Work to build an additional southbound onload lane to the Princes Highway roundabout at Bulli will continue next week.

Work will be carried out at night on Sunday 21 and Monday 22 August, between 7pm and 4am, weather permitting.

Temporary concrete barriers have been installed on Memorial Drive along the righthand shoulder from the roundabout to the pedestrian over bridge. Southbound traffic will be directed onto the road shoulder during work.

During night work the southbound onramp to Memorial Drive will be closed and detours will be in place via the Princes Highway through Woonona and Bellambi Lane.

A reduced speed limit of 40 km/h will be in place during work and road users are advised to allow five minutes additional travel time, drive to the conditions, and follow the directions of signs and traffic control.

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