The bridge is in the U.S. state of California and crosses the San Francisco Bay between Yerba Buena Island and Oakland.

HIC or HAC - hydrogen induced or hydrogen assisted cracking is a real weldability concern that must be addressed in HY-80 steels. Hydrogen embrittlement is a high risk under all conditions for HY-80 and falls into zone 3 for the AWS method. [19] HAC/HIC can occur in either the Fusion Zone or the Heat Affected Zone. [20]
The world’s first hydrogen-powered commercial passenger ferry will start operating on San Francisco Bay as part of plans to phase out diesel-powered vessels and reduce planet-warming carbon ...
Hydrogen embrittlement may occur as a side effect of electroplating processes. Delayed failure is the fracture of a component under stress after an elapsed time, is a characteristic feature of hydrogen embrittlement (2). Hydrogen entry into the material may be effected during plating, pickling, phosphating, melting, casting or welding.
It is the part of San Francisco–Oakland Bay Bridge complex that crosses Yerba Buena Island. The Yerba Buena Tunnel carries ten lanes of Interstate 80 (I-80) on two decks, connecting the two component spans of the Bay Bridge, the western suspension span and the eastern self-anchored suspension span.
