This project sees the construction of a new bridge over the Kwinana Freeway, including the installation of free-flowing lanes on Armadale Road through to Solomon Road.
A grade-separated roundabout is also being installed at the intersection of Armadale Road and Solomon Road, and Armadale Road and Tapper Road, allowing traffic to crossover at differing heights.
Commuters can also look forward to an upgrade to the Cockburn Central Station eastern car park with 1100 bays, including ACROD and future electronic vehicle parking, motorcycle bays, bike lockers, and a kiss n’ ride drop off zone.
The project has programmed the car park works in stages to reduce inconvenience to commuters and motorists as much as possible and to ensure some car parking remains available to station patrons during construction.

Knock Place closure and Cockburn Central Station eastern car park upgrade
As part of the Armadale Road to North Lake Road Bridge project, a long-term closure of Knock Place and Hutt Link is required in order to progress works for the construction of the new intersection at Armadale Road and Solomon Road, and to reconfigure the existing Cockburn Central Station eastern car park.
The following detours will be in place:
- Knock Place closure Wednesday 16 September 2020 to project completion late 2021
- Hutt Link closure November 2020 to project completion late 2021
- Solomon Road traffic change September 2020 to mid-2021
- No right turn from Armadale Road
- Left turn only from Solomon Road onto Armadale Road
- Commercial precinct
- Access unchanged from Armadale Road
- November 2020 replacement road accessible from Cockburn Central station car park to commercial precinct, see purple arrows in the map above.
Kwinana Freeway, between Beeliar Drive and Berrigan Drive
A new detour for the pedestrian and cyclist path, between Beeliar Drive and Muriel Court is scheduled to commence on Saturday 1 May with signed detours in place.
We ask all pedestrians and cyclists to pay extra attention to the changed conditions and allow additional travel time.
Closure of Berrigan Drive on-ramp 13 June to 2 August 2021
An extended closure of the Berrigan Drive on-ramp to Kwinana Freeway Southbound is required from 7pm Sunday 13 June to Monday 2 August 2021 to enable a suitable safe work zone for the METRONET Thornlie-Cockburn Link project.
While this closure is in place, the Armadale Road to North Lake Road Bridge project will complete construction of the new Collector-Distributor road between Berrigan Drive and Armadale Road, removing the requirement for further weekend closures of the on-ramp in August and September.
Berrigan Drive traffic intending to travel onto Kwinana Freeway Southbound will be encouraged to follow the signed detour eastbound via Jandakot Road or westbound via North Lake Road.
Please see the map for detour route. Signed detours will be in place.
