A motorist has indulged in the time-honoured South Australian tradition of driving on the O-Bahn track.

A female motorist drove her car down the Park Terrace O-Bahn tunnel on Thursday morning, entering at Gilberton before stopping.

Crews at the scene worked on attempting to removed the vehicle in the northbound lane throughout the morning.

The news comes following an incident earlier this month when a bus missed the tracks, flipping on to its side at Klemzig Interchange.
