Completion of O-Bahn Busway

Date: August 20, 1989 • Location: Adelaide, Australia

The final stage of the O-Bahn Busway in Adelaide, South Australia, was finished, completing at the time the world's longest and fastest guided busway, with buses (example pictured) travelling 12 km (7.5 mi) at speeds of up to 100 km/h (62 mph).

The O-Bahn Busway is a guided busway that is part of the bus rapid transit system servicing the northeastern suburbs of Adelaide, South Australia. The original O-Bahn system is the one in the German city of Essen, and it was conceived by Daimler-Benz to enable buses to avoid traffic congestion by sharing tram tunnels.
