Transport for NSW (TfNSW) said essential maintenance works are expected to take five months to complete, weather and site conditions permitting.
These works will take place south of Maclean, between Shark Creek and Lees Drain.
For the first six weeks a contraflow traffic arrangement will be in place, running 24/7, with a reduced speed limit of 80km/h. The remaining three months of work will have a single lane closure with a speed reduction of 60km/h.
Oversize and overmass (OSOM) vehicles more than 3.5 metres wide intending to travel through the work sites will have to call the project team on 0409 293 187 at least 24 hours prior to travel.
