How about this one in your part of the world - B1098 half way between Chatteris and Outwell. The pic is not too clear, but the road to the right goes under the railway with a 7ft clearance
. It is meant for cars only when the railway crossing gates are closed on the higher road. Fun to go roaring through this underpass but, on a first approach, even in a car you think you might not make it!
