The project is particularly complex from a technical and organisational point of view because it involves maintaining the road traffic, railway and shipping transit from and for the port throughout the entire period that the works are being executed; there are also plans to move numerous subservices and solve serious issues such as a thermoelectric plant, numerous oil extraction wells and a railway line in operation.
The construction of the Gerald Desmond Bridge meets the needs of replacing the existing structure with a more modern one, which meets the earthquake standards and also aims to improve traffic flows. The bridge, on which construction began in 1960 and which, in the meantime, became the symbol of Long Beach, can no longer support the current volumes of traffic which are constantly increasing.
