Shoalhaven City Council is advising local residents the closure of Bolong Road, between Meroo Street and Railway Street, Bomaderry will be in place until 7.30pm Thursday.

The closure comes after Shoalhaven Water staff struck a gas main while searching for a broken water main on Bolong Road.

While it was initially thought that the main could be fixed quickly, it has since become apparent that the broken line is the main feed to the Manildra Plant.

As such, it is expected that Bolong Road will be closed between Meroo Street and Railway Street until 7.30pm .
