Tatham Bridges

Tatham Bridges

The Tatham Bridges are a set of bridges located on the Casino to Woodburn Regional Road (MR145). The route is key to freight, tourism, and agriculture, such as sugar cane and livestock, and is the link between the Casino and eastern localities of the Richmond Valley.  

Deep Creek and Spring Gully (Tatham Twin Bridges) bridges on Casino-Coraki Road over Shannon Brook and Spring Creek, respectively, are Doolan Deck-type bridges (timber girders composite with a concrete deck). Richmond Valley Council engaged Bridge Knowledge to provide detailed design for the replacement of these bridges due to evidence-based concerns over the remaining serviceable life.  The detailed design for two new bridges and associated roadworks has been completed and funded by Council. 

Council has received $18 million of funding through the Australian Government’s Northern Rivers Recovery and Resilience Program 2022-23, jointly administered by the NSW Reconstruction Authority to raise the level of the two bridges at Tatham (between Casino and Coraki).  

This will be achieved by building two new bridges, which will increase the road’s flood resilience, improve access during larger flood events, and provide a better evacuation pathway from Coraki to Casino. The bridges are part of a critical connection between the Summerland Way and Pacific Highway and transport links to Southeast Queensland.  

Construction is expected to commence in mid-2024, with an expected completion timeframe of mid-2025.
