late 18th and the early 19th centuries. Highway 2 from Toronto eastwards was a plank road in the 19th century that was later paved. In 1833 Scarborough-Markham Plank Road was authorized to build a road from Danforth Road to Highway 7 to Ringwood and east on Stouffville Road to Main Street Stouffville. Part of this Plank roads are used exclusively in the Canadian fishing outport of Harrington Harbour, Quebec because the town is built directly over a hilly, rocky shore. ATVs are the only mode of transportation there. In Australia In Perth, Western Australia, plank roads were important in the early growth of the agricultural and outer urban areas because of the distances imposed by swamps and the relatively-infertile soil. As it cost £2,000/km to construct roads by conventional means, the local councils, known as road boards, were experimenting with cheaper approaches to road building. A method called Jandakot Corduroy had been developed at Jandakot south-east of Perth: a jarrah tramway lay upon sleepers, bounded by two strips of jarrah planks for cart and carriage wheels. The gap was filled with limestone rubble to be used by horses. This reduced the cost of road building by up to 85% after its widespread introduction in 1908. However, increased traffic and suburban development rendered the routes unsatisfactory over time, and by the 1950s, they had been replaced with bitumen surfaced roads.
