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 [REF].
