Taramakau Bridge artist impression

Project introduction

A new two-lane bridge will be built downstream of the existing one-lane Taramakau Bridge. A section of SH6 will be realigned and an overpass built to take traffic over the railway line. An off-road cycle and pedestrian link will also be built.

The new Taramakau Bridge project

The new two-lane bridge will be built between Greymouth and the Kumara Junction, 30 metres downstream of the existing single-lane road and rail bridge.

The new bridge will be 250 metres long, 10 metres high and 15 metres wide. The project will see a section of State Highway 6 realigned and an overpass built to take road traffic over the railway line.

A 2.5 metre wide, off-road cycle and pedestrian facility that will link into an existing cycle track will also be built.

The existing bridge will remain in place and will be used solely as a rail bridge. The clip-on cycle and walking bridge will be installed at another yet to be determined site.

This is a Government Accelerated Regional Roading Project (external link) . Fulton Hogan has been awarded the contract for the project. Work is expected to be complete by the end of 2018.

Project benefits

  • The new two-lane Taramakau Bridge is a long awaited project for the West Coast that will provide significant improvements for travellers in terms of safety, travel times and journey experience.
  • The bridge is on an important route, connecting Greymouth to Christchurch, via Arthurs Pass, and to Hokitika and onwards to Haast and the Otago region.
  • The existing single lane bridge causes traffic congestion, with vehicles having to queue to cross the 220 metre long structure.
  • The new two-lane bridge means local business operators, freight vehicles and residents will no longer have to wait at each end on their daily commutes.
  • The cycle and pedestrian path will link into existing facilities, making it easier and safer to walk and bike around the area.
  • The cycle links will play a part in the growing tourism opportunities developing in the West Coast such as the Wilderness Trail.
  • Rail traffic will remain on the existing bridge, and this separation of road, rail and cycling/pedestrian traffic will improve both safety and efficiency.

Taramakau Bridge piling and installation of super-tee beams

Good progress has been made on the Taramakau Bridge. Watch how the piling and installation of super-tee beams has progressed over summer months.
