August traffic switch

Wed., 29 July, 2020

On Thursday, 6 August from 7pm-6am and from Friday, 7 August, to Sunday, 9 August, the R2P Project will carry out works and implement a second traffic switch.

From Monday, 10 August, traffic will be realigned to the new South Road surface roads.

This traffic switch will allow the commencement of works on South Road to construct the structures that support the Regency Road Overpass, while allowing traffic to travel through the R2P Project area.

Where will the works be located and how long will the works take?

Works will be carried out along the North-South Motorway, Regency Road, South Road, Pym Street and adjoining local streets. Works will commence on Thursday, 6 August from 7pm-6am and again at 7pm Friday, 7 August, and continue until 7pm, Sunday, 9 August, weather permitting.

How will the works affect me?

Works will commence on Thursday, 6 August from 7pm-6am to realign northbound traffic, north of Regency Road to the new South Road surface road.

Works will then be undertaken continuously from 7pm Friday until 7pm Sunday to:

  • realign northbound and southbound traffic to the new South Road surface roads;
  • open the U-turns on South Road near Tikalara Street and Hudson Avenue, including opening a pedestrian crossing at the U-turn near Hudson Avenue;
  • remove the east-west through movement along Pym Street across South Road (from Friday night) (for alternative routes please click here);
  • remove right turns from South Road to Regency Road (Saturday night) (for alternative routes please click here); and
  • open a temporary bus only hook-turn from Regency Road onto South Road, for the new bus routes along South Road.

There will be multiple crews working over the weekend to enable the traffic switch. Key construction activities include:

  • setting up of traffic management to support all construction areas;
  • laying new asphalt at the U-turns, Pym Street and the intersection of South Road and Regency Road;
  • removing existing and paint new road line marking;
  • placing concrete and water-filled road barriers to separate roads users from the construction areas; and
  • removing existing and installation new traffic signal poles.

Some noise and vibration can be expected at times however, the works will be managed to minimise disturbance to local residents as much as practically possible.

Traffic management

Lane and speed restrictions will be required along the North-South Motorway (between Grand Junction Road and Regency Road), South Road (between Regency Road and Torrens Road), Regency Road (between Crossley Avenue and Naweena Road) and Pym Street (between Austin Street and Charron Road).

Traffic management and signage will be in place to alert road users to the changed traffic conditions. Please plan ahead and take extra care when workers are on site. Observe speed limits, lane restrictions and traffic controllers when travelling through the area.

On Saturday, 8 August, from 10pm to 9am, there will be a temporary closure of the (southbound) North-South Motorway and South Road, between Grand Junction Road and Pym Street. Advance notice and signage will be in place to advise motorists of detours. Eastbound traffic on Regency Road will be detoured via the North-South Motorway, Taminga and Naweena Roads onto Regency Road.

Southbound traffic can use Hanson Road and Churchill Road from Grand Junction Road to travel onto Regency Road for alternate routes. Local traffic can use Days Road, Naweena Road and Reo Road for alternate routes. Please click here to view the detour map.

On Saturday, 8 August from 7am to 2pm, there will be a temporary closure of the northbound service road from Torrens Road to Pym Street. Northbound traffic from the lowered motorway will be maintained with lane restrictions. Alternative access is via the North-South Motorway or Days Road.

Pym Street will be closed either side of South Road as follows:

  • west side from 7pm Friday, 7 August to 2pm Saturday, 8 August (reopened to left in and left out only); and

Bus changes

Bus routes 230 and 232 will continue to run over the weekend. Buses will travel east-west along Pym Street across South Road until last service Friday, 7 August.
