Less congestion, faster O-Bahn in $160m project

CONNECT - Message from the Chief Executive

25 February 2015

A revised $160 million proposal has been unveiled for a guided bus tunnel from Hackney Road to the city.

The State Government’s proposal will provide quicker, more reliable access for O-Bahn buses into the city and will reduce congestion on Adelaide’s Inner City Ring Route.

The project will also dramatically transform the city’s East End and provide opportunities to enhance the East Parklands.

The plan includes a 500-metre bus tunnel from Hackney Road to a changed Rundle Road providing a quicker and more reliable service for Adelaide’s most patronised public transport service.

The improved plan will have numerous benefits including:
- Better travel times for O-Bahn bus passengers - on average, daily bus commute times reduced by seven minutes
- Increased capacity and reduced congestion on Adelaide’s Inner City Ring Route
- Closing Rundle Road returning more than 3000 square metres of land to Rundle Park
- Significant improvements to the East End precinct
- Support about 450 jobs during construction
- Provide for future EastLink tram corridor
- Strong benefit cost ratio

The project is part of a plan to get more people on to public transport and convince them to leave their cars at home to reduce congestion and carbon emissions in and around the city.

More than 31,000 people use the O-Bahn on working days, making it the most popular public transport network in Adelaide.

Each year commuters make more than eight million journeys on the O-Bahn which is about the same number as those who use the city’s two busiest rail services - the Seaford and Gawler lines – combined.

The closure of Rundle Road and realigning it further to the south will return more land to the East Parklands and enhance the space.

It will be transformed into one of Adelaide’s premier outdoor event spaces that is expected to attract other festivals and events.

By closing Rundle Road more than 3000 square metres of land will be returned to Rundle Park.

An extensive stakeholder and community consultation process, including information sessions around Adelaide including in the Parklands, has begun.

South Australians will have the opportunity to put forward their views on the revised proposal and make sure we are delivering the best possible outcome for the city.

During the public consultation process information sessions will be held in the Tea Tree Gully Library on March 18, Rundle Mall on March 19 and the Adelaide Bowling Club on March 21.

The project information, including graphic visualisations, is available at:

Members of the public can also provide feedback on the proposal at the website, by emailing the project team at or by phoning the enquiry line on 1300 443 198.

The public consultation period ends on March 31.
