A project to upgrade the intersection of Taren Point Road and The Boulevarde at Caringbah will start in February and could take up to eight months to complete.
The intersection will be widened to provide an extra right-turn lane for southbound traffic heading west.
Work will involve realigning the north-west corner, next to Endeavour Sports High School, widening pedestrian crossings, new signals and footpath and fencing replacement.
Roads and Maritime Services (RMS) expects the upgrade, which former Premier Mike Baird promised before the 2015 state election, will provide a faster flow for both westbound and southbound traffic.
The project comes five years after the single right turn lane into The Boulevarde was extended by 40 metres.
State MPs Mark Speakman and Eleni Petinos said in a statement work was expected to start on February 1 and take up to eight months to complete.
“About 70,000 vehicles travel through this intersection daily, with southbound motorists on Taren Point Road experiencing significant delays when trying to turn right into The Boulevarde,” Mr Speakman said.
“This project will...help deliver faster journeys for road users heading towards Miranda, Gymea, Kirrawee, Sutherland and beyond,” he said.
Ms Petinos said more than 1600 students attended Endeavour Sports and Caringbah High schools, “making the intersection a major hub for pedestrians, particularly during morning and afternoon pick-up and drop-off times”.
“The upgrade includes relocating and widening the pedestrian crossings on The Boulevarde, and replacing the footpath and fencing along the north-west corner of the intersection,” she said.
“New pedestrian crossing lights will be installed and the intersection will be resurfaced with new line markings, including on each of the four pedestrian crossings, to make it safer and easier for people to cross the road.”
Ms Petinos said RMS was working closely with the schools to ensure students, parents and teachers were kept informed as the work progressed and as little disruption as possible occurred.
Work will be carried out on weekdays between 7am and 6pm, and between 8am and 1pm on Saturday.
Work may also take place on up to five nights a week between 8pm and 5am from Sunday to Thursday, weather permitting and excluding public holidays.
