North West Coastal Highway

Sealing of Shoulders - Barradale to Pannawonica Road

 

Background

North West Coastal Highway is the coastal link between the south of the State and the regional centres of Karratha and Port Hedland.

As well as being a principal freight route with triple road trains (up to 53.5 m) operating north of Carnarvon, the road also provides access to various tourist destinations, mining operations and pastoral communities.

The section of highway north of Nanutarra to Onslow turn-off while sealed 7.4 m wide has shoulders that are unsealed, which can result in excessive wear of the natural gravels and result in sever edge drop off increasing the risk of loss of control of vehicles – a significant risk for those towing caravans and boats.

The project will provide the additional sealed width (9m), reducing edge wear and drop off, in addition the sealed shoulders, will enable the installation of audible edge lines from Barradale (Yannarie River) to Onslow turn-off.

Scope of Works

The intention is to provide sealed shoulders with audible edge lines through to Pannawonica Road. Works will be undertaken in stages over the following years due to funding limitations. Stage Two of the project involves sealing between Nanutarra and the Onslow Road intersection.

 

Construction Schedule

Stage One of the project involved sealing between Barradale and 15 km south of Onslow Road intersection and was completed in August 2012, with AudibleEdgeLines being installedin the first half of 2014.

Stage Two works have been completed (some minor clean up works are still taking place). Practical completion was achieved on Sunday, 2nd August 2015. Formal handover to the Pilbara Region will occur over the coming week.

Further funding is being sought to deliver the remainder of works through further stages.
