CORDUROY ROAD. A road or causeway constructed with logs laid together over swamps or marshy places. When properly finished earth is thrown between them by which the road is made smooth; but in newly settled parts of the United States they are often left uncovered, and hence are extremely rough and bad to pass over with a carriage. Sometimes they extend many miles. They derive their name from their resemblance to a species of ribbed velvet, called corduroy. [Bartlett]
