Pacific Highway – Woolgoolga to Ballina – Harwood Bridge

The Harwood Bridge upgrade over the Clarence river is a project within a project and forms part of the larger AUD $4.36 billion Woolgoolga to Ballina Pacific Highway upgrade along the Eastern corridor connecting Sydney and Brisbane.

Jointly funded by the state and federal governments, the Woolgoolga to Ballina Pacific Highway upgrade is one of the largest road infrastructure projects in NSW and once complete the upgrade will improve road safety, reduce travel times and increase transport efficiency along this section of the highway.

On the 29 April 2016  Acciona Ferrovial Joint Venture was announced as the preferred tenderer to design and build the proposed new bridge at Harwood over the Clarence River in New South Wales.  The new 1.5 kilometre bridge is being built 70 meters downstream of the existing bridge and is the longest of more than 100 bridges to be built as part of the 155 km Woolgoolga to Ballina Pacific Highway upgrade.

Key Features of the project.

  • Design and construction of a new 1.5 kilometre bridge over the Clarence River, about 30 metres downstream from the existing bridge. The length of the bridge over the Clarence River will span 620 metres, with a vertical clearance above the river of at least 30 metres for marine traffic to pass.
  • The new bridge will be a dual carriageway bridge, with two lanes in each direction including local road works at the northern and southern abutments.

When approached by the team at Pacifico (Acciona and Ferrovial JV) to assist with the critical element of forming up the columns and headstocks Acrow Formwork & Scaffolding was quick to respond coming up with an innovative fully engineered solution, that pushed the boundaries of conventional formwork.

“Harwood Bridge was a complex design and supply project that took Acrow out of its comfort zone and pushed the boundary into more complex temporary works to provide the client with an all in one solution they were after. Through many hours of design and coordination we were able to provide the client with a simple and efficient system that was overall safe to use with the majority of issues resolved though meticulous planning by all parties involved before work began”
