Commuter route
In the metropolitan area, Main North Road is a major commuter route to the central business district in the Adelaide city centre.
The portion of Main North Road between the city centre and Mawson Lakes is a 15-minute public transport 'Go Zone', with the maximum wait for a bus being 15 minutes during peak times (7:30 am – 6:30 pm weekdays) and 30 minutes on weekends and evenings.[5] Bus routes via Main North Road generally begin with the prefix "22x". The bus service is provided by SouthLink for Adelaide Metro.
History
Main North Road previously continued north past Gawler through Tarlee, Clare, Gladstone and Wilmington, South Australia, then via Horrocks Pass to end at Winninowie, following the route established in the early years of the colony by explorer John Horrocks as 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 Wilmington and Gawler in SA's mid-north was renamed Horrocks Highway – to honour John Horrocks, an early explorer and pioneer in the region[6] – and the section between Wilmington and Winninowie re-declared as Horrocks Pass Road, with the existing declaration of Main North Road truncated to officially begin at Gawler instead.
Main North Road was allocated National Routes 1 (between Gepps Cross and North Adelaide) and 20 (between Gawler and Gepps Cross) in 1955. The Whitlam government introduced the federal National Roads Act 1974,[7] where roads declared as a National Highway were still the responsibility of the states for road construction and maintenance, but were fully compensated by the Federal government for money spent on approved projects.[7]: S7 As an important interstate link between the capitals of Adelaide and Western Australia, Main North Road was declared a National Highway in 1974, and was consequently re-allocated National Highway 1 between Gepps Cross and North Adelaide; National Route 20 was also later declared a National Highway in 1992 as part of the interstate link between Adelaide and New South Wales, and also re-allocated as National Highway 20 between Gawler and Gepps Cross. With the state's conversion to the newer alphanumeric system in 1998, its route numbers was updated to National Highway A1 between Gepps Cross and North Adelaide (and later to just route A1 in 2017), and National Highway A20 between Gawler and Gepps Cross, with route B19 declared along the old alignment through southern Gawler from Gawler Bypass to Barossa Valley Way.
In late 2010 when Northern Expressway was completed, National Highway A20 was diverted to the new road as National Highway M20: Main North Road and the southern section of Gawler Bypass Road were then designated as route A52. In late 2016, the Northern Expressway was designated M2, and the designation of Main North Road was reverted back as route A20 to Gepps Cross.[8]
