Open Space, along which is located the Fossil Creek Reservoir. As the road continues eastward through the park, it becomes the southern boundary before interchanging with I-25.[2]

East of I-25, the road briefly continues through farmland before crossing the Larimer/Weld county line. Afterwards, it meets SH 257 in Windsor, nearing Windsor Lake. The road then continues through rectangularly shaped fields before meeting US 85, where it curves slightly southeastward. As the road continues eastward, the fields become circular, and the road turns slightly northeastward. The surrounding land then becomes barren grassland as the road abruptly turns eastward then sharply northward.[2] The road then meets its terminus several miles later at SH 14 in Briggsdale.

The route was established in 1949, where it began at SH 257 in Windsor and continued east to Barnesville. The road was then paved entirely by 1958, then extended to today's I-25 in 1960. The route was then extended east to Cornish; this section was paved by 1977. The route was then extended to its current terminus at Briggsdale at SH 14 the next year. In 1994, the section east of SH 37 (now deleted) was deleted.[3]

In 2007, the section between US 287 and I-25 was added to SH 392 and the formerly deleted section was readded.[3]
