It also connects with State Route 1 just before that route's terminus with US 101 in Leggett. After US 101 was realigned, SR 271 was reduced to being a frontage road in discontinuous segments. While US 101 stays mostly in second growth redwoods, SR 271 is used as a scenic alternate through several old growth redwood groves.
