System Expansion


BART has developed a System Expansion Policy that states goals and strategies for expanding the system including criteria for evaluating expansion opportunities. 

The Planning Department at BART assesses strategic opportunities for system expansion by conducting corridor studies for future BART services, assessing alternative methods for expanding transit services in the region, completing assessments of environmental impacts of proposed projects, and analyzing opportunities for new stations on the existing system (infill stations).
