Member for Port Macquarie, Leslie Williams said the installation of traffic lights on one leg of the roundabout and slip lanes in and out of Wrights Road would improve traffic flow and reduce congestion during peak times.

"Work is scheduled to start on Tuesday and will involve installing traffic lights at the eastbound entry lane from the Oxley Highway onto the roundabout," Mrs Williams said. "Modelling shows traffic signals at this location will ease congestion on the approaches to the roundabout, while providing easier access for vehicles wanting to access Wrights Road and John Oxley Drive.

"Additionally, slip lanes from the Oxley Highway into Wrights Road and from Wrights Road into John Oxley Drive will be built to help ease traffic congestion in the area," Mrs Williams said.

"A range of activities will be carried out during the project, including underground boring for the traffic light installation, relocating street lighting, earthwork, vegetation clearing, construction of the slip lanes, drainage work and line marking.

"The project is expected to take about six months to complete, weather permitting. Access to the Port Macquarie Base Hospital will be maintained at all times during construction.

"Nearby residents and businesses will be kept informed of the project's progress and any potential impacts well in advance," Mrs Williams said.

Work will be carried out Monday to Friday, 7am to 6pm and Saturday 8am to 1pm, weather permitting.

Motorists are asked to follow the direction of traffic controllers, keep to the speed limits and follow traffic signs and lights when displayed.
