The project includes the demolition and complete removal of the historical 250 metre long Old Mangere Bridge in Auckland that was originally opened in 1915.
McConnell Dowell will then construct a new shared walking and cycling bridge between the ends of the existing causeway.
The new 300 metre bridge will feature a central 60 metre span in structural steel together with nine approach spans using reinforced concrete.
It will provide up to 6.5 metre clearance for vessels to pass underneath. It will also reinstate a walking and cycling route between the two communities on either side of the bridge.
The replacement bridge will provide a key recreational space for people to sit and enjoy views of the harbour or for those that enjoy fishing.
McConnell Dowell Managing Director for New Zealand and Pacific, Fraser Wyllie said he is looking forward to working closely with the New Zealand Transport Agency to deliver the the communities of Mangere Bridge and Onehunga an iconic bridge.
“McConnell Dowell has a strong track record of delivering iconic and multi-award-winning bridges such as the Waitaki River Bridges, Lower Hatea River Crossing, SH1 Russley Road’s Memorial Road Bridge, and Kawarau Falls Bridge.”
