To transport the 120,000 daily passengers at Phoenix Sky Harbor International Airport, PHX Sky Train - a free, 24-hour transportation service - has been extended 2.5 miles from Terminal 3 to the Rental Car Center where 5,300 cars are rented daily.

Stage 1 of the project linked parking lots, garages, Light Rail Stations, and Terminal together to increase traveller efficiency and improve the overall experience. Stage 2, included construction of the guideway running surface, expansion of the maintenance facilities, new trains refreshed with improved signage and wayfinding to help guests navigate the train schedules, and connection to the new Rental Car Center terminal and Ground Transportation Center terminal at 24th Street.

Future phases include moving Terminal 2 airlines to Terminal 3, demolishing Terminal 2, and building the West Ground Transportation Center and future station for an additional West terminal.

Sky Train achieved LEED certification.

MCH provided full-scope acoustical consulting and AV infrastructure & systems design.
