Abernethy Road Upgrade

Designed to create a safer, more accessible and less congested avenue into the Byford town centre, the project involves widening a 3.1km section of Abernethy Road to accommodate a four-fold increase in vehicle traffic by 2030.

Telecommunications services were installed late last year, while water and electrical service relocation remains on schedule. Wormal Civil is now focussed on above-ground works. Which began with construction of a roundabout and drainage systems near Kardan Boulevard, and with installation of a drainage culvert at Soldiers Road.

Shire President Cr Michelle Rich said the project was on track for completion later this year with the lengthy and complex task of relocating underground services largely complete.

“Residents will now really start to see the project take shape as work ramps up on the above-ground phase,” Cr Rich said.

“We’re really excited that the project is forging ahead because this is something the community desperately needs. By reducing congestion the road will become much safer for both motorists and pedestrians, while also making it easier for people to get to and from the Byford town centre. That will in turn help local business and contribute to the growth of a vibrant, thriving shopping precinct.”

The $19 million project is partly funded through contributions from the National Stronger Regions Fund, Main Roads WA and the Shire of Serpentine Jarrahdale.
