Being centrally located on the Australian mainland, Adelaide forms a strategic transport hub for east–west and north–south routes. The city itself has a metropolitan public transport system managed by and known as the [[Adelaide Metro]]. The Adelaide Metro consists of a contracted bus system including the [[O-Bahn Busway]], [[Railways in Adelaide|7 commuter rail lines]] (diesel and electric), and a small tram network operating between inner suburb [[Hindmarsh, South Australia|Hindmarsh]], the city centre, and seaside [[Glenelg tram line|Glenelg]]. Tramways were largely dismantled in the 1950s, but saw a revival in the 2010s with upgrades and extensions.

Road transport in Adelaide has historically been easier than many of the other Australian cities, with a well-defined city layout and wide multiple-lane roads from the beginning of its development. Adelaide was known as a "twenty-minute city", with commuters having been able to travel from metropolitan outskirts to the city proper in roughly twenty minutes. However, such arterial roads often experience traffic congestion as the city grows.<ref>{{cite web|title=Metro Malcontent – The Twenty Minute City No More |work=Royal Automobile Association, South Australia |year=2005 |url=http://www.raa.net/download.asp?file=documents\document_677.pdf |access-date=28 December 2008 |url-status=dead |archive-url=https://web.archive.org/web/20090115022910/http://www.raa.net/download.asp?file=documents%5Cdocument_677.pdf |archive-date=15 January 2009  }} (1.18MB)</ref>

The Adelaide metropolitan area has one freeway and four expressways. In order of construction, they are:
* The [[South Eastern Freeway]] (M1), connects the south-east corner of the Adelaide Plain to the Adelaide Hills and beyond to [[Murray Bridge, South Australia|Murray Bridge]] and [[Tailem Bend]], where it then continues as National Highway 1 south-east to Melbourne.
* The [[Southern Expressway (Australia)|Southern Expressway]] (M2), connecting the outer southern suburbs with the inner southern suburbs and the city centre. It duplicates the route of [[South Road]].
* The [[North-South Motorway]] (M2), is an ongoing major project that will become the major north–south corridor, replacing most of what is now [[South Road]], connecting the [[Southern Expressway (Adelaide)|Southern Expressway]] and the [[Northern Expressway]] via a motorway with no traffic lights. As of 2024 the motorway's northern half is complete, connecting the Northern Expressway to Adelaide's inner north-west; the section running through Adelaide's inner west and inner south-west will begin major construction in 2025 with completion estimated for 2031.<ref>{{Cite web |title=About construction - River Torrens to Darlington - Department for Infrastructure and Transport |url=https://www.t2d.sa.gov.au/construction/about-construction |access-date=2024-06-28 |website=www.t2d.sa.gov.au |language=en}}</ref>
* The [[Port River Expressway]] (A9), connects Port Adelaide and [[Outer Harbor, South Australia|Outer Harbor]] to Port Wakefield Road at the northern "entrance" to the metropolitan area.
* The [[Northern Expressway]] (Max Fatchen Expressway) (M2), is the northern suburbs bypass route connecting the Sturt Highway (National Highway 20) via the [[Gawler Bypass]] to Port Wakefield Road at a point a few kilometres north of the Port River Expressway connection.
* The [[Northern Connector]], completed in 2020, links the North South Motorway to the Northern Expressway.

The Adelaide metropolitan area has two commercial airports, [[Adelaide Airport]] and [[Parafield Airport]]. Adelaide Airport, in Adelaide's south-western suburbs, serves in excess of 8 million passengers annually.<ref name="Adelaide Airport">{{cite web|url=http://www.adelaideairport.com.au/corporate/wp-content/uploads/2014/11/nr-8-million-pax-01.17-v2.pdf|title=Adelaide Airport reaches 8 million passengers in 2016|date=16 January 2017|publisher=Adelaide Airport Ltd. media release|access-date=23 April 2017|archive-url=https://web.archive.org/web/20170320061749/http://www.adelaideairport.com.au/corporate/wp-content/uploads/2014/11/nr-8-million-pax-01.17-v2.pdf|archive-date=20 March 2017|url-status=live}}</ref> Parafield Airport, Adelaide's second airport {{convert|18|km|mi|abbr=off}} north of the city centre, is used for small aircraft, pilot training and recreational aviation purposes. Parafield Airport served as Adelaide's main aerodrome until the opening of the Adelaide Airport in February 1955. Adelaide Airport serves many international and domestic destinations including all Australian state capitals.

Adelaide is also home to a military airport, known as [[RAAF Base Edinburgh|Edinburgh Airport]], located in the northern suburbs. It was built in 1955 in a joint initiative with the United Kingdom for weapon development.
