Transport for NSW advises motorists of changed overnight traffic conditions next week on the Pacific Motorway to carry out a control system upgrade at the St Helena Tunnel.
The north and southbound lanes of the tunnel will be closed on from 7pm to 5am on the nights of Monday 19 to Wednesday 21 June, reopening at 5am on Thursday 22 June, weather permitting.
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 up to 10 minutes additional travel time for the diversions, drive to the conditions and follow the direction of signs and traffic control.
This work is part of the control system upgrade and involves a range of activities, including testing the tunnel’s traffic and safety systems.
Transport for NSW thanks motorists for their patience during this time.
