The M1 Pacific Motorway extension to Raymond Terrace: Heatherbrae Bypass forms an integral part of the M1 Pacific Motorway and the A1 Pacific Highway which runs between Sydney and Brisbane, and as such is a critical part of the freight and movement network of New South Wales (NSW). The works represent the final bypass stages of the M1 Pacific Motorway which will result in reduced congestion and conflict with local traffic movements.

The Project is:

  • Located 23 kilometres north of Newcastle in the City of Newcastle and Port Stephens Council LGAs.

  • Located in close proximity to the Mid North Coast and the coastal regions of Newcastle and Port Stephens.

  • A predominantly rural urban area that plays an important role in NSW regional economy.

  • Comprises important land uses include manufacturing and industrial areas.

  • Located to the east of Heatherbrae skirting the perimeter of its development.

Elements of the Project include:

  • A five-kilometre motorway upgrade connecting the southern section of the M1 Pacific Motorway extension to Raymond Terrace.

  • One interchange at Raymond Terrace.

  • Three bridges including two overbridges and one creek bridge over Windeyers Creek.

The design has been developed to achieve the Project objectives and principles as outlined in the approved Planning documents. The key initiatives include:

  1. The reinstatement of the enclosed forest to the east of the alignment.

  2. Provision of screening landscape to the west to reduce the visual impact of the Motorway from the community of Heatherbrae.

  3. Feature landscape at the northern interchange at Raymond Terrace which provides a distinct character that separates from the adjoining forest communities whilst responding to the Windeyers Creek creekline landscape, which is in close proximity to the interchange.

  4. Incorporation of fauna crossings.

  5. Incorporation of interpretive elements, developed with Aboriginal artist Saretta Fielding of Saretta Art & Design on the safety screens and in the interchange. The safety screens incorporate visual motifs of objects and symbols of cultural themes identified by Saretta that respond to Country.
