Gwydir Highway


Project overview

The Gwydir Highway provides a vital link between the east coast of New South Wales and the New England tablelands and western plains.

Project information


The Gwydir Highway stretches 567 kilometres, starting in the northern rivers of NSW at South Grafton and extending west to 14 kilometres north of Walgett.

The highway provides an important east-west freight link across the Great Dividing Range and connects a series of interstate highways and important interregional corridors with inland urban centres.

The Gwydir Highway intersects with:

  • The Pacific Highway and Summerland Way at South Grafton,
  • The New England Highway at Glen Innes,
  • Fossickers Way at Warialda,
  • The Newell Highway at Moree
  • The Castlereagh Highway near Walgett.

Traffic volumes along the Gwydir Highway show peaks in the major regional centres of South Grafton, Glen Innes, Inverell and Moree and level off in rural areas and towns along the corridor.
