She said the road closure would put more pressure on the Verran Terrace and Mortlock Terrace intersection, with people likely to drive along Coronation Street.

“I do not think the other roads are going to handle it unless they are going to change something.”

Port Lincoln resident Ib Svane said traffic from the proposed retirement village would also be an issue.

He was also concerned the road would further isolate the marina from Port Lincoln and that fishing and aquaculture companies would find the road closure difficult.

Along with more people living at the marina because of the development, the new Lutheran school would also add to the problem.

In a report to the Port Lincoln City Council, director of operations Geoff Dodd said the largest impact would be on Stamford Terrace, which would see traffic volumes almost triple from 2800 to 8200 vehicles a day, and increased travel distances for existing residents in the marina area.

Mrs Fitzgerald said the road closure would inconvenience children who rode their bikes to school or Ravendale, and those people who walked to the Port Lincoln Leisure Centre.

“You are going to have trucks rolling through a residential area. The noise of trucks right through a residential area, and they start well before the sun is up.”

A public meeting will follow the consultation period before the Port Lincoln City Council considers all submissions and makes a final request to the surveyor general, who would have to approve the closure.
