Western Highway (Victoria)

Western Highway commences at the state border with South Australia as a continuation of Dukes HighwayatVictoria and heads in a south-easterly direction as a two-lane, single carriageway rural highway with numerous overtaking lanes and passes through the agricultural centres of Nhill, Horsham, Stawell and Ararat. Just west of Buangor, Western Highway becomes Western Freeway and widens to a four-lane, dual-carriageway road, and begins bypassing most of the towns the old alignment of the highway used to serve, passing Ballarat, Ballan and Bacchus Marsh, before reaching the western fringes of suburban Melbourne outside Melton; major intersecting roads are grade-separated, however there remain minor intersections at-grade, and cycling is permitted on the sealed shoulder along most of the freeway. The freeway continues through the suburbs of Rockbank and Ravenhall, before eventually terminating at the interchange with Western Ring RoadinDerrimut.

Plans are underway for the end of this freeway to be extended from the current terminus just after the Buangor bypass westward towards and eventually to Stawell.

The passing of the Country Roads Act of 1912^[7] through the Parliament of Victoria provided for the establishment of the Country Roads Board (later VicRoads) and their ability to declare Main Roads, taking responsibility for the management, construction and care of the state's major roads from local municipalities. (Main) Ballarat Road was declared a Main Road, from Footscray via BraybrooktoMelton on 30 December 1913,^[1] and from Melton via Bacchus Marsh, Ballan and BungareetoBallarat East on 24 August 1914;^[8] Horsham (-Dimboola) Road from HorshamtoDimboola, (Dimboola-) Nhill Road between Dimboola and Nhill and Nhill-Kaniva-Border Road between Nhill through Kaniva to the South Australian border, were declared as Main Roads on 17 March 1915;^[9] Ballarat-(Ararat-)Stawell Road between Ballarat West through Beaufort and ArarattoStawell was declared a Main Road on 31 May 1915.^[10]

The passing of the Highways and Vehicles Act of 1924^[11] provided for the declaration of State Highways, roads two-thirds financed by the State government through the Country Roads Board. Western Highway was declared a State Highway on 1 July 1925,^[2] cobbled from a collection of roads from Melbourne through Ballarat, Ararat, Stawell, Horsham, and Dimboola to the interstate border at Serviceton (for a total of 244 miles), subsuming the original declarations of Main Ballarat Road, Ballarat-Stawell Road, Horsham-Dimboola Road, Dimboola-Nhill Road, and Nhill-Kaniva-Border Road as Main Roads. Western By-pass Road was opened in 1969 through Pykes Creek Reservoir, but this was being referred to as Western Freeway by the time the Gordon and Bacchus Marsh bypasses were completed in 1972.

The Whitlam government introduced the federal National Roads Act 1974,^[12] where roads declared as a National Highway were still the responsibility of the states for road construction and maintenance, but were fully compensated by the Federal government for money spent on approved projects.^[12]: S7 As an important interstate link between the capitals of Victoria and South Australia, Western Highway was declared a National Highway in 1974.^[13]

The passing of the Road Management Act 2004^[14] granted the responsibility of overall management and development of Victoria's major arterial roads to VicRoads: in 2004, VicRoads re-declared the road as Western Highway (Arterial #6520) between the border with South Australia at Serviceton and Buangor,^[5] and as Western Freeway (Freeway #1520) between Buangor and Western Ring Road, Derrimut.^[6]

Western Highway was signed as National Route 8 in 1955, then as National Highway 8 when upgraded to a National Highway in 1974. With Victoria's conversion to the newer alphanumeric system in the late 1990s, the section between Burrumbeet and Ardeer (where it met the Western Ring Road) was re-signed as National Highway M8, and between Burrumbeet and the border as National Highway A8; it was left as National Highway 8 east of the ring road along its original alignment into central Melbourne. Once the Deer Park bypass was opened in 2009, National Route M8 was re-routed onto the new bypass and the old alignment of Western Highway between Ravenhall and Footscray was re-declared as Ballarat Road and replaced with Metropolitan Route 8; VicRoads altered National Highway M8 to route M8 and National Highway A8 to route A8 in 2013, bringing their design in line with the rest of the state.^[15] Route M8 was extended further west when the next section of converted freeway to Buangor opened in 2016. Former alignments of Western Highway are generally designated sequentially from route C801 to C805, or as Metropolitan Route 8 (within suburban Melbourne).

The newest sections of freeway-standard dual carriageway opened on 6 March 2015 for the Ballarat to Beaufort section (running 25 kilometres (16 mi) in length), and on 17 April 2016 for the Beaufort to Buangor section (running 21 kilometres (13 mi) in length). The first section runs between the end of the Ballarat bypass between a new interchange with the Avenue of Remembrance (route C805) in Burrumbeet to just outside the eastern side Beaufort (including a bypass of Trawalla) providing 156 kilometres (97 mi) of freeway standard road between Melbourne and Beaufort. The second section runs between just outside the western side of Beaufort to just after the Buangor bypass, where it becomes a single carriageway again running all the way to Ararat, providing a further 21 kilometres (13 mi) of freeway standard between Beaufort and just beyond Buangor.

The Melbourne section of Western Highway is shown in the 1969 Melbourne Transportation Plan as part of the F12 Freeway corridor.

