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 quite 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. Much of the route on the map is highlighted in a pale pink, which marks it out as an important artery of the time. Part of the roads route lies directly on the line of a
Roman road between a point west of
North Elmham for the distance of to where the road reaches the village of
Bawdeswell. The route is dissected by several Roman roads, including the
Peddars Way in the
North West of Norfolk. Road schemes at Bawdeswell, Aylsham and North Walsham have created interruptions to the original route, although the vast majority of it remains intact. ==Coaching route==
