Western Port Highway (formerly Dandenong-Hastings Road) is a highway in Victoria, Australia, linking the south-eastern fringe of suburban Melbourne to the western coast of Western Port Bay, after which the highway is named, at the Port of Hastings nearly 30 km to the south. It runs from the end of the South Gippsland Freeway at Lynbrook firstly as a dual carriageway and later as an undivided road to Frankston-Flinders Road at Hastings.


The Western Port Highway was originally a single carriageway road called Lyndhurst Road in the 1960s, it has been progressively upgraded to a divided highway between the South Gippsland Freeway and Cranbourne-Frankston Road during the 1990s, as dramatically-increasing freight traffic volumes to and from Hastings necessitated major upgrades.

VicRoads is currently planning an upgrade to freeway standard between South Gippsland Freeway and about 1.2 km south of Cranbourne-Frankston Road with full grade-separated interchanges at Glasscocks Road, Thompson Rd, Hall Road and Cranbourne-Frankston Road.[2]


The highway begins at Lyndhurst interchange, where the South Gippsland Highway and the alignment of the South Gippsland Freeway meet, outside Lynbrook; Western Port Highway is linked directly to the southern end of the South Gippsland Freeway by an overpass over the South Gippsland Highway. From the interchange, Western Port Highway runs south as a two-lane (each way), dual carriageway, overpassing the Cranbourne railway line, passing through a set of traffic lights at Moreton Bay Boulevard, and passing through roundabouts at Glasscocks Road, and Thompsons Road; between here and Lyndhurst interchange the highway is designated route M780. The highway runs onwards further south through roundabout intersections with Hall Road, Ballarto Road and Cranbourne-Frankston Road. The road continues south to North Road, as a dual carriageway but designated as route A780, before reverting to a dual-lane single carriageway road to Hastings. It continues further south with a roundabout at Baxter-Tooradin Road and finally ending at an intersection with Frankston-Flinders Road, 2 km north of Hastings.

For most of the route the speed limit is 100 kilometres per hour (62 mph), with shorter sections of 90 kilometres per hour (56 mph) and 80 kilometres per hour (50 mph).
