I was in Wellingborough the other day and took a drive around to get some of the roads mapped. I've now got the main road that runs north/south through the town showing properly with its proper classification, I've completed the course of the A510 together with its junction of the A509 in the north, and I've got Queensway and Kingsway mapped properly, which were originally put in there with little more than guess work. Doddington Road is also now complete, and connected to its junction with Turnells Mill Lane.
It looks as though there is another user in the area doing his bit too, so hopefully before too long we'll get this hole filled in.
