Victoria Highway – Little Horse and Big Horse Creek Crossings and Road Upgrades



An upgrade of bridges on the Victoria Highway will bring the roadway to a National Highway standard, improve flood immunity and access to the area and improve the road link between the Northern Territory and Western Australia.

The project is located on the Victoria Highway about 300 km west of Katherine near the township of Timber Creek.

As part of the project the existing bridges at Big Horse and Little Horse creeks will be replaced with higher level bridges, raised road approaches and culverts at low points.

The new bridges will be constructed alongside the existing road within the existing road corridor.

Allan King & Sons Construction Pty Ltd was awarded the contract to deliver this project.


Cost - $35.5 million jointly funded by the Australian and Northern Territory governments
Project commencement – July 2017
Estimated completion – June 2019 (weather dependent)

Project scope

The project scope includes;

  • Construction of two bridges and road approaches between chainage 294km to 296.5km at Big and Little Horse creeks which include culverts at low points to the east of the bridges.
  • Safety upgrades to the intersections at the Big Horse Camp ground and the Bradshaw Field Training area.
  • Demolition of the existing bridges.


The Victoria Highway provides the only sealed link between the Northern Territory and Western Australia providing a critical link in the Perth to Darwin National Corridor.

Big Horse and Little Horse creeks are tributaries of the Victoria River and when in flood the highway is closed at both these crossings on average for 96 hours annually.

The project aims to achieve a 1-in-20-year flood immunity consistent with other new crossings on the Victoria Highway; and reduce the Annual Average Time of Closure to less than 12 hours at the crossings.

On completion of works, increased year round accessibility for the pastoral, agricultural and transport industries, tourism and local users on the National Highway will be realised.

This section of the Victoria Highway forms part of the main route to the Bulla and Amanbidji communities, and is utilised by the Bradshaw Defence facility in the vicinity.
