As Jersey is not part of the GB mainland, there was no basemap uploaded for Jersey. The road network is growing slowly. Currently most major roads are done, I am currently tidying up what there is at the moment to make sure it routes correctly.
I have gone through the current map and named all of the "no name" roads and fixed routing problems that I have seen.
I am currently working through easch parish doing the towns / villages and then tidying up the in-between roads.
I visit often so if you have any requests, PM me in the forum (richardjeeves) or post a map request/error and I will take a look at it (I look at requests daily). Include as much info as you can.
