The interchange is part of a program of congestion relief in Perth’s eastern suburbs, the interchange will also dramatically improve safety for almost 60,000 vehicles that pass through it daily.
The project will lover Roe Highway by around nine metres to pass beneath Kalamunda Road. Connections between the two roads will be retained through roudnabouts on Kalamunda Roads as well as on and off ramps to the highway.
The $86 million project is jointly funded with the Australian Government committing $68.8 million and the Western Australian Government $17.2 million.
Federal Minister for Population, Cities and Urban Infrastructure Alan Tudge said the project would make life easier for thousands of drivers.
“It will improve traffic flow and speed up travel times, particularly for freight operators travelling on the Roe Highway, which is a key strategic route across Perth’s eastern suburbs,” Mr. Tudge said.
Western Australian Minister for Transport and Planning Rita Saffioti said the road improvement program in Perth’s eastern suburbs was gathering pace, with NorthLink and New Lord Street close to completion and the Reid Highway Dual Carriageway project underway.
“This project will address congestion and improve journey times through one of the last remaining signalised intersections on Roe Highway,” Ms. Saffioti said.
“This will be closely followed by the now fully funded interchange at the intersection of Great Eastern Highway Bypass, which is currently undergoing project development.”
The interchange will also link a shared pedestrian and cyclist path on the highway’s eastern side to local roads. Following an additional state government funding commitment in March 2019 the path will extend to Berkshire Road completing a missing link in the shared path network along Roe Highway.
Construction will increase over the coming months, with bridge-building activity to begin in the New Year.
New drainage, street lighting and other supplementary works will complete the interchange. Project completion is scheduled for early 2021.
