The Bay Area Rapid Transit System (BART) is a heavy rail public transit system that serves an average of over 400,000 passengers per day in the San Francisco Bay Area.

BART has its own copyrighted map that developers aren't allowed to use in apps, so I made an open source version that anyone can use and update.

With no art direction from anyone, I made this map in about 40 hours over two weeks. I went through many iterations to draw and style the base map, determine the colors and thicknesses of the transit lines, create the silhouettes of the airplanes for SFO and OAK airports, choose a font, and create unique markers to represent end-of-line, regular, and timed transfer stations.
