The South Coast Highway is a strategic freight and tourism route in the south west region of Western Australia, servicing the ports of Albany and Esperance and connecting regional towns.
However, the age, design and condition of the highway is causing significant safety issues, and high operating and maintenance costs.
Around 74% (or 348 km) of the South Coast Highway consists of pavement that is more than 40 years old. In addition, eight bridges along the highway are timber, with some being almost 60 years old.
Continued decline in road condition, with population growth and increases in freight volumes and tourism activity, will further exacerbate the effects of these problems in the future.
