Newell Highway upgrade Mungle Back Creek to Boggabilla

The Australian and NSW governments have committed funding to upgrade the Newell Highway between Mungle Back Creek and Boggabilla in Northern NSW. This will improve safety for motorists and reduce future maintenance requirements. The project includes major work on 18 kilometres of new road pavement, 3.5 metre wide lanes in each direction, intersection improvements, widening of road shoulders and provision of two new overtaking lanes.

NOV 2018Traffic switched to new section

Work started in November 2018 and is progressing well with traffic being switched onto a new 1.3 kilometre section of highway. The milestone includes an upgrade to the largest intersection on the project, where the road has been widened to accommodate large trucks and a new dedicated turning lane, travelling south into Letterbox Road complete.

The upgrade will also include a one metre wide centre line to allow more room between vehicles, and improve safety along this important section of road, which is known for being narrow and uneven.

The project will take around three years to complete. During construction speed will be restricted to 40km/h, 60km/h and 80km/h at different times. Please allow extra travel time and follow the direction of traffic controllers and signs. Work will take place from Monday to Friday between 7am and 6pm.

Roads and Maritime Services thanks motorists for their patience during this important upgrade work.

Roads and Maritime awarded the construction contract for this major project to Fulton Hogan Construction Pty Ltd, in August 2018.
