U.S. Route 101
The nearly highway's northern terminus is in Tumwater, Washington: the route remains along the Olympic Peninsula's coastal perimeter west, north, and east; the northernmost point on the highway is in Port Angeles. The southern terminus of US 101 is in Los Angeles at the East Los Angeles Interchange, the world's busiest freeway interchange.
California State Route 271
State Route 271 (SR 271) is a state highway in northern California, USA. It is a former routing of U.S. Route 101 (US 101), now reduced to being a frontage road for that route in discontiguous segments. It also connects with Route 1 just before that route's terminus with US 101 in Leggett. Its appeal now is that while US Highway 101 stays mostly in second growth redwoods, State Route 271 travels through several old growth redwood groves. It is now most commonly used as a scenic alternate.
