T.Y. Lin International (TYLI) was appointed as part of the design-build contract to provide Civil & Structural (C&S) Engineering services for the Changi International Airport, Terminal 4 project in Singapore. In particular, TYLI was responsible for the C&S design of five vehicular bridges, one single-span bridge crossing an existing underpass, and one pedestrian bridge.

Changi Airport Group is developing Terminal 4 and its associated infrastructure to serve the growing demand for air traffic at Changi International Airport. The new facility is due to commence operations in 2017.

Project Highlights:

  • The airside vehicular bridge consists of two sets of dual carriageways in a single, elevated structure: a 2-lane carriageway for buses carrying passengers from Terminal 4 to remote aircraft and a 2-lane carriageway that links service vehicles to a main boulevard, as well as provision for high-tension cables and information technology services.
  • Three ramp bridges provide vehicular access to the airport terminal for passenger pickup and drop-off.
  • The 2-lane landside overcrossing enables vehicles to access Terminal 4 and other terminals.
  • The single-span bridge forms part of the proposed service road network and was designed to cross over an existing underpass.
  • The overhead pedestrian bridge across Airport Boulevard links pedestrians to Terminal 4 from a bus shelter.
