Port Macquarie-Hastings Council has asked the community to be aware of changed traffic conditions, and to seek alternate routes, as a result of the road reconstruction works in Gordon Street.
The busy arterial route carries more than 21,000 vehicles a day.
Traffic congestion and increased travel times are being experienced, particularly during peak periods.
The section of Gordon Street between Horton Street and Lake Road is now single lane in each direction, and changes have been made to the Horton Street, Hay Street and Lake Road intersections to allow for works to the road itself and underground services.
Electronic sign boards advise of the changes and traffic management measures are in place to ensure the safety of the community and work crews as part of NSW road safety regulations.
Motorists are being asked to follow all directional signs and seek alternate routes where possible.
Night works will also occur at certain times to minimise disruption to the community.
The upgrade includes widening of the existing road pavement, installation of kerb and guttering, pedestrian footpaths, street lighting and a central median.
These works all contribute to increased safety for vehicles and pedestrians, and improve pedestrian access.
New asphalt pavement will also ensure improved ride quality.
In addition, new pavement works will be undertaken at the Hay Street intersection with existing electricity, water and reclaimed water services to be relocated.
New stormwater lines are being installed to improve drainage.
Works started in late May and are expected to be completed by September, subject to favourable weather and ground conditions.
The council thanks residents, businesses and the broader community for their cooperation and patience while these important works are undertaken.
