How are motorways numbered in UK?
The motorway numbering scheme is based on the numbering scheme of the A roads that preceded them. You may have noticed that many Motorways run close or parallel to A roads with the same number. The first motorway, the M40, was built from London to Oxford along a similar route to the A40.
How UK roads are numbered?
The basic idea is that most roads in England and Wales begin with numbers 1, 2, 3, 4, 5 and 6, with London as the hub, and most roads in Scotland begin with numbers 7, 8 and 9, with Edinburgh as the hub. There are three basic types of numbered road: motorways (beginning with an M), A-roads and B-roads.
Why is there no M7 in the UK?
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. The way the roads are organised, the numbers were set up centred on London.
What does the A stand for in a roads?

It runs from Catthorpe (junction 19 on the M1) to the Scottish Border. The M62 is the highest motorway in the UK.
How are motorway junctions numbered?
Junctions are normally numbered consecutively. Gaps in the sequence are sometimes deliberately left to allow for planned future junctions. New junctions not provided for in the original numbering scheme can be indicated by numbers with appended letters A, B etc.
How do roads get numbered?
Interstate Route Numbering Major Interstate routes are designated by one- or two-digit numbers. Routes with odd numbers run north and south, while even numbered run east and west. For north-south routes, the lowest numbers begin in the west, while the lowest numbered east-west routes are in the south.
What does the M stand for on British roads?
There are three basic types of numbered road: motorways (beginning with an M), A-roads and B-roads. There are also sections of A-road, such as the A1(M), which have motorway restrictions on them, although these do not need to have numbered junctions (which motorways do).
What does the M stand for in motorways?
M-class motorways are labelled in the form Mx, as a higher grade of motorway, and A(M) roads are labelled in the form Ax(M), where x is the designation of the road, dependent on the zone. For example, the M25 is the London Orbital Motorway, and the A1(M) is the upgraded A1 dual carriageway.

What is the smallest motorway in the UK?
the A308

What motorway numbers are missing from the UK?
For A roads and motorways, numbers beginning 7, 8 and 9 are allocated to Scotland (rather than centred on London). I believe the only major single integer motorway number missing is the M7. Simon Gilman, Edmonton, London, UK. There is an M7 – it is in Scotland.
Should motorways be given their own numbering scheme?
Generally, the plan for motorways to be given their own numbering scheme gathered pace, and the only reference to a motorway being given a number as if it was part of the all-purpose scheme (as above) is a reference to the London to Yorkshire Motorway being temporarily assigned the number of A50.
How are a roads numbered in England?
As others have said, A roads are numbered by 9 zones, notionally bounded by the A1 to A9. In England and Wales, motorways are also numbered by zones, but these are not the same as the A road zones. Whilst some motorways run alongside an A road with the same number, this is by no means universal.
What are the motorway numbers between the M1 and m2?
Motorways were later developments, and follow the same pattern as the trunk roads, so between the M1 and M2 you will find the M10 and M11. For A roads and motorways, numbers beginning 7, 8 and 9 are allocated to Scotland (rather than centred on London).
