The Gerald Desomond Bridge replacement project wil provide a new cable-stayed crossing linking Terminal Island in the Port of Long Beach with the Long Beach Freeway and the centre of Long Beach city in Los Angeles county.
It is believed to be California's first long-span cable-stayed bridge.
The new bridge will have a 305m-long main span and two 152m-long side spans, suspended 61m high over the port canal Back Channel. Access viaducts are 900m and 1,155m long with spans between 57m and 69m.
The main span's 47m-wide deck is formed by longitudinal steel beams and transversal beams placed at 5m intervals; these will support the precast concrete deck sections. Two towers, which are around 155m high, carry a distinct cross section that transforms from an octagon to a diamond.
