Vancouver International Airport

Vancouver, British Columbia

Architectura with Bush Bohlman Engineers

Construction: Suspended Walkways

The skywalks are an important feature of the airport, from the point of view of design as well as security. They are used to separate the various types of passengers in respect to destination (Canada, U.S., International) and level of security.

In contrast to the tunnel that visitors first experience upon arriving at the existing terminal, the unique glass-enclosed suspended walkways or "sky bridges" of the new terminal afford panoramic views of Vancouver. These moving walkways are framed with transverse "fish belly" girders (so called because their webs are deeper at mid-span than at the ends) supported by rods hanging from the roof girders. Additional horizontal sway rods ensure lateral stability at the walkway level.
