Traffic will be reduced to a single lane for a month for heavy patching work on the Newell Highway north of Parkes.
The work will begin from Monday, 3 March.
Transport for NSW workers will carry out the job between one kilometre from the Parkes Bypass and Tarcoma Road on weekdays between 7am and 5pm until Friday, 28 March, weather permitting.
Single lane closures and a reduced speed of 40km/h will be in place during work hours for the safety of workers and road users. The speed limit will return to 60km/h outside of work hours.
Transport for NSW said road users should follow the directions of traffic control and signs, and allow up to five minutes of additional travel time.
