A review has been requested into the Eyre Peninsula's grain strategy with the Cape Hardy deep sea port as an option to reduce traffic impact on Port Lincoln.
Eyre Peninsula Cooperative Bulk Handling called for the review following the recent announcement of grain transport discontinuing on the Eyre Peninsula Rail Network past May 31.
Concerns have been raised about the impact this will have on local roads with potentially up to 30,000 trucks movements per year.
Cooperative spokesperson Bruce Heddle said a review was necessary and must include Cape Hardy as a future port to reduce truck numbers into Port Lincoln.
"Improving road infrastructure is important but it will only reduce the time it takes to shift the grain, not reduce truck numbers," he said.
"Without considering new options, the number of trucks travelling in and out of Port Lincoln at peak times of the year is going to have a substantial impact."
The cooperation believes the development of the Cape Hardy port could alleviate traffic congestion in and around Port Lincoln as well as provide competition for exports in the region.
The project also has the support of Regional Development Australia Whyalla and Eyre Peninsula.
Chief executive officer Dion Dorward said looking for a transport solution for grain and other commodities was at the forefront of the organisation's thinking at the moment.
"That's why we've been so strong in our desire to see an alternative multi-commodity deep sea port on eastern Eyre Peninsula at Cape Hardy connected by (standard gauge) rail to the Australian Rail Network at Whyalla," he said.
"We've been in constant discussions with Iron Road and potential users of Iron Road's port at Cape Hardy."
Mr Dorward said Cape Hardy was supported because it had approvals in place, had good land area for multiple industries to use and was well placed in terms of access to main highways, heavy grain growing areas and mining areas.
