Sydney Harbour Bridge Railway Deck Upgrade

RKR Engineering & Rhomberg Rail Australia were delighted to support Sydney Trains with the Sydney Harbour Bridge Railway Deck Upgrade project.

Our project scope included the provision of specialist labour and plant to replace and refurbish structural steelwork, replacing the existing timber transoms and railway deck with a continuous concrete slab deck. Delivering these works plays to the unique bridge and structure skills of RKR Engineering. Rhomberg Rail Australia also assisted on this project with both the construction and resurfacing teams supporting.  

Our national icon comprises of ten lanes, two for rail and eight for road traffic. Sydney Trains operates approximately 500 services across the Bridge each weekday and the planned upgrade is expected to extend the life of the railway corridor by 120 years.

 

The complex engineering required for this project included removing the existing railway infrastructure, dismantling the timber deck and installing 266 locally made concrete panels. Installed to replace the ageing 555-metre timber deck on the northern and southern approaches, the concrete composite deck will reduce maintenance by being more robust and using longer lasting materials.

 

NSW Minister for Transport and Roads Andrew Constance acknowledged the work of teams who completed the work during a 10-day shut down. “I would like to thank the more than 420 people who worked through the heavy rain and around the clock to complete the biggest upgrade to rail over the bridge in its history.” he said.

 

Our works on this project are ongoing as we continue to support Sydney Trains with the upgrade and maintenance of our National icon.
