During a recent visit to Silloth, I mapped most of the town. There are still several roads remaining round the edges, though, as my time was limited.
Also mapped a few roads in Maryport but much more work is needed.
I have also done quite a lot of NPE tracing in the area between Maryport, Silloth and Carlisle. I've been marking roads as highway=road. There's quite a bit more tracing work to do to join up with the area to the south of Cockermouth which has already been done.
