The O-Bahn City Access Project impacts land under the care, control and management of Adelaide City Council and the proposed new infrastructure and modifications to land includes:
- An underground tunnel that passes under Rundle and Rymill Parks and under Rundle Road
- The tunnel portal and ramp that brings the O-Bahn back up to ground level in Rymill Park to join the normal road network at the junction of East Terrace and Grenfell Street
- The re-alignment of East Terrace
- Modifications to Rundle Road
- A new pedestrian and cycle bridge over the River Torrens adjacent to Hackney Road.
In addition to the construction of the O-Bahn infrastructure, the project will:
- Modify the layout of East Terrace and Rundle Road including modifications to the cross section of Rundle Road to improve pedestrian and cycling facilities as well as modifications to on-street parking layouts
- Develop a high quality design response to remediate areas of the Park Lands that have been impacted by the project while respecting and enhancing the existing cultural and heritage aspects.
The request from the Minister for additional space in the Park Lands (See Amended Construction Licence Plan Proposal) will be used to access the tunnel, provide for efficient vehicle movements and provide for service relocations. The additional areas have been requested to reduce the impacts on trees within the Park Lands.
It is anticipated that the additional areas contained within the Amended Construction Licence Plan Proposal will only be occupied for the following length of tenure:
- Support bridge area - 8 months
- Rymill Park South - 12 months
- Rymill Park North - 5 months
Consultation has concluded.
