<Li> Highways in Victoria </Li> <P> The Great Ocean Road is an Australian National Heritage listed 243 kilometres (151 mi) stretch of road along the south - eastern coast of Australia between the Victorian cities of Torquay and Allansford .

Winding through varying terrain along the coast and providing access to several prominent landmarks, including the Twelve Apostles limestone stack formations, the road is an important tourist attraction in the region . </P> <P> The Great Ocean Road starts at Torquay and travels 244 kilometres westward to finish at Allansford near Warrnambool, the largest city along the road . The road is two lane (one in each direction), and is covered by a speed limit changing between 50 kilometres per hour and 100 kilometres per hour . </P> <P> The road is considered a tourist attraction in the area, in which much of the road hugs coastline affectionately known as the Surf Coast between Torquay and Cape Otway and the Shipwreck Coast further west of Cape Otway, providing visibility of Bass Strait and the Southern Ocean . The road traverses rainforests, as well as beaches and cliffs composed of limestone and sandstone, which is susceptible to erosion . The road travels via Anglesea, Lorne, Apollo Bay, and Port Campbell, the latter being notable for its natural limestone and sandstone rock formations including Loch Ard Gorge, The Grotto, London Arch (formerly London Bridge) and The Twelve Apostles . At the stretch of the Great Ocean Road nearer to Geelong, the road meanders along the coast, with tall, almost - vertical cliffs on the other side of it . Road signs put up along the road warn motorists of possible rockfalls, which have occurred before . </P>
