The chief road officer was responsible for the construction and upkeep of the streets, roads and bridges, and for establishing building lines in the towns. In the early decades of the colony, the St. Lawrence and its tributaries were the principal means of communication. After completion of the chemin du roi [the King's road] in 1737, the Québec-Montréal trip could be made in four days.
