HNTB was the principal designer for the Bay Area Rapid Transit’s 8-mile San Francisco Airport Extension Line, Track and Systems. This project was an FTA-sponsored turnkey demonstration design-build project and BART’s first design-build project. The San Bruno Station and South San Francisco Station are part of the extension. HNTB’s scope included architectural and structural finishes, a parking structure, on-site civil design and off-site roadway improvements. The project added to the quality of life in the Bay Area and set a new standard for how transit is delivered.
