Onsite update

Construction of the Old Māngere Bridge Replacement is well underway. With the first bridge span completed, the team have moved onto the second span and so far we have placed two of the seven concrete beams.

We are now removing the temporary works around our largest pier (pier two) which includes the scaffolding, formworks and the sheet piles which created the cofferdam. Due to the size and scale of this pier, this work will be completed around the end of June.

Another team is working on the second large pier (pier 3), which supports the other side of the central steel deck and arch. The pile cap and plinth (base) have already been completed and the team is now forming the four 14m tall ‘v’ shaped columns which the bridge deck will sit on.

We also have two more small piers (pier four and seven) located on the southern side underway.

Deconstruction of the old bridge resumes

Work on the western side of the Old Māngere Bridge has focused on building a second temporary work platform which is needed to enable us to restart deconstruction of the old bridge.

The deconstruction work is being undertaken by a kiwi owned family business which specialises in concrete cutting and deconstruction and at time of going to print, we’ve removed eighth spans from the old bridge with nine spans left to go.

By mid-2021, this second temporary work platform will extend much closer to the public boat ramp at the end of Coronation Road. While access to the boat ramp will be maintained, we ask users to please take extra care when navigating around the area.

Don’t forget to check out the notice board with some helpful user guidelines before you head into the water so everyone can stay safe whilst enjoying the Manukau Harbour.

Deck and arch section arrives on site

Arrival of the arch and centre deck pieces on site

It was an exciting day on site when we took delivery of one of the first end sections of the steel arch. In total there are 18 steel pieces which are being made in Napier and the team will weld these together to create three larger pieces which will then be craned onto site to create the central span and arch of the new bridge.
