# South Gippsland Highway

South Gippsland Highway is a partially divided highway connecting the south-eastern suburbs of Melbourne through the South Gippsland region of in Victoria, Australia to the town of Sale. The highway serves as a gateway from Melbourne to many attractions including Wilsons Promontory and Phillip Island as well as being an important road for farmers in Gippsland.

## Route

South Gippsland Highway commences at the intersection with Princes Highway in Dandenong, and heads in a south-eastly direction as a four-lane, dual-carriageway road towards the northern shores of Western Port Bay, through Cranbourne and Tooradin, until it reaches the interchange with Bass Highway to Phillip Island outside Lang Lang, after which it is entirely an undivided rural highway. It continues in an southeasterly direction through Nyora, Korumburra, Leongatha, Foster, Welshpool and Yarram, before heading north and eventually terminating at a roundabout with Princes Highway at Sale.

## History

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 the management, construction and care of the state's major roads from local municipalities. (Main) South Gippsland Road was declared a Main Road, from Korumburra to Leongatha, on 10 November 1913; (Main) Coast Road was declared a Main Road, from Dandenong to Lang Lang, on 1 December 1913; and Sale-Yarram Road was declared a Main Road, from Sale via Longford to Stradbroke, on 23 March 1914;
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 the Country Roads Board. South Gippsland Highway was declared a State Highway in 1933, cobbled together from roads between Dandenong and Nyora, and between Sale and Yarram (for a total of 83 miles), subsuming the original declarations of (Main) Coast Road, (Main) South Gippsland Road and Sale-Yarram Roads as Main Roads. In 1939, another section between Foster through Welshpool to Yarram was added, along the former Foster-Yarram Road. In the 1947/48 financial year, another section between Nyora via Korumburra and Leongatha to Meeniyan was added, along the former Loch-Nyora Road, Bena-Korumburra Road and Korumburra-Leongatha Roads. In the 1965/66 financial year, the last section between Meeniyan and Foster was added, completing its present-day alignment at this stage.
Conversion to dual carriageways at the western end began in 1975, initially between South Gippsland Freeway and Cranbourne; a distance of 17 km. The final link in the duplication of the highway between Dandenong and Bass Highway opened in the early 1990s between Princes Highway and Pound Road.
South Gippsland Highway was signed as State Route 180 between Dandenong and Sale on 13 December 1985, the first road in Victoria signed with a State Route, and later a concurrency with Metropolitan Route 12 between Greens Road and Pound Road through Dandenong South; with Victoria's conversion to the newer alphanumeric system in the late 1990s, this was replaced by route M420 between Lynbrook and Lang Lang, B440 between Lang Lang and Sale (which was upgraded to A440 when highway upgrades along South Gippsland Highway raised the quality of the road in 2003), and unallocated (excluding the short stretch of Metro Route 12) between Dandenong and Dandenong South. The western section of the South Gippsland Highway between the intersection of the Koo Wee Rup Bypass and the Princes Highway is gradually being renumbered to A21 and B21 following the completion of major works on Koo Wee Rup Road in 2024. The upgrade has included the rerouting of M420 to the upgraded route.
The passing of the Road Management Act 2004 through the Parliament of Victoria granted the responsibility of overall management and development of Victoria's major arterial roads to VicRoads: VicRoads re-declared the road in 2004 as South Gippsland Highway (Arterial #6580), from Dandenong South to Sale.

### Timeline of upgrades and duplication

* 1961 – Whitelaw By-pass Road: 2.5 miles just north of Korumburra completed as a 2-lane, single-carriageway road, replacing a narrow winding route 3.5 miles long consisting of portions of Bena-Korumburra and Warragul-Korumburra Roads, eliminating two railway crossings, costing A£65,000.
* 1975 – Conversion to dual carriageways at the western end began in 1975, between the South Gippsland Freeway and Cranbourne; a distance of 17 km.
* 1987 – Duplication works completed on three sections. Cranbourne to Five Ways, Tooradin to Dalmore Road, and Monomeith Road to Bass Highway.
* 1989 – 3 km of dual carriageways opened between Manks Road and Lynes Road, Tooradin in December 1989.
* 1990 – 3 km of dual carriageways opened between Lynes Road, Tooradin and Dore Road in April 1990. At this stage, ’27 km of the planned 32 km length of duplication between Cranbourne and Bass Highway has now been completed’.
* 1990/1991 – Duplication of 6 km south of Tooradin completed at a cost of $A9.9m. No exact date was given, however VicRoads Annual Reports cover the previous financial year. This completed the duplication of the highway between Cranbourne and the Bass Highway. An interesting anomaly is that the kilometre lengths quoted in this annual report and the previous annual report do not match!
* 1991/1992 – 2.8 km duplication opened between Princes Highway and Pound Road. This was the final link in the duplication of the highway from the Princes Highway to Bass Highway, Again, no exact date was given, however VicRoads Annual Reports cover the previous financial year.

### Level crossing elimination

The Gippsland railway line crossing just south of the intersection with Princes Highway in Dandenong South was removed in 3 August 2021. The contract was awarded in March 2020, with construction starting in October 2020 on a new road bridge over the rail line on an alignment just east of the original level crossing to a new intersection with Princes Highway; construction was completed and the new alignment was opened to traffic in 3 August 2021.
