A plank road is a road composed of wooden planks or puncheon logs. Plank roads were commonly found in the Canadian province of Ontario as well as the Northeast and Midwest of the United States in the first half of the 19th century. They were often built by turnpike companies. Origins The Wittmoor bog trackway is the name given to each of two historic plank roads or boardwalks, trackway No. I being discovered in 1898 and trackway No. II in 1904 in the Wittmoor bog in northern Hamburg, Germany. The trackways date to the 4th and 7th century AD, both linked the eastern and western shores of the formerly inaccessible, swampy bog. A part of the older trackway No. II dating to the period of the Roman Empire is on display at the permanent exhibition of the Archaeological Museum Hamburg in Harburg, Hamburg. This type of plank road is known to have been used as early as 4,000 BC with, for example, the Post Track found in the Somerset levels near Glastonbury, England. This type of road was also constructed in Roman times. In North America From the mid-1840s and to mid 1850s, the United States experienced the Plank Road Boom and a subsequent bust. The first plank road in the US was built in North Syracuse, New York, to transport salt and other goods; it appears to have copied earlier roads in Canada, which had copied Russian ones. The plank road boom, like many other early technologies, promised to transform the way people lived and worked and led to permissive changes in legislation seeking to spur development, speculative investment by private individuals, etc. Ultimately, the technology failed to live up to its promise, and millions of dollars in investments evaporated almost overnight. Three plank roads, the Hackensack, the Paterson, and the Newark, were major arteries in northern New Jersey. The roads travelled over the New Jersey Meadowlands, connecting the cities for which they were named to the Hudson River waterfront. U.S. Route 1 in Virginia follows the Boydton Plank Road from Petersburg southwards to just north of the North Carolina line. On the U.S. West Coast the Canyon Road of Portland, Oregon was another important but short artery and was built between 1851 and 1856. Kingston Road (Toronto) (Governor's Road) and Danforth Avenue, in Toronto, were plank roads built by the Don and Danforth Plank Road Company in the
