These are fun when driving in fog, or in a hurry across the Somerset Levels, as some have discovered to their loss, especially when rabbits appear in front of you between an 8 foot wall and the ditch.

Intersections are often obtuse angular and modelling the flow hydraulics mainly a matter of retaining overall site standing by Rivers and Drainage Boards, although some strong streams can occur in winter floods.
