The Federal and Victorian governments have lifted their combined spend on the Western Highway Upgrade to roughly $1.17 billion, with works on a near 12-kilometre stretch between Buangor and Ararat in western Victoria scheduled to start this month and finish by 2029. The job adds a lane in each direction, plus new centre medians and safety barriers.
The figures were reported by Roads & Infrastructure, which said the Buangor to Ararat works are going ahead on the back of an extra $446 million joint investment from the Federal and State governments in the 2026/27 budgets.
That section sits at the western end of a program that has already duplicated the highway between Ballarat and Buangor. The Western Highway is described in the report as one of the busiest undivided national highways in the country, and a main freight and tourism run for western Victoria.
”Far too many accidents”
Federal Minister for Infrastructure, Transport, Regional Development and Local Government Catherine King put the case for the work in blunt terms.
“This dangerous section of road has seen far too many accidents and tragic fatalities,”
King said.
“After years of delays, it’s time to get this done.”
The minister’s portfolio sits with the federal infrastructure department at infrastructure.gov.au, which administers the Commonwealth’s share of road funding to the states.
What a duplication job looks like on the ground
Duplicating a highway isn’t the same animal as building one. The alignment already exists, so the bulk of the money goes into a second carriageway built alongside live traffic: clearing and topsoil strip, bulk earthworks, drainage, then pavement layers, followed by the median and barrier installation the report flags, and finally line marking and tie-ins at each end.
The existing highway stays open the whole time. That means traffic management is not a side job on this one, it runs for the life of the contract, with speed restrictions, lane shifts and site access points that have to be moved as the works front advances along the 12 kilometres.
For anyone in civil work around Ararat, Beaufort and Ballarat, the timing is the useful bit. A start this month against a 2029 completion is a work window of a bit over two years, in a corridor where plant and crews have already been through the Ballarat to Buangor duplication. That’s long enough to be worth gearing up for, which is a different calculation to a six-month resheet job.
The Roads & Infrastructure report doesn’t name a head contractor or break down the package, so anyone chasing subcontract work on earthworks, drainage, barrier installation or traffic control will be watching for the procurement detail rather than acting on the announcement.
The number worth keeping
The Federal and Victorian governments’ total investment in the Western Highway Upgrade has reached roughly $1.17 billion, with $446 million of that committed through the 2026/27 state and federal budgets, Roads & Infrastructure reported in November 2026.
It’s a reminder of how the regional road pipeline actually behaves. Money lands in a budget, then the works front shows up on a stretch of bitumen a year or two later, and the sequence repeats down the corridor section by section. The Ballarat to Buangor duplication came first, Buangor to Ararat is next.
Worth noting that the figures above come from a single trade report. A Victorian Government confirmation of the funding split and the contract packaging would be the solid ground to plan off.
What to watch
Two things matter for anyone with a stake in this. The first is the contract award and package structure, which decides whether local civil outfits get a look in or whether the work sits inside one big tier-one scope. The second is the traffic management plan, because every operator, truckie and crew running between Ballarat and Horsham will be living with lane closures on that 12 kilometres until 2029.
If you cart freight on the Western Highway, start building the delays into your run times now. If you turn dirt for a living in the Wimmera and Central Highlands, the next announcement to read closely is the one with a contractor’s name on it.
