State Route 303 (SR 303), named Warren Avenue, begins at an intersection with Burwell Street, signed as SR 304, north of the Puget Sound Naval Shipyard in Bremerton. Warren Avenue travels north through Bremerton and serves Olympic College before crossing the Port Washington Narrows on the Warren Avenue Bridge. The highway intersects Clare Avenue and Callahan Drive in a partial cloverleaf and diamond interchange.[3] In East Bremerton, the roadway becomes Wheaton Way and continues north through suburban areas and intersects Sheridan Road, a spur route of SR 303 prior to 1991.[2][4] SR 303 passes View Ridge Elementary and Sylvan Way, the former SR 306 serving Illahee State Park, before leaving Bremerton. The highway turns west at an intersection with its former route, the Brownsville Highway, and becomes a grade-separated freeway named Waaga Way. The freeway intersects Central Valley Road in a partial cloverleaf interchange and turns northwest to intersect Ridgetop Boulevard in a diamond interchange.[5][6] Waaga Way travels around the Kitsap Mall and interchanges with Silverdale Way before intersecting SR 3 in Silverdale, continuing as Kitsap Mall Boulevard into the city center.[7][8][9] The entire highway is part of the National Highway System and was used by a daily average of 42,000 vehicles in 2011.[10][11]
