Works

Early Works Update – December 2020

We’ve started Ground Investigations on the Torrens to Darlington (T2D) Project.

In August 2020 we started a drilling and engineering survey program in areas close to South Road.

The information from these investigations will help refine and inform the final design and determine the exact locations of the tunnels.

Drilling Program

The drilling program involves using a drill rig to drill boreholes into the ground to collect samples so we can test local geotechnical and hydrogeological ground conditions.

During Phase 1 we`ll set-up approximately 200 drilling sites and conduct around 5000 tests along the corridor.

Drill locations have been carefully selected to minimise impacts to road users, businesses and residences as much as possible while ensuring we gather this crucial data, however in some cases unavoidable short term road closures are required. Phase one drilling program will conclude early 2021 with Phase two continuing through to late 2021.See Current Activities below for exact locations and dates and times.

Phase one ground investigations will continue in early January and February 2021. 

We’ll set-up temporary work sites in the following suburbs with properties impacted directly notified in advance:

  • Black Forest
  • Clarence Gardens
  • Clarence Park
  • Clovelly Park
  • Edwardstown
  • Glandore
  • Hilton
  • Keswick
  • Melrose Park
  • Mile End South
  • Richmond
  • St Marys
  • Torrensville

Detours, signage and traffic controllers will be in place to manage traffic flow and ensure motorists, cyclists and pedestrians are able to safely navigate around our work areas.

Surveying

Our engineering survey teams are on ground along the corridor.

The survey teams are collecting information on kerbs, footpaths, underground and overhead services and any other relevant features within the existing road corridor. The information collected via the use of surveying personnel and electronic equipment, will aid in the development of the design.

In some instances as part of the surveying works, you may notice line marking, identified via coloured paint, so you may notice difference symbols painted onto the footpaths and roadways.

There should be no impact to residences or businesses, whilst undertaking these works and the extent of the survey works and/or markings on the ground do not necessarily correspond to areas impacted by the project in the final design.
