Why isn't there an M7?
(James O'Brien: How did this motoring question sneak through?!)
** Definitive **
Name: Ryan, Hackney
Answer: A motorway just relates to the A road that it's relieving pressure from. The reason there is no M7 is that the A7, which runs from Carlisle to Edinburgh has no need for a motorway to relieve it.
Name: Peter, Streatham
Qualification: No enough of one…
Answer: There is no M7. The way the roads are organised, the numbers were set up centred on London. The M1 and A1 start in London and head north. The M2 heads east, the 3s south, the 4s west.
(James O'Brien: But why isn't there an M7. You haven't actually answered that.)
