Environmental management is a key priority during construction of the Forrestfield-Airport Link. Building the new line underground will reduce the impact to the natural environment, local residents and businesses.
The Forrestfield-Airport Link’s two tunnels will be constructed with 54,000 concrete segments. A Forrestfield warehouse has been transformed into a facility to batch the concrete and create segments to line the two tunnels.
Tunnel boring machines (TBMs) are large machines that excavate below the ground surface, while simultaneously installing concrete lining units to build a tunnel.
Emergency egress shafts provide safe exit points in the event of an emergency, and access to the Forrestfield Line's twin-bored tunnels for maintenance,
Located immediately south of the control tower adjacent to Terminal 1 and 2, Airport Central Station will provide passengers with a direct 18-minute train journey to the CBD.
