Great Northern Highway Bow River Bridge and Approaches

Project Description

The Great Northern Highway is the only sealed road between the Port of Broome and the Port of Wyndham on the National Land Transport Network linking Perth with Darwin in the Northern Territory.

The project replaced the low-level single lane Bow River Bridge on the Great Northern Highway with a new 2-lane high-level bridge. The project also included sealing the two lane road to appropriate standards on an improved road alignment, high-level road embankments, rock guide banks at bridge abutments and a new rest area for heavy vehicles.

Benefits

The bridge used to experience regular flooding during the wet season, with the approaches and the bridge width raising safety concerns.

The project has provided:   

• improved road network reliability, through increased flood immunity and reduced road closure duration and incidence
• improved road user safety, through improved road approaches, provision of a two-lane bridge and reduced flooding
• improved road network accessibility between communities and business centres

Funding

The Australian Government provided $18.6 million towards this $23.2 million project.

Timetable

Construction commenced in April 2018 and was completed in November 2018.
