What is happening
Roadwork to reconstruct a 13.8 km section of the Southern Ports Highway from the Southend Access Road Junction to the Beachport outlet.
The project will be completed under an investment from the joint Federal and State Government’s $168 million Road Safety Program. The roadworks are being undertaken by Wattle Range Council on behalf of the Department for Infrastructure and Transport (DIT).
How the roadworks and road closures will affect you
The reconstruction will be completed in stages including periods of full road closures with detours in place. This allows the work to be carried out efficiently while ensuring manageable disruptions to residents and businesses.
Council understands the road closures will cause a temporary inconvenience; however, it’s a necessary step to ensure the reconstruction of the road is delivered to a high standard, in a cost-effective manner, and within a reasonable timeframe. To minimise disruption, roadworks will pause during the summer school holidays.
Local residents and businesses who regularly travel between Southend and Beachport may be eligible for a permit to allow direct access under restricted conditions.
