Investigation works on the final 10.5-kilometre stretch of the North South Corridor have stepped up another gear, with the contract being awarded for further detailed geotechnical work.
On-site investigations are expected to begin in August and will be carried out across approximately 130 test sites, which have been carefully chosen to minimise impacts to motorists, businesses and residents, as practically as possible.
Golder Associates and WSP Australia have been awarded a $4.52 million contract to jointly undertake, from their Adelaide bases, the ground investigations work for the Torrens to Darlington Upgrade Project.
“We are forging ahead with this mammoth project that will underpin thousands of jobs over the next decade and massively reduce travel times and congestion on one of our busiest roads,” said Minister for Transport, Infrastructure and Local Government Stephan Knoll.
“These are necessary investigatory works to help inform our decision about the future of the biggest job creating infrastructure project in South Australia’s history.
“This geotechnical work will help provide more detail about the viability of tunnels now we have put them back on the agenda after Labor ruled them out when they were in government.
“We already have $5.4 billion on the table towards the completion of the most difficult part of this 78-kilometre continuous motorway.
“This is the final piece in the North South Corridor puzzle that will create thousands of jobs and massively reduce travel times.
“Earlier this year we opened the Northern Connector which is saving South Australians around 10 minutes on their journey.
“The Darlington project is due for completion very shortly and is cutting out five sets of traffic lights that will save motorists even more time.
“Works are ramping up on the Regency to Pym Street section of the North South Corridor which will be done in 2022, with the main bridge already beginning to be built offline.
“It’s all coming together and it’s very important we have as much information as possible to help inform the preferred option and final design.”
The number and the location of test sites are designed to inform the geotechnical and hydrogeological conditions of a wide area and gain a comprehensive picture of the underlying soil and groundwater along the alignment.
These locations do not necessarily correspond to areas that will be impacted by the final design of the project.
Advance notification will be provided to businesses or residents in the vicinity of the works.
