In the lead-up to last year’s Canning by-election, the two councils announced the Community Connecting South (CCS) partnership to address congestion and improve access to major hubs.
The aim was to secure $290 million in funding to upgrade Armadale Road to a dual carriageway between Verde Drive in Jandakot and Anstey Road in Forrestdale and build another bridge over the freeway to link North Lake Road and Armadale Road.
The Federal and State governments committed $145 million for the roadworks on Armadale Road, but the bridge remains unfunded.
Cockburn Mayor Logan Howlett said the two councils were looking to change that with a federal election on the horizon.
“The campaign to complete CCS will feature heavily in the lead up to the Federal Election,” he said.
“The upgrade of Armadale Road and the associated bridge works are as critical to Armadale residents as it is to Cockburn residents, with the road running right through the new seat of Burt.”
Armadale Mayor Henry Zelones said his council was right behind the push.
“While securing $145 million for the full duplication of Armadale Road was a major victory for the Community Connect South campaign, the job is only half done,” he said.
“As we head towards the next Federal and State elections, we will continue our campaign to ensure this second piece of vital infrastructure is on the government agenda.”
A new design for a re-aligned Armadale Road and the bridge over the freeway is in planning.
The bridge had been estimated at as much as $160m, but the estimate will be revisited once the new design is complete.
Mr Howlett said completion of the full scope of the CCS would help ease traffic congestion which had stalled development of Cockburn Central.
