Nature of work

ARTC sought to undertake major maintenance on multiple underbridges located at Parkes (x 2), Tomingley West (x 1), Dunedoo (x 2), Elong Elong (x 1) and Mickibri (x 1). The bridges were upgraded in preparation for the new Inland Rail Network The work consisted of removing the old timber structures, preparing the site and installing reinforced concrete box culverts, wing walls and associated site works.

The projects objective was to remove the long term track speed restrictions and ultimately increase the tracks long term reliability and lifespan.


Project outcomes

All construction works were completed to design drawings, on time and compliant with the ARTC Code of Practise. Key stakeholders and clients inspected each bridge providing great feedback with no unsettled issues post completion.

The program was tight given the 6 month turnaround between contract award and completion for all 7 bridges. RRA completed the job 4 weeks ahead of the deadline. Environmental challenges were prevalent for this project and involved community liaising, dewatering of the local ecosystems, dust control and spoil management.


Our Role

Rhomberg Rail Australia (RRA) demolished the existing timber structures, excavated the formations, installed new structural formation material, new concrete culverts, track ballast, steel sleepers and all new handrails and walkway. New flood damage mitigation structures were installed such as Concrete apron slabs and reno mattress scour protection.

A short program and continual bad weather proved the most difficult items with RRA mitigating any risk via the delivery model.
