Grantham isn’t great for exit either. I ended up spending over half an hour trying to get OUT of the town, towards Melton Mowbray, in a car because of inadequate direction signs which was not helped by roadworks shutting two town centre roads. That was after the struggle to get into the town from the A52 at a new roundabout for the same reason.
you could make a living at it… there is another one on the way to edenbridge that could do with changing.
