What remains of the former B5312 Finkle Street
The B5312 was originally allocated around 1924 to Finkle Street and Corporation Road in Carlisle, as a shortcut between the A595 and the A7.
Aside from the B5307, it was the northernmost road in the 5 zone, and the only one to join to a road in the 7 zone. Being just slightly south of the River Eden gives evidence to the theory that the river was the 5 / 7 zone boundary out to the Solway Firth.
By the 1940s, the road was important enough to be upgraded to Class I status and became a spur of the A595. The road has since been part upgraded, part bypassed by the A595 Castle Way.
