The Government of Western Australia has announced the opening of Tonkin Highway flyover at Marshall Road in Western Australia.

The new flyover is expected to provide a quick and safer journey route to Perth motorists between Ballajura, Malaga and Beechboro.

It will form part of a $821m ($594m) transport link between Morley and Muchea called the NorthLink WA project.

The project is expected to be completed by the end of next year and aims to divert 80% of heavy vehicular traffic away from Great Northern Highway.

“The Marshall Road flyover will ultimately deliver faster, safer travel times for motorists.”

Cyclists and pedestrians will be redirected onto the flyover through a temporary footpath along the northern side of Marshall Road that links to the existing path on Beechboro Road North.

The flyover will also disconnect traffic from the works so that construction on Tonkin Highway near Marshall Road can progress unhindered.

Federal minister for cities, urban infrastructure and population Alan Tudge said NorthLink WA was part of plans to cut congestion across Perth.

“The flyover will also mean easier access in the Swan Valley for residents and the 600,000 tourists who visit the area each year,” Tudge added.

WA transport minister Rita Saffioti said the flyover at Marshall Road was a welcome safety initiative as grade separation is safer than a signalised intersection, eliminating the potential for conflict and allowing for smoother traffic flow.

Saffioti said: “As part of the overall network of changes, the Marshall Road flyover will ultimately deliver faster, safer travel times for motorists.”
