A three-year, staged program of safety improvements, to address road width and geometry issues, has been completed along South Coast Highway.

Mead Road Passing Lane was completed in June 2019 and included construction of a westbound passing lane between Killarney Road and Monty’s Leap Winery, along with widening works and a two metre sealed shoulder in each direction.

Work on the Kalgan section, which included widening the existing pavement from seven metres to 11 metres from Monty’s Leap Winery to the Kalgan River Bridge, was completed in April 2020.

The third and final stage of this safety improvement program included reconstruction and widening of the highway, and construction of two passing lanes between Bluff Creek and Kojaneerup West Road.

This project provides safer travelling opportunities for commuters and improved transport efficiencies.


  • A wider, safer road with improved sight lines
  • Additional passing opportunities
  • Potentially reduced travel times
  • Sealed shoulders
