State Route 303 (SR 303) is a 9.27-mile (14.92 km) state highway in Kitsap County, located in the U.S. state of Washington. The highway connects SR 304 in Bremerton to an interchange with SR 3 in Silverdale. SR 303 crosses the Port Washington Narrows on the Warren Avenue Bridge in Bremerton and becomes a grade-separated freeway bypass of Silverdale. The route has existed as unpaved roads since the 1930s and was signed as Secondary State Highway 21B (SSH 21B) in 1937. SSH 21B connected Bremerton to Keyport and had a branch to Illahee State Park added in 1961. After the 1964 highway renumbering, SSH 21B became SR 303 from Bremerton to Keyport and SR 306 from Bremerton to Illahee State Park. SR 303 was shortened in 1971, to include SR 308, and in 1991, re-routing the highway onto the new Silverdale freeway. SR 303 also had a spur route in Bremerton that served the Manette Bridge until 1991.
