Ensuring good investment into the local road network is a priority for nominees for the federal seat of Grey as the end of grain haulage by rail approaches.
Last week Viterra announced it would not be renewing its rail grain haulage agreement with Genesee and Wyoming Australia past its expiry of May 31.
Concerns have been raised across the region on what impact this shift would cause on local roads.
Member for Grey Rowan Ramsey said the announcement was sad news but was an accurate measure of a changing world.
He said he already had discussions with Federal Transport and Infrastructure Minister Michael McCormack and state minister Stephan Knoll and would push for each to make a "substantial commitment" to upgrading Eyre Peninsula road infrastructure.
"There will be a range of urgent issues which need to be addressed including utilising the rail corridor for a haul road on the western access to Port Lincoln and the sooner we get started the better," he said.
Centre Alliance candidate for Grey Andrea Broadfoot said there had been no release of information on economic and social impacts and no commitment as yet on infrastructure requirements for road upgrades, maintenance and renewals.
"I call on state and federal governments to guarantee us that Eyre Peninsula road and freight infrastructure investments will be planned and implemented in a way that doesn't negatively impact on the economic, social, safety and livability standards of the region," she said.
Ms Broadfoot said if elected she would strongly advocate for the region's infrastructure and community needs and this issue was a key example of what needed to be done.
Greens candidate Candace Champion said the decision by Viterra would cause a huge structural adjustment and the transition to total road haulage would also drive up greenhouse gas pollution.
"Viterra need to immediately make clear to the community how they are intending mitigate the impact of an extra 30,000 truck movements per year," she said.
"We should do everything to keep freight on rail, it’s clear that governments have dropped the ball."
"Australia needs a national transport plan to ensure that we don’t let private companies dictate the future of our region and we can move to a zero emissions future."
