The covered wagon was long the dominant form of transport in pre-industrial America. With roots in the heavy Conestoga wagon developed for the rough, undeveloped roads and paths of the colonial East, the covered wagon spread west with American migration. The Conestoga wagon was far too heavy for westward expansion. Typical farm wagons were merely covered for westward expansion. Heavily relied upon along such travel routes as the Great Wagon Road and the Santa Fe and Oregon Trails, covered wagons carried settlers seeking land, gold, and new futures ever further west.
