I-80 East Side Ramps Project

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 eastern span of the Bay Bridge. The project improved traffic safety, geometric design, and traffic operations on and near the ramps. 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 support the Treasure Island Transportation Program. This project has received several achievement awards: 2018 Best Project, Highways/Bridges category, Engineering News-Record California 2017 Interchange Project of the Year, California Transportation Foundation 2017 Transportation Project of the Year (over $50M), Construction Management Association of America, Northern California Chapter 2017 Merit Award, American Council of Engineering Companies 2017 Roadway & Highway Project of the Year, American Society of Civil Engineers (San Francisco Section) 2017 Outstanding Construction Project of the Year, American Society of Civil Engineers (Region 9)
