Project History

The SFMTA originally developed the Connected Corridor Project as part of the city’s 2016 Smart City Challenge proposal to the USDOT. Though this grant was ultimately awarded to Columbus, Ohio, San Francisco was one of seven finalists for the award and was able to pursue other opportunities to advance elements of the Smart City Challenge. From these efforts, the city received an $11 million grant the ATCMTD program, to pursue the Connected Corridor Project and other elements of the Smart City Challenge proposal.
