State Route 435 (SR 435) is a state highway in Sullivan County, Tennessee, that provides access to the Bristol Caverns.[1]
SR 435 begins at an intersection with US 421 and SR 394. It heads in southeasterly direction and passes Bristol Caverns and finally comes to an end at US 421/SR 44. The entire route is a rural 2-lane highway as it does follow the former alignment of US 421 before the current 4-lane divided highway was built to the south.[1]
