Lidar Image - Full Route
Coltishall Bridge was obviously a critical crossing point of the River Bure and the route certainly targets it. The existence of the Roman camp at Horstead, presumably watching that crossing place, reinforces this must have been a strategic location.

Quite secure this stretch with several clues all the way to St James.

Dark Lane 1
Definitely an old road and one almost certainly 2000 years old! The road itself is now worn down to almost a hollow-way but the outsides are still built up - see below. |

Dark Lane 2
I had driven past this feature many times and wondered - it looks like a Roman road. It all makes perfect sense now we now the Roman had a road to a harbour at Hickling. This is the agger of Dark Lane from the south side. |

Tramlines, ie the Roman road ditches, are often a great clue to Roman roads when the agger has been ploughed away. Only the ditches survive. They continue the alignment of Dark Lane and onto the modern lane to Crowgate Street. Quite a significant name that with two road references within it - gate and street.

The target was obviously the crossing of the River Bure at Coltishall. The undulations here resulted in some adaptation to the line.

Agger - St James
After crossing a stream in St James the road agger shows in two fields in the Lidar image - see above. The first field is tree covered but the second is more open and the agger can be made out in this view. Note also the swell where the far fence passes over the agger. A very common feature of Roman roads.

Contour Map - Coltishall - Horstead
Coltishall has long been an important bridging point for the Bure and the nearby Roman camp shows it was a crucial crossing point for the Romans too. On the Horstead side of the bridge then the road runs on a built up causeway to the Recruiting Sergeant public house. This would be expected as this is low lying marshland.

Lidar Image - Horstead Roman Camp
The camp really only shows up on aerial photographs - just sections of the ditch around survive. There are some indications the road would have passed the camp's south-east corner. The modern road goes through the middle of the camp. This is currently the only known Roman camp in East Anglia. Clearly an important place.

Contour Map - Horstead to Spixworth Bridge
So far the clues to the road have been sufficient to work out the route but from here onwards then the evidence becomes very sketchy. The modern road appears to overlay the Roman route in several places. The route shown is therefore the likeliest course and fits well with the contours. Roman Road 3e, Brampton to Caistor, would have been joined just to the north of Spixworth Bridge. A sensible place for this junction as the routes would then share a single bridge. No need to build two.
