Stuart Highway
Stuart Highway is one of Australia's major highways. It runs from Darwin, in the Northern Territory, via Tennant Creek and Alice Springs, to Port Augusta in South Australia; a distance of. Its northern and southern extremities are segments of Australia's Highway 1. The principal north-south route through the central interior of mainland Australia, the highway is often referred to simply as "The Track".
The highway is named after Scottish explorer John McDouall Stuart, who was the first European to cross Australia from south to north. The highway approximates the route Stuart took.
Route description
Overview
Stuart Highway runs from Darwin, Northern Territory, in the north, via Tennant Creek and Alice Springs, to Port Augusta, South Australia, in the south – a distance of.The Royal Flying Doctor Service uses the highway as an emergency landing strip and sections of the highway are signed to that effect. These sections of highway have been specially selected and prepared for the landing of aircraft which only takes place after the piece of road has been closed by the police.
There are petrol and other facilities available at reasonable intervals and more frequent rest stops. Some of the rest stops are located at scenic points with information boards, but others are little more than a picnic table and a rubbish bin in an otherwise deserted area.
Northern Territory
The Northern Territory section of the Stuart Highway starts from the edge of the Darwin central business district at Daly Street and continues as a dual-carriageway to the Arnhem Highway in Howard Springs. The highway continues south passing the Kakadu Highway to the Victoria Highway at Katherine.At Daly Waters, the route number changes from National Highway 1 to National Highway 87. The highway then continues south passing the Roper Highway, the Carpentaria Highway and the Buchanan Highway to the Barkly Highway at Tennant Creek. The highway continues south into Alice Springs passing the Plenty Highway. It passes through the Macdonnell Ranges and finally crosses the Northern Territory/South Australia border south of Kulgera.
The highway was only fully sealed in February 1987 as part of the Australian Bicentenary roadworks programme. There are no police patrolling the majority of this remote highway and until the end of 2006 there was no speed limit outside towns and other built-up areas on the Northern Territory part. The bulk of the Northern Territory's population not living in Darwin lies along its track.
South Australia
At the Northern Territory/South Australia border the route number changes from 87 to National Highway A87. The Stuart Highway passes through the Far North region to Port Augusta. The highway passes through the Woomera Prohibited Area where travellers may not leave the road. The highway continues south-east towards Adelaide.History
Background
led the first successful expedition to traverse the Australian mainland from south to north and return, through the centre of the continent, in 1861–1862. In 1871–72 the Australian Overland Telegraph Line was constructed along Stuart's route. The principal road from Port Augusta to Darwin was also established on a similar route.A track developed along the route of the telegraph, and by 1888 the road between Adelaide and Alice Springs was well known. Several wells along the route provided water, although these could run dry or be contaminated by dead animals, resulting in sections as long as without water.
The route was traversed by motor vehicles in the 1920s. While passable, sections of the road could be sandy, boggy, washed away in the winter, or rugged with boulders. Several creek crossings were required, though few were difficult. North of Alice Springs the road was in comparatively good condition, with sections allowing speeds of up to.
Highway planning and construction
With the onset of World War II, supply roads leading to the north of the country were considered vital by the Federal Government.A central north–south highway was planned to connect the railheads at Alice Springs and Birdum,
with surveying completed in August 1940. The task of constructing the highway was split between the Main Roads Departments of three states, to ensure completion before the next wet season. New South Wales would construct the northern section of, Queensland the central section of, and South Australia the southern section of.
The Alice Springs–Birdum road was completed by December 1940, – upgraded from an often impassable track to an all-weather sealed highway that could cope with heavy military traffic. The highway was built in under than 90 days. In one week, was constructed, which was claimed to be a world record. The new highway, in conjunction with the railways at either end, reduced the impact of Darwin's isolation. Quick and efficient movement of military equipment and troop was possible, with the road remaining open throughout the wet season.
By March 1941, military authorities advocated extending the Alice Springs–Birdum road to Darwin. During the wet season, the road north of Birdum was impassable, which meant that a single railway line was the only connection through to Darwin. Construction was underway by October 1941, once again at a fast pace in an attempt to finish before the next wet season. The road was nearing completion in July 1942, although some sections were yet to be bitumenised.
Speed limits
There was no absolute speed limit in the Northern Territory before 1 January 2007 but maximum speed limits are now posted on some road sections. Drivers, previously, were simply required to drive at a safe speed to suit the conditions. Thus, the Northern Territory section of the Stuart Highway had no speed limits at all. The Northern Territory traffic laws were updated from 1 January 2007 to be similar to the rest of Australia. This included placing a speed limit on all roads and significantly increasing penalties for speeding.The South Australian Section is signposted as outside built-up regions, between Port Augusta and the Northern Territory border.
In October 2013 the NT Government announced a trial period of reverting to an open speed limit on the stretch between Alice Springs and Barrow Creek, beginning 1 February 2014. In September 2015, following the conclusion of the trial, a stretch of the highway had its speed limits permanently derestricted.
As of November 2016, a speed limit has been reinstated, with the maximum speed now being.
Junctions
Motor racing
Motor races have been proposed or undertaken on the highway since the 1950s.In 1994 the first and only Cannonball Run in Australia ran from Darwin to Yulara and back again. Based on similar events in the United States, this event ended in tragedy when an out of control Ferrari F40 crashed into a checkpoint south of Alice Springs, resulting in the death of the two event officials manning the checkpoint as well as the two competitors. The remainder of the race had a speed limit imposed to prevent further accidents.
Stuart Highway is the highway taken in the World Solar Challenge. The race starts in Darwin, follows Stuart Highway to Port Augusta, and then Highway 1 through to Adelaide.
