In 2017, another stage of expansion was announced, adding a four-way tram junction at the intersection of North Terrace, King William Street and King William Road. One further stop would be provided north of that junction, adjacent to the Adelaide Festival Centre, and three to the east of it near the South Australian Museum, University of Adelaide and East End at the new eastern terminus in front of the old Royal Adelaide Hospital. The project was expected to cost $80 million with the contract awarded to a joint venture of Downer Rail and York Civil. Preliminary works began in July 2017 with major works commencing in October. The extensions opened on 13 October 2018, seven months behind schedule, with the stop at the end of the eastward line known as Botanic Gardens owing to its proximity to Adelaide Botanic Garden.
