The A1231(M) was planned as the western end of the new A1231 into Sunderland from the west. Growth of the New Town of Washington forced these plans to change and that road was plugged into the A1 further north instead. The road in Vigo was renumbered A195 and A195(M), which is also secretly numbered.
