U.S. Route 101
U.S. Route 101, or U.S. Highway 101 (US 101) is a north–south United States Numbered Highway that runs through the states of California, Oregon, and Washington, on the West Coast of the United States. It is also known as (The Royal Road) where its route along the southern and central California coast approximates the old trail which linked the Spanish missions, pueblos, and presidios. It merges at some points with California State Route 1 (SR 1).

Following the dangerous Morse Creek S-Curves is a Rest Area and viewpoint at the Deer Park Loop interchange. The road then becomes a divided expressway until it reaches Carlsborg and crosses the Dungeness River. It enters the town of Sequim and turns into a super-two expressway, bypassing the town. East of Sequim, the road turns back into a standard two-lane road and goes to Sequim Bay and then Discovery Bay, where it intersects SR 20 and turns south. After a short distance, US 101 intersects the western end of SR 104. The road then turns south to the town of Quilcene. Exiting Quilcene, the road heads southwest into Olympic National Forest and crosses a pass between Mount Walker and Buck Mountain, after which it proceeds sharply downhill southeast towards Dabob Bay, where it continues following the shore and reaches Hood Canal.
