Toward the end of the 1940s, the Black Ball Line wanted to increase its fares, to compensate for increased wage demands from the ferry workers' unions, but the state refused to allow this, and so the Black Ball Line shut down. In 1951, the state bought nearly all of Black Ball's ferry assets for $5 million (Black Ball retained five vessels of its fleet). The state intended to run ferry service only until cross-sound bridges could be built, but these were never approved, and the Washington State Department of Transportation runs the system to this day.
