Murphys Creek Road, Rocky Creek Bridge, replace bridge
Rocky Creek Bridge was replaced to improve safety, traffic flow, flood immunity and efficiency.
The old Rocky Creek Bridge was originally built in 1928.
The new 2 lane concrete bridge better supports local traffic by improving safety, flood immunity and traffic flow on Murphys Creek Road.
The project included realigning Murphys Creek Road to connect the new bridge to the existing road network. The old bridge was demolished after the new bridge was opened to traffic.
More than 100 native ground cover plants, shrubs and trees are being established on the banks of Rocky Creek including Lomandra, wattle, bottlebrush, blue gum, Moreton Bay ash and river she-oak to replace the vegetation removed for construction.

Project update
During pre-construction, historic sandstone kerbing and channelling (stone pitching) was found next to the old bridge.
The sandstone kerbing and channelling was part of the original Rocky Creek Bridge constructed by the department (the Main Roads Board at the time) in 1928. It was arranged to help minimise erosion and direct water from Murphys Creek Road into Rocky Creek.
To conserve the historic sandstone in the local community, it has been relocated to the Postmans Ridge Pioneer Memorial Hall and arranged to reflect the original shape of the kerbing and channelling.
