96-1211: The M80 Ring Road (also known simply as the Ring Road or by the names of its constituent parts; the Western Ring Road and the Metropolitan Ring Road ) is a partially complete urban freeway ring road around Melbourne , Australia . This article will deal with the entire length of the corridor for sake of completion, as well to avoid confusion between declarations. The ring road connects Melbourne's western suburbs and northern suburbs to other Victorian urban and rural freeways (the West Gate and Princes Freeways , Western Freeway , Calder Freeway , Tullamarine Freeway and Hume Freeway ), and also relieves freight traffic from Sydney Road , Pascoe Vale Road and Geelong Road . With connections to every major interstate and regional freeway, it has encouraged both industrial and residential growth in Melbourne's western suburbs. A series of major upgrades along

The first North American freeways (known as parkways) opened in the New York City area in the 1920s. Britain, heavily influenced by the railways, did not build its first motorway , the Preston By-pass ( M6 ), until 1958. Most technologically advanced nations feature an extensive network of freeways or motorways to provide high-capacity urban travel, or high-speed rural travel, or both. Many have
288-466: A median separates the opposite directions of traffic. This strip may be as simple as a grassy area, or may include a crash barrier such as a " Jersey barrier " or an "Ontario Tall Wall" to prevent head-on collisions . On some freeways, the two carriageways are built on different alignments; this may be done to make use of available corridors in a mountainous area or to provide narrower corridors through dense urban areas . Control of access relates to
384-497: A National Highway). The Whitlam government introduced the federal National Roads Act 1974 , 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. As an important connecting road between other National Highways linking to the capitals of New South Wales and South Australia,
480-707: A cloverleaf and trumpet interchange when it opened in 1937, and until the Second World War , boasted the longest illuminated stretch of roadway built. A decade later, the first section of Highway 401 was opened, based on earlier designs. It has since gone on to become the busiest highway in the world. The word freeway was first used in February 1930 by Edward M. Bassett . Bassett argued that roads should be classified into three basic types: highways, parkways , and freeways. In Bassett's zoning and property law -based system, abutting property owners have
576-519: 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
672-450: 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
768-620: A freeway, specialized pedestrian footbridges or tunnels may also be provided. These structures enable pedestrians and cyclists to cross the freeway at that point without a detour to the nearest road crossing. Access to freeways is typically provided only at grade-separated interchanges , though lower-standard right-in/right-out (left-in/left-out in countries that drive on the left) access can be used for direct connections to side roads. In many cases, sophisticated interchanges allow for smooth, uninterrupted transitions between intersecting freeways and busy arterial roads . However, sometimes it
864-771: A freeway-standard ring road encircle Melbourne from Laverton North in the south-western suburbs to Frankston in the south-eastern suburbs. The Western Ring Road officially begins at the West Gate Interchange in Laverton North , with ramps to and from the West Gate Freeway , Princes Freeway and Geelong Road , and heads north as a six-lane dual-carriageway until the Western Freeway /Fitzgerald Road interchange, widening to eight lanes and heading north-east, widening again to ten lanes at
960-434: A larger number of guide signs than other roads, and the signs themselves are physically larger. Guide signs are often mounted on overpasses or overhead gantries so that drivers can see where each lane goes. Exit numbers are commonly derived from the exit's distance in miles or kilometers from the start of the freeway. In some areas, there are public rest areas or service areas on freeways, as well as emergency phones on
1056-499: A legal status which limits the types of vehicles that can use a highway, as well as a road design that limits the points at which they can access it. Major arterial roads will often have partial access control , meaning that side roads will intersect the main road at grade, instead of using interchanges, but driveways may not connect directly to the main road, and drivers must use intersecting roads to access adjacent land. At arterial junctions with relatively quiet side roads, traffic

