Construction began on the widening of Armadale Road in the city of Perth in Western Australia.
Under the project, a 6.9km section of Armadale Road will be upgraded to a dual carriageway in each direction.
The Malcolm Turnbull government is providing AUD116m ($90.52m) for the project, and the McGowan government is offering AUD29m ($22.63m).
Western Australia Premier Mark McGowan said that the upgrade to Armadale Road will ease congestion in the southern suburbs, improve safety, create jobs for Western Australians, and lead to more predictable journey times for road users.
McGowan said construction on at least eight major road projects across Perth will begin in 2018 and many others will reach planning completion and be released for tender.
He said: “The State government is getting on with the job of delivering important upgrades across Perth’s suburbs to complement our METRONET vision.”
Federal Minister for Urban Infrastructure and Cities Paul Fletcher said the project will provide a safer, smoother journey for more than 27,000 vehicles that use Armadale Road each day between Tapper Road and Warton Road.
He said the project will support more than 850 direct and indirect jobs.
Fletcher said: “The upgrade of this important traffic corridor will ensure motorists and truck drivers have a safer, more efficient link in south Perth’s increasingly busy road network.
“It will also transform the strategic freight route from a single carriageway road suited to a semi-rural environment to a dual carriageway urban road able to service the ongoing commercial and residential development of the area.”
State Transport Minister Rita Saffioti said the Armadale Road project is part of a series of major upgrades that will address Perth’s most congested roads and create much-needed jobs.
She said that the upgrade is one of a pipeline of road projects getting underway in 2018, together worth $750m and expected to create around 4,500 jobs.
Saffioti said: “In coming years, commuters will notice a real difference in journey times as we see the string of projects reach completion.
“The Armadale Road widening in particular will provide better access to new residential developments, Cockburn Train Station, Cockburn Gateway Shopping Centre and the Jandakot Industrial Area.”
The project is expected to be completed in late 2019 and is being constructed by the Metropolitan Road Improvement Alliance.
