The Southgate Road Relocation will relocate Southgate Road, the critical local connection between the I-80 westbound and eastbound on- and off-ramps, and reconstruct and reopen the I-80 eastbound off-ramp to Yerba Buena Island.
This project is part of an effort to replace and retrofit key roads and on- and off-ramps that connect the I-80 (the highway on the Bay Bridge) and Yerba Buena Island. The Transportation Authority is working jointly with the Treasure Island Development Authority and the Office of Economic and Workforce Development on this effort. These upgrades will support the Treasure Island Transportation Program.
