The original Berths 4 and 5 on Rottnest Island were built in 1970 and had reached the end of their serviceable life. Subsequently, they were replaced with new structures that will provide 50 more years of service as the main gateway of Rottnest Island.
The new concrete deck area is 5m longer and almost 5m wider to match the end of Berth 3. The additional length allows for safer clearances for ferry berthing and the extra width will ease congestion in peak times on the jetty.
The project included the demolition of the existing concrete superstructure and supporting steel piles of the existing Main Jetty Berths 4 and 5 and the design and construction of the replacement concrete superstructure with supporting steel piles. The works also included the design and construction of a wave screen along Berth 5 with a return around the end of the jetty.
