About

The project features the construction of a new 250 m long rail bridge over the St Lawrence Creek, demolition of the existing steel truss structure constructed in the 1920’s and a 1.2 km deviation of the North Coast Rail Line.

The biggest challenge on the project is the location, and in particular the extreme tidal range and high flows of St Lawrence Creek. To overcome this, a temporary falsework bridge will be constructed allowing the team to complete all works on the main structure with minimal impact from the fluctuating tides.

Works will be further challenged by the proximity of the new bridge to the fully operational existing rail bridge. Coordination with Queensland Rail, will ensure no delays to the operating trains and without compromising the safety of workers, the public or Queensland Rail’s network.

Careful environmental management, during both construction of the new and demolition of the existing structures, will ensure local fish and turtle populations are not impacted by potential hazards such as ASS, water contamination and dust.

“Operationally critical short night closures were completed on time and without incident with teams from both SWC earthworks and Queensland Rail track workers completing their activities at the same time. SWC embraced the number one Queensland Rail policy of zero harm and were relentless in their endeavours to eliminate any injuries through a well developed safety culture, subcontractor training and support. Please accept my thanks for a job well done and for Seymour Whyte’s constant professionalism and thoroughness that enabled the project to be completed safely and ahead of time with an exceptional final product.”