• 2016 – Beaufort to Buangor opened to traffic in April 2016 adding a further 21 kilometres (13 mi) of dual carriageway to the existing freeway, which includes the Buangor bypass.

The Deer Park Bypass opened on 5 April 2009 in the western suburbs of Melbourne. The freeway links Western Freeway at Ravenhall and the Western Ring RoadinDerrimut. This 9.3 kilometre freeway was estimated to cost A$333 million which also includes a grade separated (or "full diamond") interchange at Leakes Road in Rockbank.

The purpose of the freeway bypass is to move traffic off Ballarat Road, which leads to the Western Ring Road. Due to the strong population growth of about 8.7 per cent and subdivision in Deer Park and Sunshine, the surrounding suburbs and the seven traffic signals between the Western Ring Road and the start of Western Freeway, substantial long and very frustrating delays were created for the 70,000 vehicles per day with 10 per cent of this consisting of heavy vehicles.

The bypass had been proposed since the completion of the Western Ring Road, the project stalled due to funding quarrels between the Federal and State Governments. In 2004, the Federal government announced that the Deer Park Bypass would be built as part of a $1.4 billion project "package grant" to Victoria. It was anticipated that more than 15 min of travel time would be saved when travelling through Deer Park, via Ballarat Road. Construction started on the Deer Park bypass in August 2006,^[39] work being carried out as a joint venture by Leighton Contractors and VicRoads, in construction with two contracts. The first stage, allowing westbound traffic over the new bridge at the Ravenhall end of the new freeway, opened in December 2007.^[40]

It was announced on 4 March 2009 that the Deer Park Bypass would open in early April 2009, with the new freeway link on track to open more than eight months ahead of schedule. On that day, Roads and Ports Minister Tim Pallas and Federal Member for Gorton Brendan O'Connor MP inspected works from the new bridge over the Ring Road at Sunshine West and Tim Pallas announced that the $331 million Deer Park Bypass would open to the public on Sunday 5 April 2009.^[41]

The section of road through Anthony's Cutting between Bacchus Marsh and Melton was one of the most dangerous sections of the route, and was not of modern freeway standard. The steep hills and tight curves along the 5 kilometre long stretch of road resulted in 21 serious crashes in the five years to 2010.^[42] More than 29,000 vehicles, including more than 4000 freight vehicles, travelled the highway section daily.^[43] The new route opened to traffic on 27 June 2011, nine months ahead of schedule.^[44]

The project included:^[45]

• Extension of Woolpack Road north from Bacchus Marsh Road to a new interchange on Western Freeway, including a bridge over the Lerderderg River.
• An overpass carrying Bulmans Road over the existing Western Freeway.
• An overpass taking Hopetoun Park Road across the new freeway, with Melbourne-bound on and off ramps.
• Freeway bridges spanning Djerriwarrh Creek, and Cowans Road / Pyrites Creek.

The original project scope included a diamond interchange at Bulmans Road that has not been built, while the ramps at Hopetoun Park Road were not included but was later added.^[46] The extension of Woolpack Road has been delayed due to controversy over need to clear trees in the heritage listed Avenue of Honour at Bacchus Marsh.^[47]

Realignment of the road through this section had been proposed far back as 2001, when a group of 10 local councils said the realignment could cost just $65 million to build.^[48] By 2006 the cost was estimated to be $85 million, with federal Roads Minister Jim Lloyd stating that the project would receive serious consideration for funding in the 2009 AusLink document, subject to support from the State Government.^[49] Construction commenced in February 2010, funded by $160 million from the Australian Government and $40 million from the Victorian Government.^[50]

In 2001 work started on a 4.2 kilometre long deviation at Armstrong (on the Adelaide side of Ararat), involving 200,000 cubic metres of earthworks and a new bridge over the main Melbourne–Adelaide railway. Previously high vehicles could not travel under the rail overpass and were forced to detour around it, in addition the poor road conditions led to a number of accidents and fatalities.^[51] Costing $6.1 million the work was completed by 2003.^[52]

As of 2017^[update], several at-grade intersections remained on the "freeway", particularly in the areas near Rockbank and at Woodmans Hill just to the east of Ballarat.

• Proposed upgrade and safety improvements Rockbank to Melton, to be funded by Auslink 2 (2009–2014)[1].
• Proposed extension west from the current freeway terminus in the Melbourne side of Beaufort West through to Ararat and eventually to Stawell, also part of Auslink 2. Beaufort to Buangor was completed in April 2016. Buangor Bypass completed in mid-2016, and Buangor to Ararat was expected to start in early 2017.^{[38][needs update]}

Duplication of Western Highway between Ballarat and Stawell was proposed to be completed between 2009 and 2014, to be funded by Auslink 2.^[53] At the end of 2016, some parts were still in early planning, including the bypasses at Beaufort and Ararat.^{[54][needs update]}

The clearing of wide swathes of the ancient red gums by VicRoads near Beaufort resulted in expressions of community concern, including public meetings. In 2015, two women chained themselves to a red gum tree for 4½ hours near Buangor, 74 kilometres (46 miles) west of Ballarat, to draw attention to the issue. Isabel Mackenzie, a long-term resident of the area, said she was concerned at the environmental impact of removing trees that are hundreds of years old. Helen Lewers said that VicRoads should reroute the highway between Buangor and Stawell to preserve the native roadside vegetation.^[55]
