Turning a precast bridge into a landscape feature

A Rocla M-Lock® bridge system with custom-made fascia panels provided an attractive entrance for a new residential development in western Sydney.

Twin Creeks is a unique rural residential development set around a golf course at Luddenham in the Nepean Valley. The 800-acre (324ha) site, which is being developed by Crownland Developments and the Marsim Group, is a master-planned community with large one-acre lots, an 18-hole golf course and a Peppers resort.

Because the bridge crosses Cosgrove’s Creek at the entrance to the estate, the developers wanted something more than a traditional crossing. Adding arched side panels to an M-Lock® bridge provided an aesthetically pleasing bridge with all the precast advantages of speed and ease of construction.

The 36-metre bridge comprises three 12-metre spans. Total width is more than 13 metres, with a 1.2-metre wide steel grate along the median strip to allow light to reach plants growing beneath. The bridge includes a 2.4-metre wide footpath on one side and a cast in situ barrier on the other.
