North West Coastal Highway is a generally north-south Western Australian highway which links the coastal city of Geraldton with the town of Port Hedland. The 1,300-kilometre-long (808 mi) road, constructed as a sealed two-lane single carriageway, travels through remote and largely arid landscapes. Carnarvon is the only large settlement on the highway, and is an oasis within the harsh surrounding environment. The entire highway is allocated National Route 1, part of Australia's Highway 1, and parts of the highway are included in tourist routes Batavia Coast Tourist Way and Cossack Tourist Way. Economically, North West Coastal Highway is an important link to the Mid West, Gascoyne and Pilbara regions, supporting the agricultural, pastoral, fishing, and tourism industries, as well as mining and offshore oil and gas production.
In Geraldton, the highway begins at a grade separated interchange with Brand Highway and roads providing access to the port and town centre. Two major roads link the North West Coastal Highway to the inland Great Northern Highway: Geraldton–Mount Magnet Road in Geraldton, and Nanutarra Munjina Road at Nanutarra, 845 kilometres (525 mi) further north. Several roads link provide access to coastal towns and attractions, including Shark Bay Road, Onslow Road and Karratha Road. With few towns on the highway, roadhouses are the only settlements for long stretches. North West Coastal Highway ends at Great Northern Highway, 30 kilometres (19 mi) out from Port Hedland.
North West Coastal Highway was created in 1944 from existing roads and tracks through remote pastoral areas. However, it was a hazardous route that could be dusty in the dry season, and boggy or washed away in the wet season. Economic growth and development in northern Western Australia prompted initial improvement efforts in the late 1940s, and a sealed road was constructed from Geraldton to Carnarvon by 1962. The impact of cyclones and seasonal flooding resulted in a realignment inland of the Carnarvon to Port Hedland section, which was constructed and sealed between 1966 and 1973, and required thirty new bridges.[3] Various upgrades have been carried out in sections across the length of the highway, including the Geraldton Southern Transport Corridor project which grade-separated the highway's junction with Brand Highway.
