San Francisco - Oakland Bay Bridge East Span Design: Page 1 | Page 2 | Page 3 Donald MacDonald Architects provided design services for the new San Francisco-Oakland Bay Bridge (east span). Working with the acclaimed New York bridge engineering firm of Weidlinger Associates, the team designed and conceptualized various modifications on a self-anchoring suspension bridge concept, originally selected by an Engineering Design Advisory Panel. The MacDonald/Weidlinger team also worked with the joint venture of T.Y. Lin Associates International /Moffat and Nichol to create a signature bridge for the San Francisco Bay. The MacDonald/Weidlinger team won a limited design competition against the team of H2L2 Architects and T.Y. Lin's Seattle office. The H2L2 / T.Y. Lin team had designed a cable-stay bridge for the East Bay crossing. An Engineering Design Advisory Panel was selected by the regional Metropolitan Transportation Commission to review and judge the competition through different stages of development.

These concepts were tested for structural integrity and aesthetics. Models, architectural renderings done by hand and computers, and structural analysis all played a part in the final winning design.

Many other features, such as renderings, material samples, montages and lighting effects, are also studied in the overall composition to create signature structures.
