Federal and State funds mounting to $93 million for an upgrade on Main South Road to McLaren Vale has given hope to regional councils that main arterial council roads will be next in line for funding.
District Council of Yankalilla Mayor Glen Rowlands said with the duplication of the Southern Expressway and the extension of the rail to Seaford the Fleurieu Coast has experienced easier move-ability to and from the region.
"Daily visitors and holiday travellers have increased, but more so the ability to live here and work in the north.
"With the proposed extension of the expressway to Aldinga/Sellicks, we'll experience another wave which puts a lot of pressure on our road networks, both councils and states," Mr Rowlands said.
"The state owns Main South Road through to Cape Jervis, which runs through the Yankalilla CBD and touches the Normanville main street, therefore not only the visitor and local use this road, 90 per cent of the traffic destined for Kangaroo Island also goes through our CBD and a further extension of the Southern Expressway will add significantly to the congestion."
Mr Rowlands said everything that goes to Kangaroo Island goes through the main street of Yankalilla and that includes not just tourists and buses, but all produce, fuel, grain and all the needs the Island requires.
"I don't know how long we can accommodate this volume of traffic and nothing will change until there is a fatality," he said.
"As metropolitan Adelaide gets closer, consideration of upgrading Main South Road is vital to address safety, congestion and heavy vehicle movement.
"The Fleurieu Coast seem to be the forgotten region in these conversations, yes roads to Victor Harbor, Strathalbyn, Goolwa are very important, but so is Main South Road to Penneshaw."
Mr Rowlands said the Myponga to Yankalilla section is still on the original path of "the horse and cart".
"It is a picturesque drive, but very narrow, windy and very dangerous," he said.
According to Mr Rowlands, Forktree Road which is the direct link to Carrickalinga, from Main South Road, eases some traffic, but three kilometres of this road is unsealed.
"It is in the planning process for realignment and bitumising."
In the District Council of Yankalilla's list of top priorities published ahead of the federal election, they have called for the creation of a federal highway, with B-double access, to Kangaroo Island, as well as a slow lane on Main South Road at Cape Jervis.
In the submission, council has pushed for more overtaking lands, the removal of windy curves between Myponga and Yankalilla and attention provided to the Williss Drive / Main South Road / Main Street, Normanville and flooding on Williss Drive.
"Council considers the road to be a priority road, connecting with Kangaroo Island and consideration to making it a Federal Highway with appropriate funding should be provided," the submission said.
According to statistics from the RAA between 2013 and 2017, 151 casualty crashes occurred on the 40 kilometre section of Main South Road between Old Noarlunga and Yankalilla.
Three of these were fatal. However, 85 of those accidents were on the 11 kilometre section between Victor Harbor Road and Aldinga Beach Road that is funded under Stage 1 of the duplication to the Sellicks project.
The City of Victor Harbor and Alexandrina Council are expected voice their opinions on infrastructure funding requirements in their regions.
The submission also adds that the idea behind the slow lane is to allow free-flowing traffic around the ferry terminal, as heavy vehicles use the inclining and declining route, which slows other drivers. The lack of overtaking opportunities between the terminal and Normanville often results in congestion which would be alleviated through the inclusion of the slow lane.
