Ongoing community concerns have prompted authorities to review the safety of a wet and slippery mountain pass between the Pacific and New England highways.

Inspectors from the NSW Roads and Maritime Service (RMS) will look at all aspects of the Waterfall Way, between Dorrigo and Raleigh on the NSW central coast.

Locals say a massive increase in truck traffic has enhanced the risk on Waterfall Way, as hundreds of gravel-hauling quarry trucks are channelled onto the state highway due to the Pacific Highway upgrade.

Representatives from the community group ‘People with an Interest in Road Safety for the Waterfall Way’ say their concerns are not with the conduct of the truck drivers, but with the state and durability of the road itself.

RMS Regional Manager John Alexander has told the ABC that while community input will be part of the review, suggestions for an entirely new bypass are unlikely to go through.

“A bypass is a very different proposition, in that it takes a long time to work through, there's a very long planning process,” Mr Alexander said.

“There's lots of issues about environment, property and other factors including cost.

“It's just not on the radar for us at the moment.”

The authority says there are plenty of cheaper options to ease the strain on Waterfall Way.

“It could be pull-off bays, shoulder work or pavement improvement,” he said.

“There could be behavioural things, some messages to the community.

“We're hoping to work with the company to maybe get some protocols about the way they drive through Bellingen.

“It could be a mixture of all those sorts of things, things that can be done in the short-to-medium term.”
