Gerald Desmond Bridge Project
Joint Venture Members
Salini Impregilo S.p.A.
The Gerald Desmond Bridge Replacement Project was awarded by the Port of Long Beach (CA) to a joint venture of Shimmick Construction, FCC Construccion, and Impregilo S.p.A. in June 2012. S. A. Healy is supporting the Impregilo role in the project. This $649.5 million design-build project is scheduled for completion in mid-2016.
The purpose of the project is to replace the aging bridge with a modern structure that conforms to all updated seismic codes while providing for a 100-year design life. In addition, the new bridge will provide for a minimum 200-ft clearance above the Port channel to accommodate the largest cargo ships, while increasing the vehicular capacity of the I-710 freeway.
The Cable Stayed Bridge
The centerpiece of the project is the cable stayed bridge that will stretch 1,000 feet between the two 500-foot tall pylons, with 500-foot long high approaches at each end. The pylon towers will be unique octagonal single tower structures that transform to a diamond shape at the top.
The Approaches and Interchanges
The approaches to the new signature are designed as a single unit with the main span. The approach bridges are comprised of two independent concrete box girders with cantilever decks. Most of the approaches are constructed using the Moveable Scaffold System (MSS) method. The project also includes new interchanges between the I-710 freeway and Ocean Boulevard, Pico Avenue, and SR-47. A bike path will also be provided across the new bridge.
