A new link road connecting Edward Street and Raglan Avenue is now open, delivering permanent traffic improvements near Castle Plaza as part of the Department for Infrastructure and Transport’s River Torrens to Darlington (T2D) Project.

New link road now open

The new link road between Edward Street and Raglan Avenue is now open to traffic.

 The upgraded intersection includes:

• A dedicated through lane.
• A dedicated right‑turn lane at the intersection of South Road, Edward Street and the new link road.

With the opening of the link road, the following permanent traffic changes are now in place:

• The right‑hand turn from South Road into Raglan Avenue has been permanently removed.
• The signalised intersection at South Road and Raglan Avenue has been removed.
• Access to Raglan Avenue from South Road is now available via the new link road.

Ongoing Raglan Avenue works

Following the removal of traffic signals on South Road, construction continues along Raglan Avenue between South Road and the new roundabout.

To allow these works to be carried out safely, the following temporary traffic arrangements will remain in place until mid‑2026:

Night‑time closures:

• Raglan Avenue between South Road and the new roundabout is closed from 7:00pm to 6:00am.

Day‑time traffic changes:

• Raglan Avenue between South Road and the new roundabout is reduced to westbound traffic only.

These changes will support construction of new kerbing, footpaths, pavement, landscaping and lighting.

The works form part of the River Torrens to Darlington (T2D) Project and the $850 million Broader Network Upgrade, designed to improve safety and traffic flow for all road users.

Accessing the Centre

Castle Plaza and surrounding local businesses remain accessible at all times via South Road and Raglan Avenue.

Pedestrian and cyclist access may be adjusted during works, with signage in place to guide safe movement through the area. 

Emergency vehicle access will be maintained at all times.

Temporary Raglan Avenue car park changes

Raglan Avenue entrances to the Castle Plaza car park will be closed from 7pm Sunday 26 April for approximately two weeks. Detours inside and outside of the Centre will be in place to assist with traffic navigation.

Bus stop changes

Bus Stop 15 on Raglan Avenue (north and south sides) has been relocated to new permanent locations.

Please follow onsite signage and visit the Adelaide Metro website for service updates.

What’s next

Works along Raglan Avenue, South Road and Price Street will continue and include kerbing, driveways, footpaths, landscaping, drainage, lighting and service relocation.

Construction of the new signalised intersection at the Castle Plaza entrance on South Road and Price Street is expected to commence in late April and continue through to mid‑2026, weather permitting. Further updates will be provided closer to commencement.