#17327811554511152-527: A milepost system but does not use milepost markers. In Europe and some other countries, motorways typically have similar characteristics such as: Two-lane freeways , often undivided, are sometimes built when traffic volumes are low or right-of-way is limited; they may be designed for easy conversion to one side of a four-lane freeway. (For example, most of the Bert T. Combs Mountain Parkway in eastern Kentucky
1248-447: A motorway is understood as a public road with dual carriageways and at least two lanes each way. All entrances and exits are signposted and all interchanges are grade separated. Central barrier or median present throughout the road. No crossing is permitted, while stopping is permitted only in an emergency. Restricted access to motor vehicles, prohibited to pedestrians, animals, pedal cycles, mopeds, agricultural vehicles. The minimum speed
1344-777: A national-level or even international-level (e.g. European E route ) system of route numbering . There are several international standards that give some definitions of words such as motorways, but there is no formal definition of the English language words such as freeway , motorway , and expressway , or of the equivalent words in other languages such as autoroute , Autobahn , autostrada , autocesta, autoput , that are accepted worldwide—in most cases these words are defined by local statute or design standards or regional international treaties. Descriptions that are widely used include: One green or blue symbol (like [REDACTED] ) appears at motorway entry in countries that follow
1440-515: A newly created site showing video simulations, maps and scheduled traffic disruptions on the freeway, for already- or nearly-completed sections. The website was revamped when Major Road Projects Victoria , established in 2019, took over management of the project. The entire length of the Freeway is being upgraded, within individual sections over a number of years. Initial work started in 2009 and work on some sections were completed in 2014. Along with
1536-573: A non-peak speed limit of 100 km/h for almost its entire length; between Greensborough Bypass and Plenty Road, the speed limit drops to 80 km/h (formerly 90 km/h before freeway works completed). The Western Ring Road between the Western Highway and the Tullamarine Freeway was previously configured with variable speed limits, which can vary between 60 km/h and 100 km/h depending upon traffic conditions. As of
1632-600: A number of patterns. The actual pattern is determined by a number of factors including local topology, traffic density, land cost, building costs, type of road, etc. In some jurisdictions feeder/distributor lanes are common, especially for cloverleaf interchanges ; in others, such as the United Kingdom, where the roundabout interchange is common, feeder/distributor lanes are seldom seen. Motorways in Europe typically differ between exits and junctions. An exit leads out of
1728-624: A park and where intersecting streets crossed over bridges. The Southern State Parkway opened in 1927, while the Long Island Motor Parkway was closed in 1937 and replaced by the Northern State Parkway (opened 1931) and the contiguous Grand Central Parkway (opened 1936). In Germany, construction of the Bonn-Cologne Autobahn began in 1929 and was opened in 1932 by Konrad Adenauer , then
1824-664: A portion of the Western Ring Road between the Hume and Western Highways was declared a National Highway in 1993 - parts of which were yet to be built at the time - allowing for direct Federal funding of its construction. Once opened, this section was signed with a National Highway M80 shield, later extended east to the junction with the Hume Freeway when the Craigieburn bypass opened in 2005, and extended south to
1920-744: A preferred route was selected in 2017, early construction began in 2020, and major construction began in late 2022, for an expected completion in 2028. Much controversy surrounds the Metropolitan Ring Road project in Melbourne in many different topics including; environmental, economical, social, private & public transportation and both positive and negative aspects are well represented for each topic by many people and groups small and large. This has led to heavy debate in all areas of society in Melbourne from political and media to general public views and conversations. The road serves various uses: Freeway A controlled-access highway
2016-457: A private venture, was the world's first limited-access roadway. It included many modern features, including banked turns , guard rails and reinforced concrete tarmac . Traffic could turn left between the parkway and connectors, crossing oncoming traffic, so it was not a controlled-access highway (or "freeway" as later defined by the federal government's Manual on Uniform Traffic Control Devices ). Modern controlled-access highways originated in

#17327811554512112-609: A reduction in deaths in a range from 20% to 50% on those sections. Speed, in Europe, is considered to be one of the main contributory factors to collisions. Some countries, such as France and Switzerland, have achieved a death reduction by a better monitoring of speed. Tools used for monitoring speed might be an increase in traffic density; improved speed enforcement and stricter regulation leading to driver license withdrawal; safety cameras; penalty point; and higher fines. Some other countries use automatic time-over-distance cameras (also known as section controls ) to manage speed. Fatigue
2208-541: A separate roadway or altogether eliminates it. In some parts of the world, notably parts of the US , frontage roads form an integral part of the freeway system. These parallel surface roads provide a transition between high-speed "through" traffic and local traffic. Frequent slip-ramps provide access between the freeway and the frontage road, which in turn provides direct access to local roads and businesses. Except on some two-lane freeways (and very rarely on wider freeways),
2304-510: A similar system of express and local lanes for a maximum width of 21 lanes on a 2-mile (3.2 km) segment between Interstate 805 and California State Route 56 . In Mississauga , Ontario, Highway 401 uses collector-express lanes for a total of 18 lanes through its intersection with Highway 403 / Highway 410 and Highway 427 . These wide freeways may use separate collector and express lanes to separate through traffic from local traffic, or special high-occupancy vehicle lanes , either as
2400-425: 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 ),
2496-411: A special restriction on the innermost lane or a separate roadway, to encourage carpooling . These HOV lanes , or roadways open to all traffic, can be reversible lanes , providing more capacity in the direction of heavy traffic, and reversing direction before traffic switches. Sometimes a collector/distributor road , a shorter version of a local lane, shifts weaving between closely spaced interchanges to
2592-400: 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; 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
2688-453: Is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway , motorway , and expressway . Other similar terms include throughway or thruway and parkway . Some of these may be limited-access highways , although this term can also refer to a class of highways with somewhat less isolation from other traffic. In countries following
2784-715: Is considered as a risk factor more specific to monotonous roads such as motorways, although such data are not monitored/recorded in many countries. According to Vinci Autoroutes , one third of accidents in French motorways are due to sleepy driving. Calder Freeway 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
2880-735: Is controlled mainly by two-way stop signs which do not impose significant interruptions on traffic using the main highway. Roundabouts are often used at busier intersections in Europe because they help minimize interruptions in flow, while traffic signals that create greater interference with traffic are still preferred in North America. There may be occasional interchanges with other major arterial roads. Examples include US 23 between SR 15 's eastern terminus and Delaware, Ohio , along with SR 15 between its eastern terminus and I-75 , US 30 , SR 29 / US 33 , and US 35 in western and central Ohio. This type of road
2976-655: Is necessary to exit onto a surface road to transfer from one freeway to another. One example in the United States (notorious for the resulting congestion) is the connection from Interstate 70 to the Pennsylvania Turnpike ( Interstate 70 and Interstate 76 ) through the town of Breezewood, Pennsylvania . Speed limits are generally higher on freeways and are occasionally nonexistent (as on much of Germany's Autobahn network). Because higher speeds reduce decision time, freeways are usually equipped with

