From west to east, the completed sections are:
South Road Extension (2007-16) The South Road Extension runs along the Dingley Freeway route from Warrigal Road in
Moorabbin to Old Dandenong Road in
Heatherton. This was designed to remove traffic from White Street,
Mordialloc as it was experiencing heavy-local traffic congestion, as a result of the most direct route linking the
Mornington Peninsula Freeway with the
Nepean Highway, along with Boundary and Wells Road. The 1 km extension commenced construction in September 2006 and was completed by the end of 2007, at a cost of $9.3 million for the South Road extension alone, but cost $24.5 million when combined with the associated projects. The works involved constructing a two lane road to bypass a stretch of Old Dandenong Road which travelled through a residential area to Warrigal Road. A bicycle path was also constructed along the length of the extension. The extension also involved improvements to Old Dandenong Road and surrounding intersections as well as permanently blocking access to Old Dandenong Road north of the extension. The extension has a speed limit of 70 km/h. Despite the road having successfully removed traffic from Old Dandenong Road (between Warrigal Road and the current South Road connection) it had also created a major bottleneck at the intersection of Kingston and Old Dandenong Road, particularly during peak hour. The project was later duplicated and overwritten by the Dingley Bypass project below, which cut Old Dandenong Road in half in its vicinity.
Dingley Bypass The state government announced in May 2012 they will commit $156 million for the construction of the Dingley Bypass, which will be a new 6.4 km dual carriageway link between Warrigal Road and Westall Road in Melbourne's South-Eastern suburbs. Construction of the Dingley Bypass began in 2014 and was completed in March 2016, 5 months ahead of schedule. The $156 Million, 6.4 kilometre Dingley Bypass was completed five months ahead of schedule and was opened on 11 March 2016 by Minister for Roads, Luke Donnellan. A divided highway with 3 lanes in each direction, it is expected to carry 35,000 vehicles each day. A new 5.2 kilometre bike path also runs beside the Bypass and extends from the existing bike path at Old Dandenong Road and provides vital links to Victoria's greater bicycle network. In November 2018 leading up to the
state election, the
Victorian Liberal Party proposed removing all traffic lights on the Dingley Bypass to create a Dingley Freeway. This was expected to cost $600 million.
Springvale Road to Perry Road The Springvale Road - Perry Road section of the bypass connects
Westall Road to the already-open Perry Road to South Gippsland Highway section at Perry Road, creating an arterial standard highway, with traffic light controlled intersections and an overpass at Cheltenham Road. The new section of road, which commenced construction in 2011, is expected to carry between 30,000 and 40,000 vehicles per day as well as a shared path being constructed alongside, linking to existing shared paths which already run along the built sections of the arterial. The construction of this section (at a cost of $74.6 million) was brought forward to commence in 2010 as part of the "Nation Building" initiatives in the 2009 Victorian State Budget. The project was completed early and under budget (previously estimated to cost $80 million) to traffic on 20 December 2012.
Perry Road to South Gippsland Highway The bypass commenced construction in late 2005 between Perry Road and South Gippsland Highway as part of the
EastLink project, with the $65 million works involving the creation of a four lane divided road with traffic light controlled access at roads which run north–south along the constructed route. The 4.8 km bypass also included an overpass of the
Cranbourne railway line as well as a
diamond interchange with EastLink. The entire bypass has an 80 km/h speed limit. The project was completed and opened to traffic on 9 December 2007. == Future sections ==
