Kwinana Freeway Widening

Leach Highway to Roe Highway

 

Overview

The project to widen Kwinana Freeway to three lanes in each direction between Leach and Roe Highways has been completed. The majority of the final works were undertaken during April/ May 2013 and remaining works involving landscaping, including planting and seeding, was completed September 2013.

The $58 million project was funded by the State and Commonwealth Governments.

The project involved:

  • widening and upgrading around 4.5 km of Kwinana Freeway between Leach and Roe Highways;
  • construction of a new intersection at South Street and the newly constructed Fiona Wood Road;
  • construction of noise walls for traffic noise mitigation and screen walls to maintain residential amenity;
  • resurfacing the Freeway and ramps within the works; and
  • associated works such as drainage, lighting, service relocations, signage and pavement marking; and revegetation and landscaping works.

 

Benefits

Project benefits included:

  • improved freeway capacity over this section;
  • reduced congestion and travel time;
  • improved safety for motorists; and
  • improved transport efficiency to the port of Fremantle.

Background

Kwinana Freeway is a major freeway extending south from the Perth CBD. With the Mitchell Freeway north of the city, it forms the major north-south spine for road transport in the Perth Metropolitan area.

Current traffic modeling on this section of the freeway shows that the existing two lanes in both directions between Leach Highway and Roe Highway on Kwinana Freeway do not provide enough capacity for freeway traffic. This will increasingly impact on freight transport efficiency and reliability to the Port of Fremantle, as well as adversely affect road safety, fuel consumption and greenhouse gas emissions.

The Mandurah railway has provided commuters with a transport alternative, but road traffic will keep growing on this link due to:

  • urban expansion in the South West Corridor;
  • the Freeway extension to Mandurah;
  • the connection to Bunbury via the Forrest Highway;
  • extra demands expected in this area from the Fiona Stanley Hospital, which is currently under construction; and
  • the Leach Highway freight transport prohibition, which means that freight vehicles access the Port of Fremantle muse use Kwinana Freeway between Leach Highway and Roe Highway.
