BMD Constructions has been awarded a $49.4 million state government contract to widen a section of the Mitchell Freeway, beating CPB Contractors and WBHO Infrastructure for the work.
Under the contract, BMD will widen the southbound section of the freeway from Cedric Street to Vincent Street.
The works will provide seven kilometres of additional lane in the southbound direction to improve congestion in the area.
Construction is expected to begin soon, with completion by the end of 2019.
The project forms part of a $2.3 billion WA Infrastructure package.
In October, Transport Minister Rita Saffioti said the Mitchell Freeway carried some of the highest traffic loads in Perth - up to 180,000 vehicles per day – making the work vital to keep traffic flowing.
“The project works will include an additional lane for seven kilometres, reducing the need for merging bottlenecks and improving congestion and safety along this stretch of freeway,” she said.
Canberra is contributing $32 million towards the upgrade, with $8 million coming from the state government.
