Mr Gay said the cost difference between a bypass to the north and a bypass to the south of Berry was more than $100 million.

“The substantial savings for the northern option makes it the clear choice,” Mr Gay said.

Roads and Maritime Services (RMS) announced a revised northern alignment for the Berry bypass in December last year.

‘‘However it became clear in February that a detailed cost evaluation of a southern Berry bypass route was also warranted,’’ Mr Gay said.

‘‘A community submission about a southern route suggestion outlined proposed cost savings as well as other benefits including not dividing Berry.

‘‘I asked RMS to rigorously examine the suggested southern route and a technical investigation group was established.’’

Kiama MP Gareth Ward said there has been considerable discussion in the community about the options and it was important they were thoroughly examined.

“Now that a decision has been made, it is time to get on with the job of delivering the upgrades that will deliver major safety and time benefits for motorists and the broader community,” Mr Ward said.

"Whilst I appreciate the views of those who wanted a southern bypass, the cost differential of $100 million is cost prohibitive.

‘‘I believe that people would rather see the bypass built than lose this opportunity to get the job done.

‘‘The important thing now is for the town to unite so we don’t lose potential funds to the Pacific Hwy.

‘‘I am absolutely intent on delivering the project which others have only ever talked about since 1955.’’
