The major application for the Rocla M-Lock® bridge system has been for timber bridge replacements in rural regions; however, over the past few years a niche market has opened in subdivision bridges.
Rocla recently supplied two M-Lock® bridges to the Camden Council area in southwest Sydney.Both bridges provide entrances to subdivisions, one residential and one industrial.
Both bridges were built by civil contractor Cleary Bros of Port Kembla, NSW, and each consists of three spans mounted on Rocla Duraspun® concrete piles.
The residential subdivision bridge at Mt Annan features painted fascia panels cantilevered from the sides, to blend with landscaping and to conceal a water main.
The industrial subdivision bridge at Smeaton Grange bridge is a dual carriageway design with an opening between the two roadways.The grid mesh opening allows light to penetrate under the bridge, providing a non-threatening wildlife corridor for native fauna.
Construction manager for Cleary Bros, Ian Noy, said the bridges were his first experience of the M-Lock® system but that it “went together nicely”.
“The system is fairly self-explanatory,” Ian said, “and we received first-class support from Rocla.”
