The structure, described as an elevated passenger corridor, will span a taxiway and connect the airport’s North Satellite Concourse with Terminal 1. It will accommodate retail facilities, moving walkways, lifts and escalators.

The Airport Authority is currently inviting expressions of interest for the design and construct contract and plans to issue invitations to tender in the third quarter of this year.

Construction will have to be carried out with minimum disruption to Hong Kong International Airport's operations and is to be completed within a period of 24 months.
