The Glenelg tram line is a tram/light rail line in Adelaide. Apart from a short street-running section in Glenelg, the line has its own reservation, with minimal interference from road traffic.
The service is free in the city centre and along the route to the Adelaide Entertainment Centre in Hindmarsh. The service is also free along the length of Jetty Road, Glenelg to Moseley Square. Three routes in total operate on the network: Glenelg to the Royal Adelaide Hospital with select peak services that continue to the Adelaide Entertainment Centre; Glenelg to the Adelaide Festival Centre, which operates only on weekends and Adelaide Oval event days; and the Adelaide Entertainment Centre to the Adelaide Botanic Garden.
A 1.6 kilometre northern extension through the city centre opened in October 2007, extending the line from Victoria Square along King William Street and North Terrace to Morphett Street. A further 2.8 kilometre north western extension of the line along Port Road to the Adelaide Entertainment Centre opened in March 2010. A new junction and branch lines along the eastern end of North Terrace and King William Road opened in October 2018.
