Like many large, urban airports, the Los Angeles International Airport faces increasing capacity demands coupled with a site severely constrained by existing development. The Southern Runway Complex is built over a 1950's era tunnel that allows Sepulveda Boulevard, California State Route 1, to pass under the airfield. The tunnel was strengthened in the 1970's and 80's to accommodate larger and heavier aircraft, but the existing structure was not long enough to accommodate the dual taxiway system on the north side of the south runways. As a result, there is currently substandard separation between Taxiway "C" and Taxiway "B" at the tunnel. In addition, Taxiway C is intersected by the airport's busiest vehicle service road on both sides of the tunnel, restricting its use to small commuter and towed aircraft, and creating a bottleneck to efficient operations. At its core, this paper discusses a relatively simple realignment of the taxiway and service road to improve airport operations. The engineering challenge lies in imposing a simple solution on a complicated, congested site, and designing the elements of the total solution based on the impacts to existing facilities. These elements include construction of a taxiway bridge over a busy state highway, several facility modifications, utility relocations, and an extensive upgrade of the 45 year old tunnel ventilation and lighting systems, all with minimum interruptions to both aircraft and vehicular traffic, and in coordination with federal, state and local authorities. This project presents a prime example of the difficulties involved in designing major infrastructure improvements at a congested, existing site. Through careful investigation, analysis, and design, this project will meet the primary goal: to increase efficiency while minimizing disruptions to the public and to the existing operations.
