WSP Opus’ DNA is embedded in the foundations of the iconic Auckland Harbour Bridge.

Since opening in 1959, it has required continual maintenance and refurbishment and we’ve played an ongoing role in providing engineering expertise.

This has reduced environmental impact, prolonged the life of the infrastructure and provides better driving experience for users.

Here we take a look at some of the key moments in this crucial piece of infrastructure that transformed the Waitematā harbour.
