Engineers like Ray Daly are working hard to prepare the Sydney Harbour Bridge for its centenary in 2032 – and some innovative maintenance techniques are involved.

Thousands of commuters pass over the Sydney Harbour Bridge every day, but how many spare a thought for the engineers tasked with maintaining it?

Ninety-plus years on, one of the country’s most photographed structures survives because people show up. Not with gadgets, but with planning windows, containment, careful blasting, and coats counted one by one.

As the bridge’s centenary in 2032 approaches, the lesson stays the same: smart engineering isn’t always doing something new. Sometimes, it’s about doing the right things, the right way, for a very long time.

Revisit the bridge’s construction, 100 years on, in this on-demand webinar from Engineers Australia.
