Central Coast Council has started a $1.7million project to install new drainage crossings underneath The Ridgeway, Stage 2 of a $7.8million upgrade of the road.

The current project includes the installation of five drainage crossings, new kerb and gutter and new road pavement.

In order to install the new drainage, Council will need to close The Ridgeway at night between Nexus Way and Tapley Road, Lisarow to all non-resident traffic from Monday 1 October to Thursday 11 October, weather permitting.

A detour will be available via Fagans Road and work will take place between 6pm to 3am to minimise impact on traffic.

Traffic control will be in place to ensure the safety of motorists, cyclists and pedestrians.

Residents who live along this section of road and emergency vehicles will have access at all times and will be guided by traffic control.

Council thanks the community for their patience during these important works and apologises for any inconvenience.

The current project follows on from Stage 1 which included similar road and drainage upgrades and construction of a large sandstone wall.
