Something that is proving frustrating for residents in and around Mark Radium Park, Windsor Drive, North Street and parts of The Arbour and Huntingdale Park, who have complained about the noise from the $580 million bypass from not long after it was officially opened to traffic on July 13, 2017.

The residents say the bypass on the south western side of the township has turned their lives into a "living hell".

Residents took up their case with Kiama MP Gareth Ward, Roads and Maritime Services and even wrote an open letter to NSW Premier Gladys Berejiklian.

In December last year they believed they had received an early Christmas present with the news $5.3 million had been allocated to construct noise mitigation measures, which Mr Ward described as a "major outcome for residents".

At the time Mr Ward said the RMS would release concept designs for the project and would consult with the community prior to going out to tender for work in the first half of 2019.

Resident and wall campaigner Tina Ballard said little or no work appears to have been done on the project.

"One could not be condemned in assuming that, despite allocation of monies, ratified by NSW Treasury and confirmed by Mr Ward for construction of noise reduction walls, little of no work has been done," Ms Ballard said.

"It appears there is no importance or urgency attributed to this work. Rather, one is forced to deduce the project is not being taken seriously by those charged with the task.

"We were told there would be community consultation in the first quarter of 2019 and construction in the second quarter of 2019.

"However, communication with RMS has revealed no decision or plans regarding construction of walls has been done and 'work was being done in the background'.

"We are now being told the RMS plans to consult with affected residents about their individual experiences with the noise.

"Apparently, the RMS plans to set up individual 'sound studios' at each residence for 24 hours each to 'monitor' individual experiences of noise.

"This will allow them to work out what kind of walls to construct. Will they then turn around and say that there is no need for walls?"

Ms Ballard said Mr Ward's Facebook page stated work would begin in the second quarter of 2019.

"So, will work now drag on until Christmas?"

"We have been assured it won't

"Everyone knows what the problem is. It just seems like groundhog day.

"We have been through sound monitoring at Easter 2018; the report was not released until year's end; here we are and Easter has come and gone again and we are having the same conversation about noise monitoring.

"We are no longer frustrated. We have reached the stage that we expect this kind of treatment."

Roads and Maritime Services has confirmed they will carry out planning and investigations to install noise walls.

"The walls will be installed near Huntingdale Park Estate and Windsor Drive, Berry," the statement said.

"We will be speaking to residents adjacent to the proposed walls in the near future about their current noise experiences and we will keep the community updated as this project progresses."
