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.

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.

[2] East of I-25/US 87, the SH 392 briefly continues through farmland before crossing the Larimer–Weld county line.

SH 392 then continues through rectangularly shaped fields before crossing US 85, where it curves slightly southeastward.

The surrounding land then becomes barren grassland as the road abruptly turns eastward then sharply northward.
