South Road, Melbourne

South Road begins at the intersection of Warrigal Road and Dingley Bypass in Moorabbin and ends at Beach Road in Brighton. It travels west as a 6-lane dual carriageway with intersections at Chesterville Road, East Boundary Road, Jasper Road and Nepean Highway. It then reduces to four lanes after Nepean Highway and then intersects at Bluff Road, Hampton Street and New Street before ending at Beach Road in Brighton next to Brighton Beach railway station.

The South Road Extension ran 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 kilometres per hour (43 mph).

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, which cut Old Dandenong Road in half in its vicinity.
