Truckies want heavy freight tunnel in South Australia

A TUNNEL under the foothills behind Springfield should be built as part of a link between the South East Freeway and South Rd, the SA Freight Council says.

When the North-South Corridor is completed, trucks will want to head straight for that route rather than weaving through the eastern suburbs, council chief executive Evan Knapp said.

"The North South Corridor is going to be transformational," he said.

In a submission to Infrastructure SA's 20-year strategic plan, the SA Freight Council proposes an alternative to the Cross Rd option.

Its South East Link route would tunnel from the arrester bed at the last downhill corner of the SE Freeway, under the foothills to emerge near the Carrick Hill estate and Brownhill Creek.

Mr Knapp acknowledged the project would likely cost billions of dollars and there would be complex elements such as bridging Brownhill Creek and getting to Springbank Rd.
