Amy Street Rail Bridge

NSW
Auburn City Council
2013 - 2016

Auburn City Council appointed Abergeldie to demolish the existing two-lane Amy Street bridge over the railway line near Regents Park railway station and design and construct a new four-lane road bridge. The project also included extensive reconfiguration and widening of the roundabout intersections at both ends of the bridge to accommodate additional traffic lanes and longer slip lanes for vehicles queuing to turn. These upgrades addressed the previous bottleneck caused by the narrow bridge and roundabouts, which had led to significant traffic delays throughout the day.

Scope of Works

The scope of work was designed to meet both standards from Auburn City Council and Rail Corp and included:

  • Demolishing the existing bridge span and central supporting pier.
  • Designing and constructing a new four-lane bridge span.
  • Relocating buried and overhead service lines.
  • Modifying bridge piling, abutments, headstocks, and retaining walls.
  • Fabricating, delivering, and installing bridge girders and precast decking.
  • Completing bridge decking, approach slabs, kerbs, railings, and safety barriers.
  • Installing street lighting, widening and paving the road, and realigning footpaths.
  • Line marking and signage.

Successful collaboration in delivering works during rail possessions

The team worked closely with the rail authority to carefully plan and successfully complete the works within tight time frames set by the design approval process. Demolishing and modifying the central pier and existing bridge abutments, which were rail assets, required approval from the rail authority, adding to the complexity. Much of the bridge construction took place during scheduled rail possession periods, while works adjacent to the live rail corridor followed strict safety protocols. The team navigated these challenges with precise sequencing and scheduling, ensuring timely completion at each stage.

Managing multiple service adjustments added further complexity, requiring close collaboration with third-party service owners and operators. Temporary traffic management was also a significant hurdle, as the extended bridge closure necessitated an intricate detour system. The proximity of the construction site to both live road and rail traffic heightened the need for careful coordination and safety measures throughout the project.
