SH 392 begins at a
T intersection with US 287 on the southern
city limits of Fort Collins in Larimer County, southwest of Robert Benson Lake. From its western terminus, SH 392 heads east as Carpenter Road to cross
County Road 13 (South Lemay Avenue) and
County Road 11 (South Timberline Road), 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 a
diamond interchange at (Exit 262) with
Interstate 25/
U.S. Route 87 (I-25/US 87). East of I-25/US 87, the SH 392 briefly continues through farmland before crossing the Larimer–Weld county line. Afterwards, it begins a brief
concurrency with
SH 257 within
Windsor and passing just south of
Windsor Lake. SH 392 then continues through rectangularly shaped fields before crossing
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. The SH 392 then meets its terminus several miles later at
SH 14 on the northwestern edge of
Briggsdale. The roadway continues north as
County Road 77. ==History==
