The new Yerba Buena/Moscone Station on the Central Subway line is a celebration of transportation as civic art. After the Loma Prieta earthquake damaged the freeway in 1989, the central subway was part of the planned improvements to public transit in San Francisco. These improvements included three new stations: Yerba Buena/Moscone, Chinatown – Rose Pak, and the Union Square/Market Street Station. The MWA team collaborated on this project from concept designs in 2010 through completion in 2022.
This new subway station is located in a vibrant urban core, creating a more accessible, walkable, and sustainable downtown. Our team designed and coordinated our work with the other station and tunnel designers, the Art Commission, and the client, SFMTA.The primary design challenge was to provide natural light in an underground space. Designers implemented a glass ceiling at Yerba Buena/Moscone Station, acting as a massive skylight for all three stories. The glass ceiling defines the exterior and provides natural light from the ticketing level down to the transportation level.
Designed to support the resilience of the community during times of need, a generator cap will continue to power the station and lightrail during a power outage. Durable materials such as stainless steel, concrete, and tile will withstand the impact of thousands of passengers, keeping this public asset looking fresh and easily maintainable with an estimated lifespan of over one hundred years.
