The widening of busy Castlereagh Road in Penrith from four lanes to six required the Jane Street rail bridge be replaced with a 35m single precast span.
This ambitious design was made even more challenging by the site constraints, which necessitated components be precast off site and assembled adjacent to the existing bridge. Once complete, the 2,500t structure was to be transported and lifted into place during a six-day rail shutdown.
Evolution was engaged to supply the highly complex, custom precast components to extremely tight tolerances. These included two 180t post tensioned beams—the largest beams ever manufactured off site and delivered in Australia, at the time.
This was also the first complete bridge to have been constructed in this way in Australia. Evolution’s unique capability ensured all items were complete, delivered and assembled to meet the specified tolerances and time frames.
Budget: $2.1m
