highway serves as the northern terminus of SR 3 east of the bridge and turns northeast towards Port Gamble, located on the Kitsap Peninsula. SR 104 turns south along the western shore of Port Gamble, the bay the community is named after, and turns southeast to intersect SR 307. The highway continues east from the intersection to Kingston, where it splits into a one-way pair before the designation travels onto the Edmonds–Kingston Ferry. The ferry, operated by Washington State Ferries (WSF), takes approximately 30 minutes to cross across Puget Sound. It departs from Kingston on Appletree Cove and arrives in Edmonds in Snohomish County. WSF operates thirteen round-trip crossings every day. Westbound passengers must pay a $7.70 toll or they may alternately pay with a prepaid Wave2Go card. SR 104 resumes in Edmonds on Main Street and crosses a BNSF rail line south of Edmonds Station. The highway turns south at an intersection with SR 524 onto Sunset Avenue towards Woodway. The roadway travels southeast along Edmonds Way towards the Snohomish–King county line, intersecting SR 524 Spur and 5th Street at a grade-separated interchange. Edmonds Way travels through a partial cloverleaf interchange with SR 99 before SR 104 intersects its spur route, which travels west towards an at-grade signal with SR 99. The highway continues east along Ballinger Way to a partial cloverleaf interchange with I-5 southeast of Lake Ballinger. The highway travels southeast into Lake Forest Park, where SR 104 ends at SR 522 on the north shore of Lake Washington. SR 104 is considered, by the Washington State Department of Transportation (WSDOT), an auxiliary route of US 101, part of a numbering system established during the 1964 state highway renumbering. Every year, WSDOT conducts a series of surveys on its highways in the state to measure traffic volume. This is expressed in terms of average annual daily traffic (AADT), which is a measure of traffic volume for any average day of the year. In 2011, WSDOT calculated that between 3,800 and 44,000 vehicles per day used the highway, mostly in the Shoreline area. The Edmonds–Kingston ferry carried 3.808 million passengers and 2.025 million vehicles in 2012, according to WSF statistics. The segments of the highway between Discovery Bay and Kingston and SR 99 and I-5 in Edmonds and Shoreline are designated as part of the National Highway System, while the whole route is designated by WSDOT as a
