Transit Maps Update: 3-23-2008. As promised, AC Transit has now made its official debut on the transit stop maps with the popular 51 Broadway, along with its late night companion, the 851. Also included is the 54 line, which runs along 35th Avenue in Oakland. As with the other maps, documentation of transfer points is largely complete but still a work in progress. An updated list of all currently available maps can be found on the Bay Area Transit Maps page. Looking ahead to future updates: maps for the remaining Muni Metro lines are well underway, along with a number of crosstown bus routes. Another planned feature for BART and Muni subway stations is an explicit marking of all station entrances, exits, and elevators, so that riders may tailor even more closely their transfers between trains and buses. The map markers for station entrances and exits will likely be accompanied by information on available escalators and stairs.
