King Street (Roman road)

King Street is the name of a modern road on the line of a Roman road. It runs on a straight course in eastern England, between the City of Peterborough and South Kesteven in Lincolnshire. This English name has long been applied to the part which is still in use and which lies between Ailsworth Heath, in the south and Kate's Bridge, in the north. The old road continued to Bourne thence north-westwards to join Ermine Street south of Ancaster. This part of Ermine Street is called High Dike. In the south, King Street joined Ermine Street close to the River Nene, north of Durobrivae. The whole is I.D. Margary's Roman road number 26. (Margary pp.232-234)

Archaeological work has revealed more of its length than is in use nowadays. Its course is regarded as having run from the boundary between Ailsworth and Castor, at the north-west corner of Normangate Field, just north of the River Nene (TL113980). This is where it left the Roman Ermine Street, north-west of Durobrivae in what was by the end of the 2nd century, an extensive industrial region producing tiles, metalwork and particularly, pottery.

To the south of this point, Ermine Street runs along the edge of The Fens; but to the north, lies further inland. King Street continued the course nearer the fen edge. While Ermine Street crossed the Welland near the natural ford at Stamford, King Street crosses at Lolham Bridges, which required much more engineering.
