In October 2016, the Transportation Authority, in coordination with Caltrans and the Treasure Island Development Authority, opened the new westbound I-80 on- and off-ramps that connect Yerba Buena Island and Treasure Island to the Bay Bridge.
The project improved traffic safety, geometric design, and traffic operations on and near the ramps.
