Motorists are advised of changed overnight traffic conditions on the Pacific Motorway at the Tugun Bypass Tunnel from this Friday, as Traffic NSW carries out maintenance work.

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

To reduce the impacts on motorists, work will be carried out over five nights. The tunnel will be closed to all traffic from 8pm to 6am AEDT each night from Sunday 20 February. Work is expected to be complete by 6am AEDT Friday 25 February, weather permitting.

On the night of Monday 21 February, northbound and southbound traffic will detour via the Kennedy Drive interchange. Southbound traffic will re-enter the highway at the Kennedy Drive on-ramp.

On all other nights, traffic will be diverted at the Gold Coast Highway interchange. Northbound and southbound traffic will be diverted onto the Gold Coast Highway and Stewart Road during the closure.

The tunnel will remain fully operational during the day.

Motorists are advised to drive to the conditions, allow up to 10 minutes additional travel time, and follow the directions of signs and traffic control.

Transport for NSW thanks motorists for their patience while this essential maintenance work is carried out.
