The new East Span will feature the world's largest Self-Anchored Suspension Bridge, which will also be the first bridge of its kind constructed with a single tower. The innovative design features state-of-the-art seismic safety elements and will provide the East Span with a modern, streamlined appearance and a graceful tower that will be right at home in a region recognized and celebrated for its breathtaking bridges. The Yerba Buena Island Transition Structure (YBITS) will connect the Self-Anchored Suspension (SAS) span to Yerba Buena Island (YBI), and will transition the East Span’s side-by-side road decks to the upper and lower decks of the YBI tunnel and West Span. The Skyway, which comprises much of the new East Span, will drastically change the appearance of the Bay Bridge. Replacing the grey steel that currently cages drivers will be a graceful, elevated roadway supported by piers, providing sweeping views of the Bay. The side-by-side east and westbound decks will each have five lanes along with 10-foot-wide shoulders to help keep traffic flowing. When completed, the Oakland Touchdown (OTD) will connect Interstate 80 in Oakland to the new side-by-side decks of the new East Span. The project involves building two roadway sections and a new electrical substation, in addition to extensive relocation of underground utilities.
