Highways in Australia National Highway • Freeways in Australia Highways in Victoria Highways in New South Wales

Calder Highway is a rural highway in Australia, linking Mildura and the Victoria/New South Wales border to Bendigo, in North Central Victoria. South of Bendigo, where the former highway has been upgraded to freeway-standard, Calder Freeway links to Melbourne, subsuming former alignments of Calder Highway; the Victorian Government completed the conversion to freeway standard from Melbourne to Bendigo on 20 April 2009.

Calder Alternate Highway connects to Calder Highway at either end – just north of Ravenswood, and at Marong – and provides a bypass west of Bendigo.

Calder Highway commences at the intersection with Silver City Highway in Curlwaa (officially a branch of Silver City Highway, yet sign-posted as Calder Highway) and crosses the Murray River into Victoria over the Abbotsford Bridge, then continues in a southeasterly direction as a two-lane, single carriageway rural highway through Merbein and intersects with Sturt Highway just outside the major regional town of Mildura, where widens to a four-lane, dual-carriageway road through southern Mildura and Irymple, in the state's north-west. It narrows back to a two-lane single carriageway road and continues in a southerly direction, meeting Mallee Highway at Ouyen, then in a south-easterly direction through Sea Lake, Wycheproof, Charlton and meeting the northern end of Calder Alternative Highway at Marong eventually to the western suburbs of Bendigo, where it widens to a four-lane, dual-carriageway road as it weaves through the rural city, intersecting with Loddon Valley Highway and meeting with Midland Highway, where it narrows back to a single carriageway road and shares a concurrency through south-western Bendigo, widening again to a dual carriageway through Kangaroo Flat to eventually meet the southern end of Calder Alternative Highway at an interchange in Ravenswood.

Calder Highway becomes Calder Freeway at the Ravenswood interchange and continues in southerly direction as a four-lane, dual-carriageway rural freeway which bypasses the towns along the highway's former alignment. Calder Freeway passes Harcourt - where the shared concurrency with Midland Highway ends, as it travels in a south-westerly direction to the major regional centres of Castlemaine, Ballarat, and Geelong - and continues in a south-easterly direction past Elphinstone, Kyneton, Woodend and Gisborne, to reach the western suburban fringe of Melbourne. It continues in a south-easterly, and then easterly, direction past Calder Park Raceway and Keilor, before eventually terminating at an interchange with Tullamarine Freeway at Airport West.

Within the urban section of Calder Freeway (between Kings Road and Tullamarine Freeway), the standard travel time, in each direction, is 10 minutes; 5 minutes between Kings Road and the Western Ring Road and 5 minutes between the Ring Road and Tullamarine Freeway.

Between Red Cliffs and Wycheproof the highway has a speed limit of 110 km/h.

The passing of the Country Roads Act of 1912^[5] 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. (Melbourne-) Bendigo Road was declared a Main Road over a period of months, from 30 December 1913 (Castlemaine via Harcourt to Ravenswood),^[1] to 30 November 1914 (from Keilor through Diggers Rest to Gisborne, and from Woodend through Kyneton and Elphinstone to Castlemaine),^[6] to 20 September 1915 (from Ravenswood to Bendigo);^[7] (Ouyen-) Sea Lake Road from Ouyen to Mittyack, (Ouyen-) Mildura Road from Ouyen to Hattah, and Wycheproof-Sea Lake Road from Wycheproof to Sea Lake were declared Main Roads on 14 December 1914;^[8] and (Charlton-)Wycheproof Road between Charlton and Wycheproof was declared a Main Road on 28 May 1915;^[9] and Charlton-(Bridgewater-)Bendigo Road was declared a Main Road, between Bridgewater and Wedderburn to Charlton on 28 May 1915,^[9] and between Bendigo and Bridgewater on 20 September 1915.^[7]

