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.
Arcata, California
U.S. Route 101 extends north and south and bisects the city. The downtown has several overcrossings; Arcata is considered a fairly walkable community. State Route 299 connects to U.S. Route 101 at the northern end of Arcata. SR 299 begins at this point and extends easterly towards Weaverville, Redding, Alturas, and Nevada. SR 255 Connects to U.S. Route 101 at the southern end of Arcata on Samoa Blvd. and to the west of US-101 passes through Manila. Bridge access (left at first controlled intersection) leads to Eureka through Woodley island and Indian island (using three bridges) ending on 4th (south 101) and 5th (north 101) streets in Eureka, CA. Used as an alternate route to the US-101, its speed limit is though, unlike the speed on Highway 101 – which from the Bayside cutoff to Gallagher lane north 101 and x street south 101 is due to a safety corridor.
