 This ancient route predates the Norman Conquest and remained the main east-west route through the county until the 17th century.It can be seen quiet clearly on William Faden’s map of Norfolk, which was surveyed between 1790 and 1794.This map, the first large-scale map (at one inch to the mile) of the whole county, is a record of the landscape and transport system of the county of Norfolk in late 18th century and shows that despite the Parliamentary Enclosure of the early 19th century the route has changed very little.
