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.
SR 166 begins as Bay Street in a partial interchange with SR 16 west of Port Orchard at the mouth of Anderson Creek, where it empties into the Sinclair Inlet. Bay Street travels northeast along the south shore of the Sinclair Inlet into Downtown Port Orchard, passing a foot ferry to Bremerton and the Port Orchard Library. The highway crosses over Blackjack Creek and turns south onto Bethel Avenue, passing between Sunset Lane Cemetery and South Kitsap Discovery Alternative High School before a roundabout, where SR 166 turns east onto Mile Hill Drive. The highway ends as Mile Hill Drive at an intersection with Whitter Avenue near the eastern city limits of Port Orchard.
