On 8 December 1975, the role of the MTT was assumed by the Bus & Tram division of the State Transport Authority. In 1994 the State Transport Authority in turn was dissolved and government public transport services were transferred to TransAdelaide, a publicly owned corporation. A partial tendering of bus services followed. The 2000 round of tenders saw the end of TransAdelaide's direct operation of bus services in its own right, and the Department of Transport, Energy & Infrastructure took control, applying the Adelaide Metro brand across all road passenger transport operators, appearing to the public as a unified network, with common livery, timetable designs and a city information centre.
