Elevated circulation roadways and freeway ramp improvements associated with construction of new a international terminal were included in the San Francisco International Airport master plan. These improvements were intended to improve access to the Airport and reduce congestion at terminal curbside loading areas. In 1994, Leigh Fisher Associates was retained to prepare traffic forecasts, operational analyses, and schematic roadway designs for:

• Modifications to existing inbound and outbound freeway ramps
• Elevated circulation roads serving a new International Terminal and rental car garage/ground transportation center (RCG/GTC)

The conceptual plans analyzed and refined during the study were prepared using base plan concepts developed as part of the master plan and subsequently refined by Airport staff. Leigh Fisher Associates also developed several alternatives to the base plan roadways.

In early 1995, Leigh Fisher Associates updated the traffic estimates, analyses, and roadway designs to reflect changes to the Airport development program. These changes resulted from a "massing study" that significantly altered the proposed configuration of the elevated circulation roadways serving the International Terminal and RCG/GTC.

In late 1995, Leigh Fisher Associates again updated the traffic analyses and roadway designs to reflect changes in key planning assumptions, namely, (1) rental car facilities would be moved to a remote structure and (2) certain commercial vehicles would pick up and drop off passengers on Level 1 of the existing parking garage. Consequently, with relocation of the rental car and commercial vehicle functions to alternative sites, the RCG/GTC was to be designed to accommodate public parking.

Design documents were prepared on the basis of these traffic studies and schematic plans and construction of the improvements is expected to be completed in 2000.
