There will be changed overnight traffic conditions until January 29 as road maintenance work continues on Wyong Rd at the Bryant Dr roundabout at Tuggerah.
Transport for NSW is carrying out the work, which involves cutting grooves into the road surface to improve skid resistance at the roundabout.
Work will be carried out from Wednesday, January 17, to Monday, January 29, over six shifts.
To minimise impact to motorists, it will be carried out from 7.30pm to 5am from Sunday to Thursday, weather permitting.
Single lane closures, traffic control and a 40km/h speed limit will be in place during work hours for the safety of workers and motorists.
Motorists are advised to drive to the conditions and follow the directions of signs and traffic control.
