Route description
SR 419 begins in the Cumberland Homesteads community at an intersection with US 127/SR 28.

The highway then leaves the park and winds its way west through farmland and rural areas to come to an end just south of Crossville at an intersection with SR 101. The entire route of SR 419 is a two-lane highway and lies atop the Cumberland Plateau.
