Northern Expressway freeway in Adelaide, South Australia

The Northern Expressway, also known as the Fatchen Northern Expressway, is a 23 kilometre long controlled-access highway in Adelaide, South Australia. It travels from Gawler to Port Wakefield Road. The road has been built to four-lane standard and provides a faster route between Adelaide and Gawler, whilst reducing the amount of traffic on Main North Road, which passes through the heart of the northern suburbs and is interspersed with frequent traffic lights. It also allows freight vehicles to avoid residential areas and go straight to Port Wakefield Road and onto the Port River Expressway (A9) to reach the harbour at Port Adelaide.

Contents

It is a freeway standard route connecting Main North Road to the Sturt Highway, bypassing Gawler. Major exits include Angle Vale Road, Two Wells Road, Northern Expressway, Mallala Road and Horrocks Highway (formerly Main North Road). Each of these exits also have minor roads leading into Gawler.

Main North Road road in South Australia

Main North Road is the major north-south arterial route through the suburbs north of the Adelaide City Centre in the city of Adelaide, South Australia. It continues north through the settled areas of South Australia and is a total of 307 kilometres (191 mi) long, from North Adelaide to 21 kilometres (13 mi) out of Port Augusta. It follows the route established in the early years of the colony by explorer John Horrocks and was a major route for farmers and graziers to reach the capital, passing through rich farmland and the Clare Valley wine region. In 2011, the section of road between Gawler to Wilmington was renamed Horrocks Highway.

Sturt Highway Australian national highway in New South Wales, Victoria, and South Australia

The Sturt Highway is an Australian national highway in New South Wales, Victoria, and South Australia. The Sturt Highway is an important road link for the transport of passengers and freight between Sydney and Adelaide and the regions situated adjacent to the route.

Gawler is the oldest country town on the Australian mainland in the state of South Australia, and is named after the second Governor of the colony of South Australia, George Gawler. It is about 40–44 km (25–27 mi) north of the centre of the state capital, Adelaide, and is close to the major wine producing district of the Barossa Valley. Topographically, Gawler lies at the confluence of two tributaries of the Gawler River, the North and South Para rivers, where they emerge from a range of low hills.

The route was built in 1963 in an attempt to redirect traffic on the national highway out of Gawler town centre and has been upgraded and realigned several times since then.

History

The first Gawler bypass was planned in the 1950s [3] and built as a single two-lane carriageway around the town in 1963 with at-grade intersections and carried 3000 vehicles per day. [4] It ended at a tee-junction at the southern end, and followed an alignment that included what is now the southbound on-ramp and Brereton Road, Jack Cooper Drive over the Winckel Bridge, [5] and Paternoster Drive to the railway bridge.

The next advance developed the road to dual carriageway with grade-separated intersections at the southern end in the 1980s and new bridges over the Gawler River. When it was approved, the 1963 bypass was carrying 7000 vehicles per day, and 300 collisions had been recorded between 1977 and 1982. [4]

Gawler River (South Australia) river in South Australia

The Gawler River is a river located in the Adelaide Plains district of the Mid North region in the Australian state of South Australia.

Improvements to the Sturt Highway have included upgrades to the northern end of the Gawler Bypass to facilitate smooth flow between them, completed in 2010. [6]

The construction of the Northern Expressway in 2010 resulted in realignment of the northbound carriageway as part of creating a grade-separated intersection with smooth flow between the northern section of the Gawler bypass and both the Northern Expressway and the southern part of the Gawler bypass. As both roads lead broadly south, there is no provision to turn directly from one to the other.

A limited-access road, known by various terms worldwide, including limited-access highway, dual-carriageway, expressway, and partial controlled access highway, is a highway or arterial road for high-speed traffic which has many or most characteristics of a controlled-access highway, including limited or no access to adjacent property, some degree of separation of opposing traffic flow, use of grade separated interchanges to some extent, prohibition of some modes of transport such as bicycles or horses, and very few or no intersecting cross-streets.

Two-lane expressway Article collection to the topic "two-lane expressways" (Limited-access road of a specific country)

A two-lane expressway or two-lane freeway is an expressway or freeway with only one lane in each direction, and usually no median barrier. It may be built that way because of constraints, or may be intended for expansion once traffic volumes rise. The term super two is often used by roadgeeks for this type of road, but traffic engineers use that term for a high-quality surface road. Most of these roads are not tolled.
