Forward Notification - North Johnstone Bridge Replacement

Brief

This notice is issued for informational purposes only. No Scope of Works or additional details are available at this time. A future tender will seek to engage a Principal Contractor to undertake the construction of the North Johnstone River Bridge Replacement project, which involves the construction of a new single track railway bridge over the North Johnstone River, approximately 4 km north of Innisfail on the North Coast Line (NCL) in Far North Queensland. The existing bridge, located at approximately chainage 1597.870 km, has been in service for approximately 100 years and currently supports both passenger and freight rail operations. Due to age related deterioration, increasing maintenance demands and ongoing structural performance concerns, Queensland Rail has initiated the replacement of the existing structure to ensure the continued safe and reliable operation of the rail network. The project has been developed as an offline bridge replacement to minimise disruption to rail operations during construction and to improve constructability and safety outcomes. The proposed works include significant enabling and temporary works to facilitate construction and demolition adjacent to a live operational railway and within a constrained river environment, construction of a new rail alignment offset approximately 17 m downstream of the existing bridge, construction of a new six-span prestressed concrete rail bridge, associated earthworks, drainage, rail infrastructure, rail maintenance access roads (RMAR), utility relocations, temporary works, demolition of the existing bridge structure, and reinstatement works Please refer to the attached Forward Notification for further details.
