Wollongong City Council needs to "butt out" of next year's planned Lawrence Hargrave Drive closures, said Heathcote MP Lee Evans.
This week, the council passed a motion to write to the government over concerns about Transport for NSW's plan to close the road for two one-month periods next year.
The Heathcote MP is unhappy that council has taken matters into its own hands, given Lawrence Hargrave Drive is a state road.
"Council should butt out of state issues," Mr Evans said.
"If they've got people who have been contacting them instead of me, then send them to me so we can at least capture what people are discussing
"The motion that was put up was how to suck eggs. We're already doing everything, we're already looking into it. We're taking responsibility for what we have to do, we're working our way through it. We're not trying to hurt the community."
Mr Evans classed the council motion as throwing "more petrol on the fire" and harming talks he's about to have with Roads and Transport Minister Andrew Constance.
The closure had been "planned for the last year or two", Mr Evans said, adding it would be taking place now had he not told Transport for NSW to push it back.
However, he and council agreed on one thing - a full closure is not a good outcome.
"I'm going to see Andrew [Constance] next week about it because I'm not happy about it," Mr Evans said.
"Surely in 2019 we can come up with something a bit better than closing a road for two four-week periods.
"Yes it's a difficult site but, lets face it. If we can build a bridge over the ocean at Sea Cliff Bridge we can do a lot more than what we're attempting to do here."
