Tea Tree Plaza Interchange (formerly known as Modbury Interchange) is a bus interchange operated by Adelaide Metro in Modbury, South Australia as part of the O-Bahn Busway. It is a central public transport hub for the north eastern suburbs of Adelaide.

2013 redevelopments On 24 February 2013, Premier Jay Weatherill announced a $17 million upgrade of facilities along the O-Bahn Busway, which included increased bicycle storage, real-time information screens and additional seating. As part of the upgrade, a $14 million multiple level carpark was built on the north-west corner of the Tea Tree Gully campus of TAFE SA. The carpark provides 700 spaces, 300 more than was previously available. The entrance to the carpark utilises the access road from Smart Road that was previously only used by buses entering the busway. The development is expected to meet consumer demand at the interchange until 2021. The carpark opened on 13 January 2014. However, some have criticised the move to charge non-MetroCARD holders $10, whereas those whose who have a metrocard are only charged $2.Park & Ride Ready Australasian Bus & Coach 13 January 2014Tea Tree Plaza Interchange Park & Ride Adelaide Metro
