Project Overview  


Note: Concept for illustration purposes only.

The O-Bahn City Access Project builds on the State Government’s significant investment in a stronger public transport network and the government is committed to delivering the best possible outcome for our great city.

The primary objective of the O-Bahn City Access Project is to improve travel times and reliability for users of the O-Bahn service between the end of the busway at Gilberton and Grenfell Street and to reduce traffic congestion and delays, particularly on the Inner Ring Route.

The project will extend the O-Bahn system from the end of the busway at Gilberton into the cross-city priority (bus) lanes on Grenfell Street. The project will include the creation of centrally aligned priority bus lanes along Hackney Road and a dedicated bus tunnel from adjacent the National Wine Centre to near Grenfell Street, providing quicker, more reliable access for O-Bahn buses into the city.

The Department of Planning, Transport and Infrastructure (DPTI) has awarded the design and construction of the O-Bahn City Access Project to McConnell Dowell (MCD) Australia. Around 450 jobs will be created over the life of the project which is being conducted in line with South Australia’s Industry Participation Policy to provide important job opportunities for local South Australian businesses.

Works are underway with project completion planned for late 2017.
