White Bridge Restoration Brownhill Creek
The “White Bridge”, located on Brown Hill Creek Road within the Brown Hill Creek Recreation Reserve was damaged during a storm event in September 2016 and required significant strengthening and restoration work to return it to serviceability. “The White Bridge” has significant heritage value within the Brown Hill Creek Recreation Reserve and is one of the first bridges constructed in the Adelaide Metropolitan area during the 1800’s.
Residents south of the bridge have no other entry or exit option than crossing the bridge. Neo proposed an alternative construction methodology to eliminate access issues for the residents and provide an overall cost saving on the bridge restoration component.
Aside from the structural restoration, Neo had reinstated the rock pitching to the damaged wingwalls and repointed all of the architectural rock on the bridge abutments. The underside of the bridge was treated and strengthened to increase the bridge loading capacity.
