SAN FRANCISCO (KCBS)— San Francisco Mayor Ed Lee announced $48 million in new voter-approved funding for the city’s transit system on Monday. The money will go toward improvements for the San Francisco Municipal Transportation Agency and the hiring of 244 people— including drivers and maintenance workers.

As the F-Market historic streetcar passed behind him at Castro and Market, Mayor Lee made the announcement of a cash infusion thanks to Propositions A and B, which passed last November and dedicate additional revenue to Muni.

“That’s a great thing for the eighth-largest transportation center in the country,” said Lee.

The new money and hire of 171 bus and train operators and supervisors, along with 73 maintenance workers, will help expand the system and make it run cleaner and on time.

Board of Supervisors president London Breed was one of three supervisors joining the mayor, to unveil what they tout as the most significant improvement to Muni service in decades.

“We have work to do, folks, but I’ve got to tell you, this is a huge step in the right direction,” said Breed.

The mayor said riders should see improvements almost immediately, with the purchase of new hybrid buses and Muni Metro trains, and more enhancements of bicycle and pedestrian safety.
