Changed traffic conditions continue next week on the Pacific Highway to progress the Woolgoolga to Ballina upgrade. A planned traffic switch on the Pacific Highway at Maclean has been postponed to Monday 30 July. From Monday, traffic will be moved onto a new diversion road on the Pacific Highway north of Jubilee Street, Maclean. This arrangement is temporary and will be in place for about 10 months. The access road between the Pacific Highway and Morpeth Street, Harwood will be closed for up to five weeks from Monday 30 July. During this temporary closure, there will be a detour in place via Watts Lane. The road closure is part of work to build the new Harwood interchange and involves two nights of work to install traffic barriers. Motorists can expect reduced speed limits and lane closures. Five nights of work will be carried out on the Pacific Highway at Chatsworth and Jacky Bulbin Flats from Monday to install traffic barriers. There will be lane closures and motorists should follow the direction of traffic control. Four nights of work will be carried out on the Pacific Highway at Devils Pulpit from Monday.

Two nights of work will be carried out on the Pacific Highway between Coolgardie Road, Coolgardie and Whytes Lane, Pimlico from Tuesday 31 July.  Work will involve line marking at four new access gates for construction vehicles. Motorists can expect a temporary lane closure and should follow the direction of traffic controllers. Additional changes to local roads Work will start from Monday on connecting the Avenue Road overpass with the permanent road, including new intersections with Wants Lane and Old Six Mile Lane in both directions at Glenugie. The speed limit will be reduced to 40km/h and traffic control will be in place while this work is completed. Controlled blasting will be carried out at the Gibsons borrow site, Bagotville on Tuesday 31 July.
