"Toll collector Marilyn Alvardo receives the last toll from Jim Eddie who is driving a vintage 1937 Packard, at her tollbooth at the Golden Gate Bridge toll plaza in San Francisco, California March 27, 2013. The Golden Gate Bridge will convert from manned tollbooths to a full electronic tolling system starting March 27. With the automated system in place, motorists will have the option of using the existing FasTrak electronic toll collection system or the newly implemented pay-by-plate option."
