In 1999, the Los Angeles World Airports awarded Swinerton Management & Consulting, Inc. (SMCI) a contract to manage the construction of an aircraft bridge spanning Sepulveda Boulevard.
The project was necessary in order to realign an airfield taxiway at Los Angeles International Airport. The $40-million project included joining the new bridge with the north side of the existing Sepulveda Tunnel, extending the tunnel 165 feet to accommodate jumbo jets, and several safety and aesthetic improvements.
As a result of the work, several buildings, including a fire station and a Delta Airlines maintenance building, were modified. In addition to the bridge, the interior lighting system in the 46-year-old tunnel was replaced, the ventilation system was updated to meet current fire safety code, and electrical service and wiring were replaced.
