The Western Highway linking Melbourne and Adelaide is a key corridor through Victoria’s west supporting farming, tourism, manufacturing and a range other services. It is also one of Australia’s busiest highways with freight traffic expected to double by 2025.

As part of the overall $505M Western Highway upgrade, the seven kilometre bypass re-aligned the Western Highway around the township of Buangor with a four lane divided carriageway that included separated interchanges and service roads.

The moderinization brings major benefits for both drivers and the Buangor community by cutting heavy vehicle traffic through the town, improving freight efficiency and boosting local connectivity. Heightened safety was also a prime objective given the highway corridor has seen seven fatalities and 80 casualty accidents in five years.

As the design consultants, Arcadis needed to meet an accelerated and complex construction program that had to incorporate a six month work moratorium, integration with adjacent Western Highway packages, and stringent controls for three new bridges being built over the environmentally sensitive Billy Billy Creek.

Arcadis’ innovative design solutions placed a priority on the protection and retention of the unique red gum vegetation, enhancement of the existing waterway, protection of the Federally listed Dwarf Galaxis fish colony while also enhancing the area’s gateway role to the nearby Grampian Mountains tourist precinct.

Community engagement was just as important and Arcadis worked closely with the township of Buangor, local farmers and businesses to both inform and consult, which resulted in tree planting with schools and building a new BMX track.
