From Brampton Old Church, the road crosses the River Irthing and continues southwest through Irthington and passes through what is now the site of Carlisle Airport, just to the north of the main runway. The curving corner of an associated marching camp can be made out from the air on the south edge of the runway near its western end, and can be seen on Google Earth. The Stanegate then continued through a large cutting in High Crosby, where a small fort has been postulated, based on marching distances, but has not yet been found. The Stanegate then crossed the River Eden near the cricket ground in modern Carlisle and eventually reached the fort of Luguvalium (Carlisle) on the site of Carlisle Castle, from Brampton Old Church and from Corstopitum. It has been suggested that the road may have carried on west for a further to the Roman fort at Kirkbride overlooking Moricambe Bay, an inlet of the Solway Firth. A large camp of was found there but the evidence for a road is insufficient.
