State Route 117 (SR 117) is a short, 1.40-mile (2.25 km) long state highway located entirely within Port Angeles, the county seat of Clallam County, in the U.S. state of Washington. The short roadway, named the Tumwater Truck Route, serves the waterfront of Port Angeles and intersects two streets and crosses under another street on a short bridge. Beginning at an interchange with U.S. Route 101 (US 101), the highway travels northeast to terminate at Marine Drive. SR 117 was first established in 1991, but a road parallel to the current roadway had existed since 1966.
