RTA to look at options for new bridge over Burrill Lake

THERE could finally be light at the end of the tunnel for Burrill Lake residents, with a new study set to provide a series of options for the upgrade of the troublesome Princes Highway causeway.

The Roads and Traffic Authority held an inspection of the bridge over Burrill Lake last month and is investigating a number of possibilities for its upgrade or replacement.

Residents have been calling for the causeway to be replaced for almost 20 years, claiming it is a major cause of siltation and weed build up in the channel.

Built in 1957, the causeway has been at the centre of a long running debate over the lake's intermittent closure, and the possibility that it could soon be replaced has been welcomed by residents including Colin Treweeke.

Mr Treweeke told the Times he had not heard about the RTA's plans and said he hopes the community will be properly consulted before any proposal gets the green light.

An RTA spokesperson told the Times an inspection of the bridge was carried out on February 5.

"The RTA is currently investigating the long-term future of the bridge over Burrill Lake," the spokesperson said.

"The bridge is an important link on the key transport route in south eastern NSW and is used by around 6,100 vehicles a day, increasing to 11,320 vehicles a day during peak holiday periods.

"The RTA has started investigating which future options are technically feasible so that it can start constructive consultation with the community and stakeholders."

The spokesperson told the Times the RTA is "at the start of a long process of investigations and consultation that will ultimately secure the long-term future of this important link in the highway".

Mr Treweeke believes the causeway should be replaced with a bridge that fully spans the lake channel and does not hinder water flow.

"I would like to see a proper bridge constructed to the east of the current causeway sooner rather than later," he said.

"There also need to be a safer pedestrian footpath across the lake.

"At the moment there's no barrier between highway traffic and pedestrians."

He said the bridge is in very poor condition and is in urgent need of an upgrade.

"I think the people of Burrill Lake will welcome a new bridge."

The news comes almost 20 years after villagers began campaigning for the replacement of the causeway, with a blockade of the Princes Highway attracting national media attention.

It was claimed then, as it is now, that the causeway restricts water flow and causes siltation of the channel leading to its closure.

The recent call for the lake entrance to be manually opened by Shoalhaven City Council goes hand-in-hand with the bridge replacement according to Mr Treweeke.

The RTA gave no indication of the time-frame, location, design or cost of the bridge, but did insist that a series of community briefings would be held before any plans are finalised.

If you were to spread the bridge across the lake instead of the causeway you will end up with no defined channel. Everything will slow down and silt up including the existing channel.

This is not the Georges or Shoalhaven Rivers, it's a lake.

Has anyone considered how to get rid of the sandbanks, either side of the causeway?

Even a school child knows that the narrowest part would be faster flowing than spreading it out further.

This is how the lake entrance works when it is open.

One of the reasons that closed was the fact that the water slowed, couldn't form a channel, because of the eroding of the misguided rehabilitated Burrill Sand Spit.

Surely people realise that?

A permanent visitor for 30yrs what an awful sight.

Dont need an expert just ask the fish and the stingrays who desperately want out, a prison for them.

Holiday makers with infections after swimming, everyone commiserates the plight of the lake.

Outdoor anytime without pesticides? forget it.

Your report on mosquito transmission is a crucial concern for residents and visitors who are unaware of the risk.

Mosquitoes are rampant and becoming an increasing threat.

Ochlerotatus vigilax breed in salty pools in mangroves and salt marshes after flooding by heavy rains.

This mosquito will cause Ross River and Barmah Forest virus and dog heart worm.

The disease is not spread from human to human but from animals.

Advice is to clear your home and surrounds of water holding containers.

Do you have kangaroos or small marsupials around you?

Do you live near the lake where it has festered with marshy waters?

Time the council takes notice and clears the entrance for all concerned.

Tidal waters are healthier for all.

Councillors have a responsibility to their rate payers and visitors, regardless where they live.

Yes, hope at last perhaps the RTA and bridge engineers will solve the problem for them.

Hi Alan,

Haven't you heard of the bottle-neck theory, the larger the opening the quicker the lake will discharge and re-enter waters from the ocean.

FYI school children do not learn about the pheonomia of closing and opening of lakes in our education system.

Yes Alan it is a lake and not a cess pool.

We need a new Bridge immediately, not another study.

Sorry Mike, you are wrong.

Having been coming down to the lake since a child in the early 50s and the family having a holiday home on Dolphin Pt since 1960, plenty of people have seen how fast the narrow channel at the entrance has flowed swift and deep as it can go when properly functioning.

It's basic knowledge water moves slowly over a wide area and becomes swifter as it's sides confined, narrows and digs.

This is how the entrance operates.

As a matter of fact, once, I witnessed a man carrying a child step off into the narrowest part at the entrance.

He and the child completely disappeared as we rushed to drag them out. I told didn't he know the narrowest part is the swift, deepest and most dangerous.

No he didn't, he thought it was not so far to cross being the narrowest.

You don't need a study, you just need commonsense.

Hopefully, it's the parents who teach their children such things.
