Current Works

Early Works 2021

Ground Investigations are underway on the T2D Project.

In August 2020 we started a drilling and engineering survey program in areas close to South Road. We recently completed Phase One investigations, which included;

  • examining approximately 200 bore holes;
  • completing over 5 km of drilling, and;
  • conducting around 5,000 tests.

In May 2021, the Minister for Infrastructure and Transport announced the contract Award for Phase Two early works, which will begin in June 2021.

We will notify nearby local residents and businesses in advance of any activities that are planned for their area and work to keep
disruption to a minimum. The selected locations do not necessarily correspond to areas that will be impacted by the program in the final design.

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.

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

The video below helps explain the early works program in more detail.

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.

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.

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 different 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.
