State Route 392 (SR 392) is a state highway and bypass around downtown Crossville in Cumberland County in the U.S. state of Tennessee.[1]
SR 392 begins on the northwestern edge of downtown Crossville at an intersection with US 127/SR 28 (N Main Street). It proceeds southwest as an undivided 2-lane highway with a center turn lane to an intersection with US 70/SR 1 (West Avenue), where it widens to a 4-lane undivided highway and turns southeast. The highway passes by several homes and businesses before narrowing to 2 lanes after its short concurrency with SR 101 (Lantana Road). SR 392 continues southeast through some neighborhoods to another intersection with US 127/SR 28 (S Main Street). The highway then gains a center turn lane and curves northeast, passing through some more rural areas before coming to an end at an intersection with US 70/SR 1/SR 101 (Highway 70/Peavine Road) at a roundabout, just south of SR 101's interchange with I-40 (Exit 322).
The entire route of SR 392 is known as Miller Avenue.[1]
