The WA Government’s plans to relieve congestion along Armadale Road and the southern suburbs are progressing, with a contract awarded for delivery of the Armadale Road to North Lake Road bridge project.
The Armadale Access Alliance, a consortium comprising Laing O’Rourke and BG&E in partnership with Main Roads, will deliver the $134 million contract following a competitive tendering process.
The project will see the construction of a new bridge over Kwinana Freeway connecting Armadale Road and North Lake Road, creating 1,400 jobs. The existing interchange at Kwinana Freeway is the 10th most congested intersection in the metropolitan area.
Armadale Road will also be upgraded from Tapper Road to Kwinana Freeway, passing over the intersection of Tapper Road with a new bridge, and under the intersection of Solomon Road via a trench structure.
Both projects were announced as part of the ‘Boosting Jobs, Busting Congestion’ package launched by the WA Government, when funding was redirected from the flawed Perth Freight Link project.
Upon completion, the project will enable road users to bypass congestion at the Cockburn Gateway Shopping Centre, addressing congestion at the Kwinana Freeway, Armadale Road and Beeliar Drive interchange, Perth’s fifth most congested intersection.
Construction of the project will begin in late 2019 following a period of detailed design.
In addition to the North Lake Road bridge, work is progressing on the final section of the $145 million Armadale Road widening project, which created 850 jobs.
The four-way signalised Armadale Road and Nicholson Road intersection will soon be converted to a roundabout with a four-lane bridge (two lanes in each direction) over Nicholson Road.
This will provide free-flowing traffic movement on Armadale Road, with on and off-ramps from the roundabout below providing connectivity.
A number of sections of new carriageway are also complete as part of the broader Armadale Road widening project from Tapper Road and Anstey Road, including:
- Two kilometres of road between Ghostgum Avenue and Warton Road;
- Two kilometres of road between Warton Road and west of Rossiter Avenue; and
- Half a kilometre of road west of Anstey Road roundabout.
