Project description

This project involves the construction of a new interchange between the M1 Princes Motorway and Mount Ousley Road. The interchange will replace the existing intersection, which is a significant pinch point of the Motorway network, and currently experiences long queues and delays during peak periods. As the primary access point to Wollongong and Port Kembla, issues at this intersection also create significant flow-on effects across the wider transport network. This project will improve travel times, as well as access to the Wollongong central business district and the University of Wollongong. It will ensure safer access to and from the Motorway to Mount Ousley Road, and improve safety by separating cars and heavy vehicles travelling down Mount Ousley.

Benefits

Improved road safety for all road users Reduced congestion and improved travel times Improved efficiency and network reliability

Funding

The Australian Government has committed $312 million to this project.

Timetable

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.
