The Roman Road from Carlisle to Birrens, Margary 7f

Formerly a little bit of doubt over the location of parts of this route but Lidar has confirmed that Margary correctly surmised that, after heading due north from Carlisle, the road crossed the Esk at the Roost ford.

This road is clearly linked with the road to Netherby (Margary 868) and it could be argued that this is actually a branch off that road.

We will trace this road as far as the Scottish Border at Springfield, Gretna.


 

Carlisle Road Map

Our road, after crossing the River Eden, heads almost due north initially along the A7, Scotland Road but where the latter swerves off to the west at Kingstown, the Roman road carries straight on.

Map derived from Hogg, McCarthy and Breeze. Hogg researched where the bridge was likely to be, McCarthy produced the definitive text on Roman Carlisle and David Breeze produced a map!

Lidar Image

The first evidence visible in the Lidar data is west of Houghton either side of the M6 where the housing development ends. The agger is particularly clear where the road merges into the A7, just south of Blackford.

Lidar Image - Sandysike Junction

Here the the road to Birrens probably leaves the road Netherby. Across the River Lyne, river movements over the years seem to have destroyed any remains. Sandysike Lane (assumed name) almost certainly marks the junction - see below.

Junction

Lane at Sandysike Mill

The lane is very straight but is not built up. It does however, align with the Roost Ford, so on balance it would seem to be the best candidate for the Roman road to the ford.

End of Sandysike Lane

Here the modern road heads off to the right but the Roost ford is just over a kilometre straight on.

3d Lidar Image - Roost Ford

The Roman agger has amazingly survived and is clearly visible across the munitions factory. Who would have though it could have survived here? Margary was sure it would have been destroyed.

Lidar Image - Roost Ford to Springfield

The Roman agger is visible just about all the way the way to Springfield.

Beyond, Springfield (Gretna), the B7076 modern road marks the course onwards to Birrens.
