State Route 166 (SR 166) is a 5.13-mile (8.26 km) long state highway serving the city of Port Orchard within Kitsap County in the U.S. state of Washington. The highway begins at an interchange with SR 16 west of Port Orchard and travels along the Sinclair Inlet to Downtown Port Orchard and ends as Mile Hill Drive at Whitter Avenue near the eastern city limits. SR 166 was originally a branch of State Road 14 and later Primary State Highway 14 (PSH 14) before being designated as SR 160 after the 1964 highway renumbering. SR 160 was moved south in 1993 and the old alignment through Port Orchard became SR 166, which was extended in 2010 to the eastern city limits.
