Macintosh Island Bridge

Gold Coast, Queensland

This 110 metre cable-stayed pedestrian bridge features diamond-type steel stay cable towers and post-tensioned concrete deck beams. Located on the Gold Coast, it crosses the Nerang River linking the island to the surf beaches and plays a key role during the annual Gold Coast Indy 300 motor race.

The project was built within a very tight five-month program, in advance of the 2007 Indy 300 race. The design incorporated extensive precasting and off-site fabrication; procurement of all of these components had to start long before design completion.

In addition to the time constraint, risk mitigation was a key issue, the solution being to erect the deck on temporary supports to carry a full pedestrian live load, allowing the bridge to be opened early if necessary, without the towers or cables should these be delayed by weather or other constraints.
