Nepean Highway is a major highway in Victoria, running south from St Kilda Junction in inner-southern Melbourne to Portsea, tracing close to the eastern shore of Port Phillip for the majority of its length. It is the primary road route from central Melbourne through Melbourne's southern suburbs. This name covers a few consecutive roads and is not widely known to most drivers except for its central section, as the entire allocation is still best known by the names of its constituent parts: St Kilda Road, Brighton Road and Nepean Highway proper, and Point Nepean Road. This article will deal with the entire length of the corridor for sake of completion, as well to avoid confusion between declarations. Route St Kilda Junction to Mornington Historically starting at the Melbourne CBD at Princes Bridge as St Kilda Road and heading south through the Melbourne Arts Precinct, today Nepean Highway is declared to commence at St Kilda Junction as St Kilda Road and heads in a southerly direction until it reaches the intersection with Carlisle Street (prior to the widening in the late 1960s this section was formerly known as High Street), where it changes name to Brighton Road and heads in a south-easterly direction until it reaches the intersection with Glen Huntly Road in Elsternwick, where it changes name again to become Nepean Highway proper. Tram route 67 runs down the middle of the highway until it turns into Glen Huntly Road. In 1984 conversion of the seven kilometre section between Cochrane Street, Elsternwick and South Road, Moorabbin to a dual carriageway was completed. At Glen Huntly Road, the speed limit increases to 80 km/h and the road widens to become an eight-lane dual carriageway. It is reduced to six lanes at Moorabbin, passing through Cheltenham and Mentone, and then to the 60 km/h or 70 km/h four-lane single carriageway after the roundabouts at Mordialloc. The highway then travels virtually along the foreshore of Port Phillip Bay to Frankston, with several stretches of dual carriageway, and then up Olivers Hill, from which there are good views across Frankston and the bay. Mornington Peninsula In the late 1960s a bypass road was constructed in the suburb of Mount Eliza. Previously the highway travelled through the main shopping village: this section is now known as Mount Eliza Way. After passing through Mount Martha, the highway runs parallel to the Mornington Peninsula Freeway, before turning
