Trewilga - Newell Highway realignment

The NSW Government has funded $36 million to address safety concerns for this section of the highway.

Roads and Maritime Services has upgraded and realigned 6.5 kilometres of the Newell Highway north of Parkes. The work extends from 36.7 to 43.1 kilometres north of Parkes.

Updates and announcements

Trewilga – Newell Highway

The Trewilga Newell Highway realignment project officially opened to traffic on Friday 9 February 2018.

Roads, Maritime and Freight Minister Melinda Pavey officially opened the upgraded Newell Highway at Trewilga, on time and on budget.

Mrs Pavey said work on the $36 million upgrade and realignment started in July 2016 to improve road user safety and address the high casualty crash rate along this busy section of the highway.

“The NSW Government is committed to reducing the number of accidents on our roads and this project is another piece of the puzzle which will benefit motorists and the community for years to come.

Minister Pavey said the local workforce also got involved with the project with around 80 per cent of the workers living locally or within the region.

“This project generated considerable local employment and jobs ranging from traffic control to crane operation and concreting.

“The aim is always to create as much local employment as possible with projects on state roads and the safety upgrade and realignment at Trewilga has done just that.

Project background

The Newell Highway extends from the Victorian border to the Queensland border and is an important link for freight movements. Heavy vehicles make up about 31 per cent of traffic along this section of the highway with the majority being 26 metre B-doubles. The volume of heavy vehicle traffic is expected to increase annually.

The majority of the Newell Highway has a posted speed limit of 110 km/h. The section of the highway at Trewilga was posted at 100 km/h and the upgrade has bought this section up to 110 km/h.

Project objectives

The project has improved the safety of the highway for road users and addressed the high casualty crash rate along this section. It has also upgraded the 'missing link' along the Newell by raising the speed limit from 100 km/h to 110 km/h as Trewilga was the only rural section of road between Forbes and Gilgandra that had a speed limit of 100 km/h.

Key features

  • A new alignment for about 3.2 kilometres
  • Widening of the current highway to allow a 1.2 metre wide centreline and increase the width of sealed shoulders
  • A bus turning area at Baldry Peak Hill Road
  • A northbound 1.3 kilometre overtaking lane
  • Truck parking areas on the eastern side of the highway.

Community engagement

The community has participated in a two-way exchange of information with Roads and Maritime Services about the Trewilga realignment project.

How has the community been kept informed?

Roads and Maritime staff had one-on-one meetings with affected residents and held staffed displays at the Peak Hill Services Club in May 2012 and Peak Hill Community hall in November 2016.

What types of issues has the community been consulted on?

The community has discussed many issues, including:

  • The protection of the Trewilga Cemetery
  • Access for local school bus routes during and after construction
  • Local and access roads
  • Property acquisitions
  • Impacts on the rail corridor
  • Noise and vibration levels during construction.
