The Glenelg Tram is a 15 km (9.3 mi) route from the centre of Adelaide, South Australia to the beach-side suburb of Glenelg. It is Adelaide's only remaining tramway, running at approximately 15-minute intervals, and is part of the integrated Adelaide Metro public transport network. The service is free between North and South Terraces in the City, and along the entire length of Jetty Road in Glenelg. Apart from short street-running sections in Adelaide city centre and Glenelg, the Glenelg route is in a private reservation, providing a fast and reliable service with minimal interference from road traffic.
