Cobb Hwy & Silver City Hwy upgrade program

What does the project mean for the local and wider network?

• Fewer highway closures – As part of the road upgrade, table drains will be established on both sides of the highways to remove water from the road during periods of heavy rainfall.
• Greater economic opportunities for local and interstate businesses - The upgrade will provide a more secure transport route for local produce and industries.
• More efficient travel – A sealed road will mean motorists have a smoother journey, better visibility of the road and a more direct route across western NSW.
• Safer travel conditions - Gravel roads can be difficult for motorists to travel on due to their roughness and the amount of dust generated by vehicles. Sealing the highways leads to improvements in road safety.

Other benefits for locals and the wider community include:

• More reliable access to schools and hospitals
• Reduced travel times by up to 30 minutes
• Improved connections for the freight and livestock industry in remote NSW
• Reduced time, cost and resources used in road maintenance
• Improved wet weather immunity and more reliable road access
• Smother and safer road surface.

The key features of the sealing and upgrade work include:

• Constructing north and southbound traffic lanes
• Rebuilding and sealing the roads
• Installing drainage structures to combat impacts of flooding
• A new bridge at Packsaddle Creek, completed in April 2019
• Installation a landing strip for the Royal Flying Doctor Service at Shannon’s Creek, completed in 2015.
