The Keep River Plains Road is located approximately 55kms outside of Kununurra on the NT/WA Border.
Under the leadership of Greg Rhodes, Exact proudly constructed a new 26.7 km roadway and two new bridges, including the longest bridge in the Northern Territory being the Keep River Bridge of 210m:
Stage 1 Works – from Chainage 0.0km to chainage 13.475km including a 210m long bridge over Keep River; Stage 2 Works from Chainage 13.475km to chainage 26.7km including a 69m long bridge over Sandy Creek.
The project aimed to provide the following benefits:
- Increased route accessibility to support the planned Project Sea Dragon and Ord Stage 3 developments
- Improved freight capacity, through sealing of existing pavements
- Improved flood immunity, through provision of new bridges over the Keep River and Sandy Creek
- Increased regional productivity and economic development, through provision of year-round road access.
The Works included:
- Approxmately 600,000BCMs of Earthworks including the pushing and screening and blending of specified fill materials.
- Pavements including the pushing and screening and blending of specified pavement materials.
- Lime Stabilisation of the embankment foundation and cement stabilisation of the pavement layers.
- Spray sealing, pavement marking, road furniture, traffic control devices and fencing.
