The Mangere footbridge provides a 250m long replacement footbridge across Auckland's Manukau Harbour and incorporates a main arch span of 60m. It replaces a 100 year old road bridge which has been closed to traffic since the 1970's and is now used only for pedestrians.
Designed in collaboration with an architect, urban designer and two local artists, the solution provides a delicate balance of attributes to meet the varied stakeholder expectations.
The main span consists of a single steel tied arch which supports steel box girder deck. The arch leans outwards at a 22 degree angle on the outside of a curved deck and is supported on post tensioned concrete "V piers".
Detailed design was completed in 2016 with construction to commence in 2017.
