Mayor Graham told the Lakes Mail this week that the NSW Government expects the council to like or lump it.

"There's not three tiers of government, there's just two, federal and state governments and the NSW Government does whatever it wants with council business like planning and roads. This stretch of road is going to cost us about $200,000 to bring it up to standard and $170,000 a year to maintain and that's money Wyong Shire Council could better spend on other things," Cr Graham said.

"We don't like it and we don't want to lump it. I have written to the Central Coast Minister Ian McDonald, and our member, but so far I haven't had a reply," he said.

The stretch of road from Ourimbah to Tuggerah is now identified as an emergency detour in the event of the F3 Freeway being blocked and Cr Graham says the NSW Government's dumping of that part of the road on council is unacceptable.

"It's nothing more than a clear case of cost shifting assets to the rate payers of Wyong Shire. If councils don't have any say in it, the State Government can palm off onto any council road funding commitments any time it likes.

"This 6.5 kilometres is now the only section of the Pacific Highway from Sydney to Queensland no longer under state control," he said.

Cr Graham said there were only nine councils in NSW with roads reclassified from state to local government.

"All of the others are minor," he said.

An RTA spokesperson said the declassification was negotiated with Wyong Shired Council and agreed in 1995.

"It was offset by reclassifying 6.7 kilometres of Enterprise Drive from local to Regional Road, which happened in 1995," the spokesperson said.

"Wyong Council is entitled to a safety net funding arrangement from the RTA totalling $206,000 over three years."
