Member for South West Coast Roma Britnell said her office had been inundated with calls from people concerned their presence on the Princes Highway between Warrnambool and Allansford may result in more accidents.

"I am not against wire rope barriers," Ms Britnell said.

"The concept is to save lives when they are appropriately placed but what I question is why are they not placed strategically?

"They have them where there are no trees and they haven't got them in places where there are trees."

Ms Britnell said a number of people had contacted her concerned about being forced to use the Jubilee Park Road intersection.

Ross Burke said he feared he or someone else would have an accident performing a u-turn at the intersection because it was in a dip and oncoming traffic was hard to see because they were travelling up a hill.

"If you sit at the intersection and look out, your line of sight is bad," Mr Burke said.

"You've got cars coming at you travelling 100km/h around a sweeping bend and up a hill.

"You don't see them until the last minute."

Mr Burke said it wasn't just people performing u-turns who would be at risk of an accident.

He said there was a high volume of traffic travelling to and from Jubilee Park.

"It's not just us it's caravans and cars with boats," Mr Burke said.

Mr Burke was previously able to do a u-turn closer to his home on a straight stretch of road.

But this intersection has been blocked by wire rope barriers.

Mr Burke said he didn't want to have to travel further towards Allansford every time he wants to drive to Warrnambool.

He urged the state government to consider introducing technology that advises oncoming traffic to slow down if a vehicle is approaching.

Ms Britnell said the state government should have learnt after some wire rope barriers were removed in other areas due to public outcry.

"This has not enhanced public safety, it has compromised it," she said.

"If your view is obstructed and you cannot see oncoming traffic when you are pulling out - there is only one logical conclusion - the risk of an accident is increased."

Regional Roads Victoria director Scott Lawrence said the authority was making the Princes Highway between Panmure and Warrnambool safer for the thousands of drivers who used it every day.

"As part of these works we're installing additional flexible safety barriers on the left-hand side and centre of the road in high-risk locations, to reduce the risk of head-on and run-off-road crashes - the two most common types of deadly collisions on high-speed Victorian roads," Mr Lawrence said.

"These upgrades also include a new left-hand deceleration lane for vehicles turning into Jubilee Park Road, making it easier and safer for drivers to turn."
