Motorists are advised of changed traffic conditions from next week on the Pacific Motorway at Pillar Valley to carry out repair work on the northbound lanes at the site of a serious truck crash.

From Monday 20 September, all traffic will be directed onto the southbound carriageway with one lane in each direction at all times while work is carried out to remove and replace damaged road surface, repair roadside and bridge barriers, replace bridge joints and environmental repair.

Work will be carried out from 7am to 6pm on weekdays and 8am to 1pm on Saturdays, and is expected to be complete in three months, weather permitting.  

Traffic control and a reduced speed limit will be in place for the safety of workers and motorists.

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

Transport for NSW thanks motorists for their patience during this time.
