Roads and Maritime Services will carry out the work from Monday, May 12 between 7am and 6pm for about two weeks, weather permitting.

Mr Constance said the upgrade would be funded by the NSW Government black spot program, and would be completed in conjunction with routine maintenance work.

"The road shoulders will be widened to provide motorists with a safer area to recover if they lose control and run off the road," Mr Constance said.

“Later in the year, further work to improve safety will be carried out to install clearer signs for motorists and reseal the road with a more skid resistant surface.

"These improvements are expected to reduce wet weather crashes, with 22 of the 24 crashes in this area in the past five years occurring in wet conditions.

“The road safety improvements are part of Roads and Maritime’s commitment to deliver safe, efficient and high quality services and infrastructure to the community and businesses of NSW."

The new state treasurer also said safety has been improved for motorists entering Jigamy Farm from the Princes Highway south of Eden, with Roads and Maritime Services widening the road around the entry.

“The NSW Government allocated $1.3 million to widen the Princes Highway to provide safer access in and out of Jigamy Farm, and improve safety for motorists travelling on the Princes Highway," Mr Constance said.

“A new guard rail was also installed to reduce the risk and severity of crashes involving vehicles leaving the road.

"Minor finishing work including the final seal and line marking will be carried out in September.

"Carrying out this work at a warmer time of year will ensure the seal provides a safer road surface to serve the community well into the future."

The RMS thanks motorists for their patience while these important upgrades are carried out.
