Westgate Footbridge, Auckland, New Zealand

The Westgate Footbridge provides a new pedestrian and cyclist connection across four carriageways of SH16 near the Westgate shopping Centre in Auckland, NZ. The bridge is 3m wide and 220m long and consists of two separate structures. A curved steel truss under the deck provides a 120m long ramp which allows disabled access gradients to rise 8m over the motorway. A straight 100m long through truss crosses the motorway with 6 spans and minimal structural depth.

The paper presents the background to the project, the solution adopted and the key issues associated with the design and construction of the project.