The passing of the Highways and Vehicles Act of 1924^[10] provided for the declaration of State Highways, roads two-thirds financed by the State government through the Country Roads Board. North Western Highway was declared a State Highway on 1 July 1925,^[2] cobbled from a collection of roads from Melbourne through Kyneton, Castlemaine, Bendigo, Sea Lake and Ouyen to Mildura (for a total of 324 miles), subsuming the original declarations of Melbourne-Bendigo Road, Charlton-Bridgewater-Bendigo Road, Charlton-Wycheproof Road, Wycheproof-Sea Lake Road, Ouyen-Sea Lake Road and Ouyen-Mildura Road as Main Roads. North-Western Highway was renamed Calder Highway in 1928, after William Calder, chairman of the Country Roads Board from 1913–28.^[11] In the 1959/60 financial year, another section from Elphinstone to Harcourt was added as a deviation bypassing Castlemaine, along the former Elphinstone–Harcourt Road^[12] (already having been declared a Main Road by the Country Roads Board in 1937/38 financial year^[13]); the previous alignments of Calder Highway from Elphinstone to Castlemaine, and Castlemaine to Harcourt, were subsumed into Pyrenees Highway and Midland Highway respectively. The first section of Calder Freeway in Melbourne was opened in 1972, over time stretching west to ultimately become a project to convert the road to freeway standard all the way to Bendigo; the freeway upgrade has made sections of the original Calder Highway redundant, either incorporated into the new freeway or acting as local access roads. Calder Alternative Highway was declared in 9 May 1983, along the former Ravenswood–Marong Road.^[14][15]

Calder Highway was later signed National Route 79 in 1955^{[citation needed]}; when Midland Highway was allocated State Route 149 in 1986, it shared it as a concurrency along Calder Highway between Harcourt and Bendigo. With Victoria's conversion to the newer alphanumeric system in the late 1990s this was altered to route A79 for the highway portion, and route M79 for the freeway portion into Melbourne (and the concurrency with Midland Highway was replaced with route A300); the New South Wales section was left unallocated when they switched to the alphanumeric system in 2013. Calder Alternative Highway was signed Alternative National Route 79 between Ravenswood and Marong, and was later replaced by route A790.

Originally, Calder Highway ran through northwestern Melbourne as an undivided highway, ultimately through Niddrie as Keilor Road and terminating in Essendon; traffic continued south along Mount Alexander Road to reach central Melbourne. Keilor Road – already heavily congested and supporting a tram line – was eventually bypassed by a freeway-standard road in 1972 to terminate at a junction with Lancefield Road (later upgraded to Tullamarine Freeway), rejoining Calder Highway at the western end of Niddrie;^[16] the freeway-standard was extended further west to East Keilor (the future location of the Western Ring Road interchange) in 1975, and to Keilor by the early 1980s. However, it was not until the 1990s that work began to duplicate the rest of the highway to Bendigo.

The Howard government broadened the criteria under which roads qualify for Commonwealth road funding by introducing Roads of National Importance program in the 1996–97 financial year^[17] where such declarations were based on the recognition that roads outside the National Highway system also provide social benefits, and were funded jointly with the States and Territories usually on a 50:50 basis. As a major road link between Melbourne, Bendigo, and the state's northwest, supporting the region's primary manufacturing and tourism industries, Calder Highway was declared a Road of National Importance between Melbourne and Bendigo in December 1996.^[18][19]

The passing of the Road Management Act 2004^[20] granted the responsibility of overall management and development of Victoria's major arterial roads to VicRoads: in 2004, VicRoads re-declared the road as Calder Alternative Highway (Arterial #6200) between Ravenswood and Marong,^[21] and in 2011 as Calder Highway (Arterial #6530) between the border with New South Wales at Yelta and the interchange with Calder Alternate Highway and Ravenswood Street in Ravenswood,^[22] and as Calder Freeway (Freeway #1530) between Ravenswood and Tullamarine Freeway, Airport West.^[23]

The Calder Highway between the Melton Highway and the Western Ring Road is shown in the 1969 Melbourne Transportation Plan as part of the F4 Freeway corridor, which extends past the Tullamarine Freeway and Bell Street to Templestowe.^{[citation needed]}

In 2008, VicRoads completed the widening of the Calder Freeway from the Western Ring Road to Melton Highway. The road was widened from 2 lanes each direction to 3 lanes in each direction. The speed limit was reduced permanently from 100 km/h to 80 km/h.^[45] The 80 km/h limit applies northbound from Keilor Park Drive to Melton Highway,^[46] and southbound it applies from the Green Gully Road bridge to just prior to the Western Ring Road interchange. In October 2010, it was announced that as part of a year long trial, the speed limit on this section of freeway will be increased back to 100 km/h in off-peak times (8pm-5am), with 30 variable speed limits to be installed along the stretch of freeway^{[citation needed]}. A further upgrade completed in 2012 resulted in a new interchange at Kings Road (the freeways's urban / metropolitan limits) and closure of three at grade intersections in the area. Despite these upgrades the 80 km/h speed limit remained in place.
