The Victoria Bridge is one of three landmark structures crossing the Brisbane River constructed by Baulderstone. The project comprised construction of a 313m long bridge including foundations, piers and abutments and a two lane underpass immediately behind the southern abutment.
The 3 span superstructure consists of pre-cast, post-tensioned hollow concrete box girders. Each girder was made up of 110 precast segments. The 142m main span included a 27m suspended span. The deck between the girders was cast-in-situ as were the cantilevered footways on each side of the bridge. The bridge was founded on 7m octagonal prestressed concrete piles, each up to 40m long. The precast segments which varied in weight between thirty and fifty tons were manufactured in the company’s casting yard. They were cast on a base supported on falsework to the same profile as the bridge, each being match-cast against the preceding unit with a spacer between to correctly position the unit and to ensure that ducting matched.
Erection was carried out by constructing falsework between the shore and the main piers. Precast units were erected two at a time firstly on the shore side and then by cantilevering out across the main span with the out of balance moment being taken by the falsework. Post-tensioning proceeded four units at a time after joints were grouted.
