The 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, 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, 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. 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. ==Route description== North West Coastal Highway is the coastal route through Western Australia's remote north-west. From the Mid West city of Geraldton, the highway heads north to the small town of Northampton, and another to Carnarvon, the only large settlement along the route. It continues north-east for to Roebourne, beyond the turnoff to Karratha, and ends further east at Great Northern Highway, out from Port Hedland. Apart from Whim Creek, between Roeburn and Port Hedland, roadhouses serving the highway are the only settlements on the long stretches of rangeland expanses between these towns. The highway provides access to tourist destinations including Shark Bay, Coral Bay, and Exmouth.〔〔〔 North West Coastal Highway supports the diversified economies of the Mid West and Gascoyne regions, including mining, agriculture, fishing and tourism,〔 〕〔 〕 transitioning to primarily mining, pastoral stations and offshore oil and gas production in the Pilbara.〔 〕 The entire highway is allocated National Route 1, part of Australia's Highway 1, and parts of the highway are included in the tourist routes Batavia Coast Tourist Way (Tourist Drive 354) and Cossack Tourist Way (Tourist Drive 351).〔 〕 The vast majority of the highway is a two-lane single carriageway with a speed limit of , except in and around built up areas where it drops down to .〔 Main Roads Western Australia monitors traffic volume across the state's road network, including various locations along North West Coastal Highway.〔 〕 In the 2012/13 financial year, the recorded traffic volumes ranged from 13,350 vehicles per day west of Geraldton–Mount Magnet Road down to 370 north of Minilya–Exmouth Road. The highest percentage of heavy vehicles was 45.5%, west of Karratha Road.〔 Reports commissioned by the Royal Automobile Club of Western Australia (RAC) in 2006 and 2008 gave most of the highway a four-star safety rating out of five, but with a significant proportion rated at a three-star level. The overall highway network was generally rated as three-star or four-star, with around 10% in 2006 and 5% in 2008 receiving a two-star rating.〔 〕〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「North West Coastal Highway」の詳細全文を読む スポンサード リンク
