The Big Culvert is a historic granite and bluestone arch along the Yarra Track, a major route to Melbourne through the 1800s. Built in 1870 and a major piece of infrastructure for its time, the heritage listed culvert allowed water to flow under often-flooded the road. The Yarra Track is the former name of the gold fields road from Healesville to the Woods Point and Jordan Goldfields, in Victoria, Australia. A direct route via the Yarra River and the Great Divide was discovered by Rieck in September 1862 and became known as the Yarra Track. Early in 1863, the Victorian Government decided to construct a 193-kilometre (120 mile) road along the route. Its original width varied between 4 and 6 metres (12 and 20 feet), and was designed to accommodate horse-drawn vehicles. The Track involved the climbing of the Black Spur, descent into the Acheron Valley, and then through Marysville to the Cumberland where it followed the existing route.the big culvert, yarra track, victoria, healesville, wood's point goldfields, jordan goldfields, black spur, acheron valley, cumberland valley
