This was VEC’s second project utilising a barge to build the entire foundation from the water. The bridge was built adjacent to the existing bridge on a curved alignment to facilitate tie-in to the existing road alignment. VEC completed the project on time and to client specifications, providing a lasting landmark for the Ulverstone community.
The bridge is a 154m long structure comprising four 32m simply supported central spans of 1510mm deep pre-tensioned T-Roff girders and two 13m long simply supported approach spans of 475mm deep pre-tensioned gap-spaced planks.
The precast girders and planks have a compositely acting reinforced concrete deck slam with a 50mm thick asphalt surfacing.
All girders and planks were precast at VEC’s Ulverstone Precast Yard.
The superstructure is articulated with a steel finger plate expansion joint at Pier 3, reinforced concrete link slabs at all other piers, and pinned connections to each pier and abutment.
This articulation ensures that each pier/pile support acts as a braced column in terms of its effective length.
