A 35-metre steel pylon will be erected overnight at the site of the new Beachcroft Avenue foot bridge over the Southwestern Motorway (SH20) at Onehunga.
The pylon will support a new cable-stayed foot bridge that is expected to become a landmark on Auckland’s planned Western Ring Route.
It will be lifted into place by crane under an overnight closure of the northbound lanes of the motorway.
The new Beachcroft footbridge will replace an existing bridge that is too short to fit across all lanes of the widened motorway below. It will be a 3.5-metre wide shared cycle and pedestrian bridge connecting Hillsborough and Onehunga.
Work on the new Mangere bridge continues
The bridge’s bright blue trusses will be installed, also under night closures of the motorway, later in February.
It is expected to be completed in early April, after which the existing bridge will be demolished. Both the pylon and the deck trusses of the bridge have been manufactured by New Plymouth based company Taranaki Engineering.
The footbridge is being built as part of the Manukau Harbour Crossing project, which is doubling the motorway’s capacity from Queenstown Road in Onehunga to Walmsley Road in Mangere.
The project includes the new, four-lane bridge across the Manukau Harbour for southbound traffic.

There’s a lot of past mistakes to fix, but at least these days NZTA are a lot more proactive about pedestrians and cyclists around their projects…