3072-450: Is not lower than 50 km/h [31 mph] and the maximum speed is not higher than 130 km/h [81 mph] (except Germany where no speed limit is defined). Motorways are designed to carry heavy traffic at high speed with the lowest possible number of accidents. They are also designed to collect long-distance traffic from other roads, so that conflicts between long-distance traffic and local traffic are avoided. According to
3168-423: Is officially divided into two sections: Completed in stages, the freeway opened to traffic as follows: The freeway was designated Ring Road 80 when its first stage opened, quickly replaced by Metropolitan Route 80 in 1992, and extended across successive stages as they opened. With Victoria's conversion to the newer alphanumeric system in the late 1990s, this was updated to M80 in 1997 (for the sections not declared
3264-431: Is provided with separate carriageways for the two directions of traffic). Principal arterials may cross through urban areas, serving suburban movements. The traffic is characterized by high speeds and full or partial access control (interchanges or junctions controlled by traffic lights). Other roads leading to a principal arterial are connected to it through side collector roads. In this view, CARE's definition stands that
3360-407: Is sometimes called an expressway . Freeways are usually limited to motor vehicles of a minimum power or weight; signs may prohibit cyclists , pedestrians and equestrians and impose a minimum speed. It is possible for non-motorized traffic to use facilities within the same right-of-way, such as sidewalks constructed along freeway-standard bridges and multi-use paths next to freeways such as
3456-480: Is specially sign-posted as a motorway and is reserved for specific categories of road motor vehicles." Urban motorways are also included in this definition. However, the respective national definitions and the type of roads covered may present slight differences in different EU countries. The first version of modern controlled-access highways evolved during the first half of the 20th century. The Long Island Motor Parkway on Long Island , New York , opened in 1908 as
3552-545: Is the result of several changes, including infrastructure safety and road user behavior (speed or seat belt use), while other matters such as vehicle safety and mobility patterns have an impact that has not been quantified. Motorways are the safest roads by design. While accounting for more than one quarter of all kilometres driven, they contributed only 8% of the total number of European road deaths in 2006. Germany's Federal Highway Research Institute provided International Road Traffic and Accident Database (IRTAD) statistics for

Several such roads are infamous for a high rate of lethal crashes; an outcome because they were designed for short sight distances (sufficient for freeways without oncoming traffic, but insufficient for the years in service as two-lane road with oncoming traffic). An example of such a "Highway to Hell"
3744-629: The Dartford Crossing (the furthest downstream public crossing of the River Thames ) or where it was not economic to build a motorway alongside the existing road such as the former Cumberland Gap . The A1 is a good example of piece-wise upgrading to motorway standard—as of January 2013, the 639-kilometre-long (397 mi) route had five stretches of motorway (designated as A1(M)), reducing to four stretches in March 2018 with completion of

