Phoenix Sky Harbor International Airport in the US has opened Sky Train, the $1.58bn automated inter-terminal train system designed by architecture firm HOK and engineering firm Gannett Fleming.
The 1.92-mile-long PHX Sky Train segment will connect the region’s Metro light-rail station with the airport’s economy parking structure and 88-gate Terminal 4.
HOK has also designed the new 44th Street Metro light-rail station, the station inside Terminal 4 and an outdoor station in the economy parking area.
HOK senior design architect for the project Chris Anderson said that the 44th Street station will be a symbol for Sky Harbor and the city as a whole.
The opening of the PHX Sky Train marks the completion of the first of three planned stages and includes three elevated passenger stations.
The PHX Sky Train will serve as a hub for smart transit or transit-oriented development in the region.
HOK said the PHX Sky Train will establish a new framework for the city’s growth by connecting Phoenix with Sky Harbor.
HOK Los Angeles director of design Ernest Cirangle said that there were two big challenges in designing the project.
"One was that everything had to fit seamlessly within very complicated existing conditions," Cirangle said.
Cirangle added that the second challenge was determining the overall design language.
PHX Sky Train is expected to reduce the airport’s greenhouse gas emissions by approximately 6,000 tonnes per year.
