Traffic diversions are in place, with one north bound lane shut down on Central Coast Highway in front of the Caltex complex opposite Erina High School, while council crews work to investigate the cause of damage to a water main in the area.

Access into both the Red Rooster and Caltex complex opposite Ernest Street is restricted from both directions.

The diversions are expected to be in place until 11pm tonight, with more lanes potentially affected as investigations continue.

Council is appealing to motorists to avoid the area if possible.

Nearby properties may experience intermittent water supply for the duration of the works.
