Great Northern Highway Realignment and Wallwork Road Bridge

Port Hedland

 

Overview

On behalf of Main Roads, John Holland Group has realigned Great Northern Highway around the Wedgefield industrial area in Port Hedland.

The new alignment opened to traffic on 17 June 2014 and was officially opened on 23 July 2014 by Deputy Prime Minister Warren Truss and Pilbara MLA Brendon Grylls.

Construction started in late 2012 and already John Holland has completed the new Wallwork Road Bridge, which was added to the scope of work in mid-2013 at the request of the Town of Port Hedland. The rest of the project will be finished by mid July, although traffic will start using the new alignment under restricted conditions in mid-June.

To be fully complete by Mid-August, this project will deliver many benefits to the Port Hedland community, including:

  • Reduced road train incidents with local traffic;
  • Improved road safety;
  • Improved access to new port and harbour areas; and
  • Improved traffic flows between Port and South Hedland.

We are also developing an Intelligent Transport System for the rear of Wedgefield. This will include an early warning for road train operators approaching the intersection of the new highway with Pinga Street, to minimise the need for emergency braking.

The realignment project was jointly funded by the Federal and State Governments.

 

Scope

The concept for the realignment project was developed in close consultation with local industry, stakeholders and the community.

The scope included:

  • Approximately 8 km of new road;
  • A major interchange at the Broome turn-off, enabling uninterrupted flow for local traffic over Great Northern Highway;
  • New at-grade intersection with Utah Point Road to provide access to the western port area;
  • New link to South Hedland (Hamilton Road);
  • A cultural interpretative bay overlooking the rear of the harbour;
  • New road bridge over the BHP rail line;
  • Two new low level bridges over South Creek;
  • New road embankment across low lying areas;
  • Associated drainage, including culverts, to maintain tidal flows;
  • Access to Wedgefield industrial area via a new connection to Pinga Street north;
  • Access to the port's proposed area of development to the north of Wedgefield, where BHP reclaimed dredged spoil has been deposited;
  • Access to Landcorp's proposed area of development to the east of Wedgefield; and
  • Public art and landscaping.

In mid-2013, at the request of the Town of Port Hedland, the new Wallwork Bridge was also added to the project.

Project Rationale

Port Hedland is the biggest volume port in Australia and it continues to grow in line with increased mining activity in the state's north-west. To cope with this growth the port is planning additional berths to the south west of its current location.

The amount of traffic on the Port to South Hedland link has also grown by 25 per cent over the past three years and the road is currently servicing about 15,000 vehicles per day. This growth is creating increased conflict between heavy haulage vehicles and local traffic and often causes delays at major intersections.
