Under the auspices of RMS in NSW, these four bridges are located through the state’s central west and New England areas. This project was carried out in 2015. At that point the bridges were each about 30 years old. They are each of similar construction, with concrete pillars and decks supported by steel girder superstructure.
The intention of the works was to preserve the ageing exposed concrete decks, given the challenge of accessing them for regular maintenance, and the loaded traffic that uses them.
A painted coating was deemed inadequate due to the likely traffic wear.
One specific challenge was the need to minimize downtime, as the bridges are typically the sole vehicle route for the given remote area.
