Tenders have been called for phase one of the Stephenson Avenue Extension project - extending Stephenson Avenue from Scarborough Beach Road up to Sarich Court in Osborne Park.
The Stephenson Avenue Extension project will be delivered in stages, with the first phase managed by the City of Stirling.
It features two lanes in each direction with traffic signalised intersections, new local road connections to Ellen Stirling Boulevard at Oswald Street and Howe Street, on-street parking, pedestrian and cycling facilities, as well as streetscaping.
Phase two of the project - extending Stephenson Avenue from Sarich Court to Cedric Street incorporating a new interchange at the Mitchell Freeway - is in planning and development, with construction anticipated to begin in 2021, subject to all relevant approvals.
The final phase of the project - Sarich Court to Cedric Street will be delivered by the City of Stirling.
Premier Mark McGowan said the Stephenson Avenue Extension Project will encourage investment in the Stirling City Centre, one of the largest business precincts outside the Perth central business district.
"With the design, geotechnical investigations and environmental approvals now complete phase one of the Stephenson Avenue Extension project is set to begin construction in mid 2020.
"Not only will this project create and support local jobs, it reflects our commitment to ensuring key infrastructure is in place that will help unlock private investment in a key CBD hub outside of Perth."
Federal Minister for Infrastructure, Cities and Transport Alan Tudge said the opening of tenders for the first phase is an important milestone in the start of the Stephenson Avenue project.
"This will kick start the Stephenson Avenue project and further boost job opportunities for Western Australians.
"This new infrastructure will provide improved connectivity, connecting people with jobs and goods to markets, in turn facilitating economic and social improvements for the community."
WA Transport Minister Rita Saffioti said the extension of Stephenson Avenue was just one of the key projects underway in the northern suburbs reducing congestion and boosting local jobs.
"We have undertaken an unprecedented amount of work on key infrastructure projects across the northern suburbs including widening the Mitchell Freeway, upgrading the Ocean Reef Road and Wanneroo Road intersection as well as starting work on the Yanchep METRONET line.
"These works, combined with the planned Stephenson Avenue extension, will create local jobs and mean residents will spend less time on the roads and more time doing important things such as spending time with family and friends.
"The start of work on this extension is the delivery of yet another key election commitment and construction is anticipated to begin later this year."
City of Stirling Mayor Mark Irwin said the extension of Stephenson Avenue is the first step towards creating a gateway to the Stirling City Centre.
"After many years of planning, the City and local community are excited that phase one of the project will begin mid-year.
"The extension will target traffic congestion and open up land for private investment.
"The Stephenson Avenue Extension forms part of our broader plan to transform the Stirling City Centre - an area bounded by Karrinyup road, along Cedric Street and Ellen Stirling Boulevard to Scarborough Beach Road - into a strategic metropolitan centre."
