The Lambert Airport Experience Project was a comprehensive masterplan to modify and upgrade the existing historic St Louis International Airport and restore a sense of functional, aesthetic and experiential clarity. The original terminal, a series of cast-in-place concrete vaults designed by Minoru Yamasaki in 1953, was instrumental in defining the vocabulary of the modern airport. In 2000 the airport served 30 million passengers annually, by 2005 this number had reduced to 15 million. Aside from attracting new airlines, the aim of the Experience Project had several main objectives: to redefine the airport as a public space and a gateway to the region; to clarify and simplify wayfinding; to technically and functionally upgrade the facility; and to integrate post-9/11 security standards. Through a series of large-scale reductive interventions - most significantly the introduction of a large opening in the ticket hall floor and lowering of the arrivals level roadway - the space is visually expanded to introduce natural light, orient passengers and allow for intuitive wayfinding. Departing and arriving passengers are collected and disbursed from a single central point. A glazed canopy over the arrival and departure-level roadways reflects the language of the original domes and extends the public space beyond the terminal. As project designer my involvement extended from conceptual initiation through final delivery and included design and coordination, passenger/traffic flow analyses, preparation of document sets, presentations, marketing materials and
