A floor-by-floor diagram of the transit center.
The replacement for the old Transbay Terminal is designed to function as both a bus station and a civic destination. Bus service should begin with roughly 15,000 riders a day, while the center’s retail spaces and rooftop park are intended to attract visitors from the high-rise neighborhood sprouting around it. A contemporary twist? The name will be Salesforce Transit Center – after the local software firm, which signed a 25-year sponsorship agreement valued at $110 million.
Rooftop park: The 5.4-acre City Park was conceived by Berkeley’s PWP Landscape Architecture as an interlocked set of public spaces – there is a picnic meadow, a playground and a jogging path amid hillocks and botanical displays including 60 species of trees. The west end will have an amphitheater and a restaurant. A snaking line of water jets will be triggered by the movement of buses below .
Bus deck: The third level of the structure will hold 37 bus bays around an elongated central island, where riders will wait, board and depart. The main tenant will be AC Transit, but some bays will be used by other buses crossing the bay, including Muni’s Treasure Island service. Unlike the gloomy 1939 terminal, this waiting area will be naturally lit and ventilated, thanks to the see-through panels that surround it. Salesforce Tower Central Lawn NATOMAST.

The alleys: The transit center is intended to have ground-floor activity on all sides, including the long-quiet alleyways of Minna and Natoma streets. This view of the center’s west flank shows shops along Natoma Street beneath the metal awning, with paving and landscaping keyed to a pedestrian scene. The structure at the end holds elevators to the rooftop park.
