The San Francisco County Transportation Authority administers and oversees the delivery of the Proposition K (Prop K) half-cent local transportation sales tax program and New Expenditure Plan, which was passed by 75% of San Francisco voters in November 2003. The Authority was created in 1989 to administer Prop K's predecessor, the Proposition B half-cent transportation sales tax program, which began in 1990 and continued until it was superseded by Prop K.
