Hi Fortunato, Dual Carriageway - H-hm well. A rough translation would be two lanes of traffic going in approximately one direction and another two lanes of traffic going in approximately the opposite direction. These four lanes of traffic are often (but not always) seperated by a central reservation. I'm not in London area otherwise I'd join you, but I hope you and your good lady have a fantastic time.

All the best

Nynia
