The superstructure of the original eastern section has been demolished after being replaced by a US$6.5bn self-anchored suspension bridge, which opened in 2013.

The oversight committee of California's transportation department, Caltrans, has now approved proposal to award Kiewit Manson a contract for the construction of the public access observation structures at pier E2 and between piers E23 and E21. Piers E19 and E20 will be removed under the contract.

The new observational areas on the piers at Yerba Buena Island and the Oakland Shoreline will have views of the Port of Oakland and the new bridge. As well as seating and areas for picnics, the larger 185m-long by 8m-wide Oakland shoreline structure will have space for fitness activities, markets and educational exhibits.

The aim is for major marine and structural work to begin in June for completion by the end of 2018, though some other work is expected to extend beyond this year.
