Maria Ayerdi-Kaplan, Executive Director
Ms. Ayerdi-Kaplan leads and manages the $4.5 billion Transbay Transit Center Project— “the Grand Central Station” of the West. The Transbay Project consists of a new multi-modal Transit Center on the site of the Transbay Terminal in San Francisco, the extension of rail service from 4th and King Streets to the new Terminal, and a redevelopment area surrounding the new Transit Center. Featuring intercity, regional, and local buses along with commuter and future High-Speed Rail, the Project will ultimately connect 11 different public transit systems. The Project will also create a 40-acre pedestrian friendly community of 2,600 new housing units, one-third of which will be affordable. By providing the public with safe, convenient, and inexpensive public transit options, and by creating a livable community near transit, employment, shopping, and other urban amenities, the Transbay Project is a national model for the integration of land use and transportation planning. The Project is more than a vision; it is the first High-Speed Rail project to break ground in the United States. Read more
