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.
Crescent City, California
Highway access is provided by U.S. Route 101, which runs directly through the city, connecting the Oregon Coast to the north and Eureka to the south. U.S. Route 199 begins just north of Crescent City and heads northeast to Grants Pass, Oregon. The junction of U.S. Routes 101 and 199 is one of only two junctions of two U.S. Routes in California, the other being the junction of U.S. Routes 6 and 395 in Bishop.
