Plank Roads, introduced into the United States from Canada about 1837, were first constructed in New York and later in Pennsylvania, South Carolina, Illinois, Ohio, Wisconsin, and Michigan. Builders created thousands of miles of plank roads at a mileage cost of $1,000 to $2,400. To create a plank road, builders first provided good drainage by digging ditches on either side. Next they laid planks, three or four inches thick and eight feet long, at right angles to stringers, which rested lengthwise on the roadbed. Portable sawmills set up in neighboring forests prepared the planks. For a time, plank roads successfully competed with railroads, but paved roads eventually replaced them.
