Highway tunnel will close this week

MOTORISTS are advised of changed traffic conditions this week on the Pacific Highway at the St Helena Tunnel for essential maintenance work to be carried out.

The north and southbound lanes of the tunnel will be closed between 7pm and 6am on Wednesday and Thursday.

Northbound and southbound traffic will be diverted onto the Hinterland Way, between the Byron Road interchange at Bangalow and the Ewingsdale Road interchange at Ewingsdale.

Motorists are advised to allow an additional five to ten minutes travel time for the diversion.

Routine maintenance of the St Helena Tunnel is carried out every three months and involves a range of measures, including inspecting the various operating and safety systems.

Roads and Maritime Services thanks the community for its patience while this essential maintenance work is carried out.
