Updates and announcements

Work started on the 195 metre long bridge over the railway line this month which will connect the Oxley Highway with Warrumbungle Street.

Work on the supports for the bridge foundations started on Monday 4 March and is expected to take up to three months to complete, weather permitting.

How the bridge will be built

The new bridge over the Mungindi Rail Line will be built using piling rigs and cranes which are supported by temporary piling platforms.

Building the new bridge will involve:

  • building temporary piling platforms
  • setting up heavy plant including piling rigs and cranes
  • delivering and storing precast concrete components for building the bridge
  • carrying out bored piling
  • pouring concrete for the piles
  • lifting bridge buliding components into place
  • asphalting and bridge finishing work including installing guard rails and pedestrian/cycleway.

Piling for the new bridge

Piling is the first stage of building the new bridge and will start on Monday 4 March. To create a solid foundation, 23 bored piles will be installed to provide supports for the bridge.  Bored piling involves boring holes in the ground, installing steel casings and reinforcement and filing the bore hole with concrete to form a pile.

Work will start with the arrival and setting up of equipment including piling rigs and mobile cranes and building the temporary piling platforms.

Traffic changes on Warrabungle Street

Upcoming work includes rebuilding Warrabungle Street between Little Barber and New Streets and relocation of major services on Warrabungle Street near the location of the new bridge.

Work will started Monday 14 January 2019 and is expected to take up to 12 months to complete, weather permitting.

Warrabungle Street between Little Barber and New Streets is temporary closed during this time to ensure the safety of motorists and workers. Further information, including the detour map can be found in the notification (PDF, 594Kb).

Project background

The new bridge will provide an unrestricted Higher Mass Limit (HML) freight route through Gunnedah and improve local traffic efficiency and road safety. The new route replaces the existing New Street level crossing which will be permanently closed as part of this project.

This project is designed to improve road freight productivity by replacing or upgrading bridges across regional NSW.

A range of technical, environmental and social investigations and concept designs were undertaken to develop and assess the options for a second road over rail bridge.

The new bridge will be built west of the Gunnedah Maize Mill to link the Oxley Highway with Warrabungle Street. In addition to building a new bridge, the project includes: 

  • upgrade of the Oxley Highway roundabout
  • new roundabout at the intersection of Warrabungle and Conadilly streets (completed in December 2015)
  • new intersection of Warrabungle and Barber streets
  • shared path for cyclists and pedestrians.

A new roundabout at the intersection of Warrabungle and Conadilly streets was completed and opened to traffic in December 2015.

Gunnedah Shire Council delivered the roundabout, which is early work for the second road over rail project, on behalf of Roads and Maritime Services.

The new roundabout will ensure efficient traffic flow across the new bridge, which is in the detailed design phase.
