This 8 span continuous, 4 lane, 226 m long precast concrete girder bridge crosses Bathurst Harbour and was constructed in 1997 to replace an existing bridge. The 28± m span configurations avoided interference with the existing piers. The bridge girders were constructed using precast prestressed concrete NBDOT Type 1 beams.
The prestressed concrete girder structure was supported on economical pipe piled bents in an aggressive marine environment. A cathodic protection system was developed to extend the life of the steel pipe piles considering the harsh marine environment.
In order to reduce the substructure costs, pile load testing was performed early in the design.
The bridge has a 2 m wide pedestrian sidewalk on the west side with a custom aluminum pedestrian railing and light standards.