Different states of the United States have different laws. Cycling on freeways in Arizona may be prohibited only where there is an alternative route judged equal or better for cycling. Wyoming , the second least densely populated state, allows cycling on all freeways. Oregon allows bicycles except on specific urban freeways in Portland and Medford . In countries such as
4128-538: The United Kingdom new motorways require an Act of Parliament to ensure restricted right of way. Since upgrading an existing road (the "King's Highway") to a full motorway will result in extinguishing the right of access of certain groups such as pedestrians, cyclists and slow-moving traffic, many controlled access roads are not full motorways. In some cases motorways are linked by short stretches of road where alternative rights of way are not practicable such as

California , Ohio and Nevada use postmile systems in which the markers indicate mileage through the state's individual counties. However, Nevada and Ohio also use the standard milepost system concurrently with their respective postmile systems. California numbers its exits off its freeways according to

The resulting ring road will be similar to the size and scope of Sydney 's Orbital Motorway and would enable traffic to transit between the Hume and Calder Highways and Melbourne's outer east without having to cross Melbourne's inner suburbs. Once the road is built, it will run through areas that are environmentally and politically sensitive, such as Viewbank, Banyule Flats, Eltham , Templestowe or Warrandyte . A inner-city link to

Sometimes they deplete farmland, but other methods have been developed for economic, social and even environmental reasons. Full freeways are sometimes made by converting at-grade expressways or by replacing at-grade intersections with overpasses; however, in

A study has been initiated by VicRoads to supplement the Western Ring Road with an Outer Metropolitan Ring Road . Initial upgrading and widening works of the Western and Metropolitan Ring Roads was carried out between 2009 and 2014, funded by the Federal Government Auslink 2 program. VicRoads had originally produced an official "M80 Upgrade Website" with links to
5088-608: The Country Roads Board. North Western Highway was declared a State Highway on 1 July 1925, 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
5184-651: The M80 Ring Road is 25 minutes (17 minutes on the Western Ring Road and 8 minutes on the Metropolitan Ring Road) in both directions. However, peak period freeway travel times typically vary between 30 and 45 minutes in each direction, unless there are significant incidents, which can stretch travel times from 50 minutes to beyond one hour. The Ring Road project was proposed as part of the 1969 Melbourne Transportation Plan (F3, F5 & F7 Freeway corridors) and has documented in almost every edition of

Often, when there is a two-lane undivided freeway or expressway, it is converted by constructing a parallel twin corridor, and leaving a median between the two travel directions. The median-side travel lane of the old two-way corridor becomes a passing lane. Other techniques involve building a new carriageway on

