Main Roads Western Australia has awarded the $51 million design and construction contract for the intersection of Roe Highway and Kalamunda Road.
Georgiou Group have been awarded the contract after a competitive tender process in late 2018.
The project will see Roe Highway lowered by approximately nine metres to pass beneath Kalamunda Road.
Connectivity between the two roads will be retained with two roundabouts on Kalamunda Road as well as on and off ramps to the highway.
Detailed design of the project is currently underway with construction anticipated to begin in late 2019.
Federal Minister for Population, Cities and Urban Infrastructure Alan Tudge said the new interchange was another essential component for the Federal Government’s investment in Western Australia’s road and rail infrastructure.
“This interchange will bust congestion and improve traffic flow and freight efficiency on what is a strategic route across Perth’s eastern suburbs,” Mr Tudge said.
A principal shared path will also be constructed on the eastern side of the highway to provide local connectivity for pedestrians and cyclists.
New drainage, street lighting and other supplementary works will complete the interchange.
Site surveys and geotechnical investigations for this additional connection are underway, with construction to begin in August.
The project will eliminate one of the last remaining signalised intersections on the highway.
The intersection currently is heavily congested and has a higher than average number of crashes.
The project is one of 18 announced as part of the $2.3 billion ‘Boosting Jobs, Busting Congestion’ infrastructure package announced in May 2017.
Completion of the project is scheduled for early 2021.
