Washington State Ferries
government agency that operates automobile and passenger ferry service in the U.S. state of Washington
Washington State Ferries (WSF) is a public ferry system in the U.S. state of Washington that carries passengers and vehicles. A division of the Washington State Department of Transportation (WSDOT), it operates 8 routes serving 20 terminals within Puget Sound and in the San Juan Islands. The routes are designated as part of the state highway system and also comprise a major public transit network in the Seattle metropolitan area. WSF is the largest ferry system in the United States and carried 20.1 million total riders in 2025, of which 10.7 million were passengers and 9.4 million were driving vehicles. The agency carried an average of 54,900 per weekday in the second quarter of 2026.
The ferry system began operation on June 1, 1951, after the state government acquired routes, vessels, and terminals from the Puget Sound Navigation Company, a private company that had a virtual monopoly on ferries in the region. The company had sold its assets after it was barred from raising fares in the 1940s and was unable to cover rising costs. Under state control, the ferry system was modernized and expanded through the use of custom-built vessels that could carry larger numbers of passengers and vehicles. WSF was originally a division of the Washington State Toll Bridge Authority and was transferred to WSDOT control in 1977.
WSF maintains a fleet of 21 vessels that are able to carry passengers and vehicles.
This brief starts where responsible research should: with the source description of “Washington State Ferries” as government agency that operates automobile and passenger ferry service in the U.S. state of Washington. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as government agency that operates automobile and passenger ferry service in the U.S. state of Washington. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Jul 19, 2026. The linked authority identifier is Q3500373. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2025, 2026, 1951 and 1977.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
