Over the years almost every A-road junction in the countryside has been replaced with a roundabout. Here's a list of the rural A-roads that still meet at crossroads. Please add any others you know of. If any of these are replaced with a roundabout, please add the date of the change.

Notes
1. I'm defining a crossroads as a junction that one can leave by (at least) four exits. It must be possible to cross the junction in a single movement (ie. no stagger, no double lights) from two non-opposite directions.
2. I'm defining "rural" as not within, or on the edge of, the urban (built-up) part of a town. A town is a settlement which had/has UD, MB, CB, LB or MBC status.
