Salesforce Transit Center is a ground-up, Type I concrete and steel transportation and recreation project. This CMGC project totals throughout one structure with four levels above grade and two levels below grade. Coined the “Grand Central Station of the West” the Salesforce Transit Center replaces the former Transbay Terminal at First and Mission Streets with a modern regional transit hub connecting eight Bay area counties and the state of California through 11 transit systems: AC Transit, BART, Caltrain, Golden Gate Transit, Greyhound, Muni, SamTrans, WestCAT Lynx, Amtrak, Paratransit and the future High Speed Rail Transit System. Bus access to the transit center is provided via a cable stay bridge which connects the Bay Bridge to the Transit Center’s elevated bus deck level.

Built by the Webcor-Obayashi Joint Venture and operated by the Transbay Joint Powers Authority, the center is expected to accommodate 100,000 passengers each weekday, and up to 45 million people per year. In addition to providing access to a variety of transit systems, the project, which stretches nearly four blocks, includes a 5.4-acre public rooftop park featuring an amphitheater, restaurants/retail, playground and fountains as well as a wide variety of natural beauty via signature landscaping design. The park is accessible to the public by stairs, escalators, and elevators to a gondola on Mission Street and sky bridges from adjacent high-rise towers.

Signature architectural and art elements adorn the building’s exterior, which is wrapped with a metal awning that features the Penrose Pattern – a continuous non-repeating pattern derived from a mathematical formula. The awning is both a veil and an enclosure creating a light cloud-like structure.
