South Coast Highway Road Safety Improvements

Albany to Jerramungup

This staged project will see the highway widened between Albany and Jerramungup.
South Coast Highway <em>Road Safety Improvements</em>

South Coast Highway is the major west-east inter-regional route and the sole freight and tourism route from the Eastern States to the Great Southern. As a strategic freight route, it carries large amounts of freight to the ports of Albany and Esperance.

This staged program of road safety improvements addresses the potential for road run-off crashes and driver fatigue, caused by the width and geometry of the road.

Mead Road Passing Lane 

We widened the existing pavement from 7 metres to 11 metres from Killarney Road to Monty's Leap Winery, including a 2 metre sealed shoulder in each direction.

A westbound passing lane was constructed between Killarney Road and Monty's Leap Winery, approximately 2.5 kilometres west of Kalgan River Bridge.

Kalgan Overlay and Widening

The existing pavement was widened from 7 metres to 11 metres from Monty's Leap Winery to the Kalgan River Bridge, including a 2 metre sealed shoulder in each direction.


The third section of work currently underway includes the reconstruction and widening of the highway, and construction of two passing lanes between Bluff Creek Road and Kojaneerup West Road.

What’s happening

The third and final stage of works is nearing completion, with the highway now re-opened to traffic. Single lane closures and speed reductions are still in place along sections of the road between Cheynes and Kojaneerup West Road, while finishing works are completed. 

Delays are expected, so use of the previous detours in place are encouraged during this time.
