Motorists are advised of changed traffic conditions next week on the Pacific Highway between Mororo and Devils Pulpit as part of the Woolgoolga to Ballina upgrade.

From Monday 6 April motorists will be permanently moved onto 10 kilometres of dual carriageway, one lane in each direction, between Mororo and Devils Pulpit.

There will be up to two nights of work to complete this traffic change.

As part of this change, Mororo Road and Jacky Bulbin Road will become left-in, left-out only at the Pacific Highway and U-turn bays will be provided to allow motorists to travel south.

Until the new southbound rest area at Mororo is built, northbound and southbound motorists will continue to access the existing Bundjalung rest area.

Motorists are advised to drive to the conditions, and follow the directions of signs and traffic control.

Reduced speed limits will be in place while work is carried out.

Transport for NSW thanks road users for their patience during this time.
