  • Kwinana Freeway southbound and Roe Highway westbound congestion set to improve
  • Lend Lease Engineering wins contract to undertake Kwinana Freeway Southbound Widening project

The Australian and Western Australian governments are getting on with delivering world class infrastructure for Perth today announcing that Lend Lease Engineering has been awarded the contract to undertake the Kwinana Freeway Southbound Widening Project.

The Assistant Minister for Infrastructure and Regional Development Jamie Briggs and Western Australian Transport Minister Dean Nalder said the project will address the significant congestion issues along Kwinana Freeway from Roe Highway to Armadale Road including the Roe Highway westbound merge with Kwinana Freeway.

Mr Briggs said the project will significantly reduce congestion on Perth's major southern arterial road and slash travel times for motorists.

“The Kwinana Freeway southbound between Roe Highway and Armadale Road no longer has the capacity to meet today's demands which is impacting on the economic output of Perth's road network.

“This upgrade along with our other multi-billion dollar infrastructure investments like the Perth Freight Link and Gateway WA will unlock the productive capacity of Western Australia and create thousands of new jobs.

“Construction works are expected to commence in September 2014 and be completed in mid-2015,” Mr Briggs said.

Western Australian Transport Minister Dean Nalder said the corridor between Roe Highway and Armadale Road had experienced strong traffic growth, which was expected to continue.

“Large numbers of vehicles exit at Armadale Road, so the third southbound lane should improve the existing peak hour congestion conditions,” Mr Nalder said.

“Reducing congestion is vital to improving productivity, lowering business costs and improving the economy to create jobs.

“Construction of the third southbound lane along the 4.2km section of the freeway is similar to the previously completed section between Leach and Roe Highways.

“While this important work will have a short term disruption on traffic flows, Main Roads will work with Lend Lease Engineering to determine the best way to maintain traffic movements for all road users,” Mr Nalder said.

The $62million project is being jointly funded by the Australian Government and the WA State Government, with each committing $31million.

Fact File

  • Kwinana Freeway southbound will remain as two lanes under the bridge at Roe Highway. Traffic modelling has shown a greater demand for the third lane south of Roe Highway, with significant numbers of vehicles entering the freeway at this location.
  • The freeway services the southern suburbs of Perth, and links the city to the south west region of the state.
  • By 2025 the Fremantle Outer Harbour is expected to be in operation, increasing freight demand on the freeway. However, the upgrade will cater
