In 1885-86 the Department of Public Works removed the wall on the upstream (i.e. western) side of the bridge to widen it, and put up the present railing at the same time. In 1901-02 the bridge was strengthened internally for the Castle Hill Tramway. In 1912 the parapet on the western side was removed, providing a cantilevered pedestrian way. In 1934-35 this new section was removed, the Department of Main Roads widening the bridge in order to handle increased traffic. This modification saw the replacement of the cantilevered walk-way with an open concrete type and the straightening of the curved western face.