On the controlled-access highway, opposing directions of travel are generally separated by a median strip or central reservation containing a traffic barrier or grass. Elimination of conflicts with other directions of traffic dramatically improves safety, while increasing traffic capacity and speed. Controlled-access highways evolved during
7008-605: 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
7104-989: The junction with the Western Freeway when the Deer Park bypass opened in 2009. It was later changed to a plain route M80 sign in 2013, for continuity with the rest of the freeway and to complement all infrastructure and signage during the 2009 to 2014 upgrade, although old signage still exists and has not yet been replaced. The passing of the Road Management Act 2004 granted the responsibility of overall management and development of Victoria's major arterial roads to VicRoads : in 2004, VicRoads re-declared Western Ring Road (Freeway #1900) from Laverton North to Hume Highway in Fawkner , and Metropolitan Ring Road (Freeway #1880) from Hume Highway in Fawkner to Greensborough Bypass in Greensborough ; however sign-posting (and VicRoads' own Declared Roads website) subsequently state
7200-769: 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 ), to 30 November 1914 (from Keilor through Diggers Rest to Gisborne , and from Woodend through Kyneton and Elphinstone to Castlemaine ), to 20 September 1915 (from Ravenswood to Bendigo); (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; and (Charlton-)Wycheproof Road between Charlton and Wycheproof
7296-469: The mayor of Cologne . The German Autobahn became the first nationwide highway system. In Canada , the first precursor with semi-controlled access was The Middle Road between Hamilton and Toronto , which featured a median divider between opposing traffic flow, as well as the nation's first cloverleaf interchange . This highway developed into the Queen Elizabeth Way , which featured
7392-400: The motorway system, whilst a junction is a crossing between motorways or a split/merge of two motorways. The motorway rules end at exits, but not at junctions. However, on some bridges, motorways, without changing appearance, temporarily end between the two exits closest to the bridge (or tunnel), and continue as dual carriageways . This is in order to give slower vehicles a possibility to use
7488-481: The name changes at the interchange with the Hume Freeway. From the upgrades beginning in 2009 onwards, it has been more common for both sections to be referred to as M80 Ring Road or simply the Ring Road, with newer signage and government websites increasingly reflecting this. An eastern extension to the Metropolitan Ring Road (the "missing link" to complete the ring road), tunnelling under Greensborough and through
7584-439: The other. Other methods involve constructing a service drive that shortens the long driveways (typically by less than 100 metres (330 ft)). An interchange or a junction is a highway layout that permits traffic from one controlled-access highway to access another and vice versa, whereas an access point is a highway layout where traffic from a distributor or local road can join a controlled-access highway. Some countries, such as
7680-477: The rate is higher than the risk on urban roads. Speeds are higher on rural roads and autobahns than urban roads, increasing the severity potential of a crash. According to ETSC, German motorways without a speed limit, but with a 130 km/h (81 mph) speed recommendation, are 25% more deadly than motorways with a speed limit. Germany also introduced some 130 km/h (81 mph) speed limits on various motorway sections that were not limited. This generated
7776-643: The rights of light , air and access to highways, but not parkways and freeways; the latter two are distinguished in that the purpose of a parkway is recreation, while the purpose of a freeway is movement. Thus, as originally conceived, a freeway is simply a strip of public land devoted to movement to which abutting property owners do not have rights of light, air or access. Freeways, by definition, have no at-grade intersections with other roads, railroads or multi-use trails . Therefore, no traffic signals are needed and through traffic on freeways does not normally need to stop at traffic signals. Some countries, such as
7872-411: The road as Calder Alternative Highway (Arterial #6200) between Ravenswood and Marong , 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 , and as Calder Freeway (Freeway #1530) between Ravenswood and Tullamarine Freeway , Airport West . The Calder Highway between
7968-432: The side of a divided highway that has a lot of private access on one side and sometimes has long driveways on the other side since an easement for widening comes into place, especially in rural areas. When a third carriageway is added, sometimes it can shift a directional carriageway by 20–60 metres (50–200 ft) (or maybe more depending on land availability) as a way to retain private access on one side that favors over
8064-695: 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 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
8160-559: The western section of the East West Link , however the project was cancelled with a change of government at the 2014 state election . In mid 2015 to early 2016, the state and federal governments had announced A$ 300 million in funding to upgrade the remaining sections along the ring road, previously allocated to the cancelled East West Link road project. Construction on the Sunshine Avenue to Calder Freeway section
8256-406: The year 2010, comparing overall fatality rates with motorway rates (regardless of traffic intensity): The German autobahn network illustrates the safety trade-offs of controlled access highways. The injury crash rate is very low on autobahns, while 22 people died per 1,000 injury crashes—although autobahns have a lower rate than the 29 deaths per 1,000 injury accidents on conventional rural roads,
8352-443: Was European route E4 from Gävle to Axmartavlan , Sweden. The high rate of crashes with severe personal injuries on that (and similar) roads did not cease until a median crash barrier was installed, transforming the fatal crashes into non-fatal crashes. Otherwise, freeways typically have at least two lanes in each direction; some busy ones can have as many as 16 or more lanes in total. In San Diego, California , Interstate 5 has
8448-587: Was again being considered by the Victorian State Government as part of a wider plan to deal with Melbourne's traffic problems. Environmental concerns about building the road through the green wedge and the disruption of communities in the area were raised. In December 2016, then Premier Daniel Andrews announced plans for extending the freeway. The project was initially estimated to cost at least $ 10 billion. In May 2016, Infrastructure Victoria released its new consultancy options assessment report,
8544-708: Was completed in September 2018. The upgrade of the Sydney Road to Edgars Road section started construction in 2020 and was completed in May 2022. The upgrade of the Plenty Road to Greensborough Highway section will be included as part of the North East Link project, which commenced construction in 2024 and will be completed in 2028. The Princes Freeway to Western Highway section is the last remaining section to be upgraded, however no funding has been allocated for planning or construction. However, minor upgrades to
8640-508: Was declared a Main Road on 28 May 1915; and Charlton-(Bridgewater-)Bendigo Road was declared a Main Road, between Bridgewater and Wedderburn to Charlton on 28 May 1915, and between Bendigo and Bridgewater on 20 September 1915. The passing of the Highways and Vehicles Act of 1924 provided for the declaration of State Highways, roads two-thirds financed by the State government through
8736-413: Was later signed National Route 79 in 1955 ; 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
8832-506: 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 where such declarations were based on the recognition that roads outside the National Highway system also provide social benefits, and were funded jointly with
8928-411: 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. Calder Highway
9024-556: Was reduced permanently from 100 km/h to 80 km/h. The 80 km/h limit applies northbound from Keilor Park Drive to Melton Highway, 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
9120-613: Was renamed Calder Highway in 1928, after William Calder , chairman of the Country Roads Board from 1913–28. 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 (already having been declared a Main Road by the Country Roads Board in 1937/38 financial year ); 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
9216-693: 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
