Western Port Highway, Lynbrook to Langwarrin

We’ve improved safety along the Western Port Highway, between the South Gippsland Highway interchange in Lynbrook and the roundabout at North Road in Langwarrin, to reduce road trauma and save lives.

What we've done

Flexible safety barriers were already in place along sections of the road. 

As part of this project we’ve installed additional flexible safety barriers on the left-hand side and centre median in high-risk locations, to provide a continuous safer corridor to reduce the risk of head-on and run-off-road crashes.

Infrastructure plays a vital role in preventing serious crashes. It also helps reduce the severity of crashes when they’re unavoidable.

Road safety infrastructure such as flexible safety barriers, wide centreline treatments and rumble strips help prevent the most common crash types, head-on and run-off-road collisions, which in 2015 were responsible for 40% of Victoria’s road deaths and serious injuries. 

Mistakes happen, which as humans we can’t always avoid. What we can do is build more forgiving road infrastructure so that when a mistake does happen on the road, it doesn’t cost a life.

The Western Port Highway is an important route linking Melbourne to growing communities in South-Eastern suburbs and the Western Port Bay. The highway is a key freight route and gateway to significant industrial and commercial precincts.  Improving safety along this corridor is important to supporting the growing economies and communities in the region.  

Between 2012 and 2017, there were nine people who suffered serious injuries along this stretch of road. 

We’re improving safety along the Western Port Highway, to build a future where no one is seriously injured or killed on our roads. 

Works were completed on this project in July 2020.
