Rozella Interchange

Rozelle Interchange

The McElligotts team had the pleasure of providing the protective coating for four additional bridge girders and the outriggers that will form part of the pedestrian land bridge that is currently being constructed for the Rozelle Interchange.

The Rozelle Interchange will consist of an underground motorway interchange between Sydney’s M4 and M5 and is a part of the larger WestConnex project. Overall, WestConnex is Australia’s biggest road project and is being overseen by John Holland and CPB Contractors. Once completed, these tunnels will provide a vital missing link between Sydney’s inner-west suburbs.

While the majority of the Rozelle Interchange project is taking place underground, a new 10-hectare public park space is also being built on top – which includes the construction of a new mixed pedestrian and cyclist land bridge.

The steel girders for this bridge have been fabricated by McElligotts long-term partner Haywards in Tasmania. The protective coating was undertaken by our Tasmania team, applied using airless spray in a workshop using products from Dulux Protective Coatings. The first coat was Zincanode 402, designed to protect steel for harsh corrosive environments, followed by Duremax GPE to the structure’s irregular areas such as its welds and edges. Next came a coating of Duremax GPE MIO to provide enhanced barrier protection to the girder’s surface. Finally, a topcoat of Weathermax HBR MIO was applied to provide lasting protection for all the parts.

McElligotts would like to express its gratitude to everyone on the team who worked on this special project as well as all our partners involved. The first two girders were delivered in November, while the other two will be ready in the new year.
