Project description

The road requires full pavement reconstruction due to its narrow width, failed pavement and seal, and inadequate drainage affecting both the road and shoulders. As a critical freight route for the area, the existing surface has deteriorated under heavy vehicle use, compounded by insufficient pavement depth and poor stormwater management. Located within an 80 km/h zone, the road experiences significant interaction between heavy and commuter vehicles. Widening the road and shoulders will address these issues and significantly improve safety for all users.

This project involves the reconstruction of 1.15 km of Supple Road with a new granular pavement and a 40mm asphalt surface, designed to accommodate increased heavy vehicle loading. The upgrade includes widened sealed and unsealed shoulders, improved stormwater capacity, and enhanced drainage. The existing road, which has reached the end of its service life, will see its overall carriageway width expanded from 6 metres to 9.4 metres, while the pavement depth will increase from a variable 200–300mm to a consistent 380mm, ensuring greater durability and performance. Council/s contribution: $965,000.00

Total cost of proposed project is $1,930,000

The Gardens Road (Alice Springs Rural Road) - 059887-15NT-RTR

The Gardens Road services the pastoral, tourism, mining and indigenous community industries. The nearby Alice Springs to Darwin road rail crossing is currently being upgraded to 2 lane 7m wide seal, finishing at the existing narrow non-standard, single lane grid. The upgrade of the grid and drainage is a safety issue.It is proposed to raise the grid to allow drainage to occur, widen the grid to standard 9.6 metre width, raise the road approaches and build fence on both sides of the grid for traffic safety.
