Term: plank road
Definition: a road typically constructed of wood planks two inches thick and eight feet long, which were nailed to four-inch-square stringers at a 90-degree angle. Tolls were charged for traveling on the roads, usually one-cent per mile for single animal vehicles and an additional half-cent per animal hauling a vehicle. A typical drive from Milwaukee to Green Bay with a team would cost $3.78. View more information elsewhere at wisconsinhistory.org.
