Manton Street and Adam Street junction upgrade

The Manton Street and Adam Street junction upgrade will provide additional capacity for citybound traffic by adding an additional left turn lane from Manton Street into Adam Street (eastbound).

It will also improve public transport efficiency, pedestrian and cyclist safety, and access to the River Torrens Linear Path.

As part of the River Torrens to Darlington (T2D) project there will be $850 million worth of additional network and amenity upgrades along and around the final 10.5km section of South Road. These works are essential to the proper functioning of the motorway and wider road network both during and after construction of the T2D project.

Concept design

Updates made to concept design following community feedback

We would like to thank residents and the local business community for providing their valuable insights on the proposed concept design.

The junction upgrade was generally well received by the local community. The proposed additional city bound lane was overwhelmingly supported. Improving pedestrian access and safety in the precinct was also well supported.

We also heard that removing the right-hand turn from Manton Street onto Adam Street would make access to the Hindmarsh precinct difficult, particularly for larger delivery vehicles needing to divert onto Richards Street.

To resolve this, we have revised the design to retain the signalised right-hand turn from Manton Street onto Adam Street (west bound).

By retaining this signalised turn, traffic will be able to continue to access the Hindmarsh precinct directly via Adam Street and will no longer need to divert onto Richard Street.

As a result of this change, we will not proceed with the proposed Richard Street right-hand turn from Manton Street.

The second lane (city bound) on Manton Street and east-west access in both directions along Adam Street is also still retained.

Next steps

The detailed design will be finalised over the coming months, with construction due to start in mid-2024.

Project completion is expected in the third quarter of 2024 (weather permitting).

Community engagement

We are committed to working with local businesses and residents to ensure you are kept well informed during the construction process and the construction impacts are minimised.
