Manton Street and Adam Street junction upgrade
The Manton Street and Adam Street junction upgrade will provide additional capacity for city bound traffic by adding a left-turn lane from Manton Street into Adam Street (eastbound).
It will also improve 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 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 had overwhelming support. 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 that need to divert onto Richards Street.
To resolve this, we revised the design to keep the signalised right-hand turn from Manton Street onto Adam Street (westbound).
By keeping this signalised turn, traffic will be able to continue to access the Hindmarsh precinct directly via Adam Street. Traffic 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.
