The roadwork, between Oyster Cove Road and Avenue of the Allies at Tanilba Bay, will be funded by the NSW Government's Saving Lives on Country Roads Program and involves shoulder widening, superelevation to make the corner easier to navigate and installing a wire rope barrier to improve safety for drivers.

Construction is expected to take 12 weeks to complete, weather permitting.

The council's capital works section manager Phil Miles said that it was a much-needed improvement for the Tilligerry Peninsula.

"This is a notorious stretch of road that has unfortunately been the site of five major crashes in as many years. This upgrade will ensure this corner is easier to navigate and safer for motorists," he said.

"These works are the first of several improvements to Lemon Tree Passage Road that are scheduled for this financial year. Other scheduled works include improvements to the section near Rookes Road opposite the tennis courts, as well as an upgrade to the roundabout on Nelson Bay Road on behalf of Roads and Maritime Services."

Work will take place Monday to Friday from 6am to 6pm and Saturdays from 7am to 2pm. To ensure the safety of motorists and workers, one lane will be closed and a 40km/h speed limit will be imposed during work hours.

"We appreciate that Lemon Tree Passage Road is an important thoroughfare for locals and visitors, so we will be doing all we can to work closely with the residents to manage the inconvenience.

"I'd ask people to be patient with the work crews, follow the directions of traffic control and allow extra travel time so they can get where they need to be," he said.
