What does M stand for in roads?
What does M stand for in roads? M routes are primary traffic routes, called motorways in some states. These are typically dual carriageway, freeway-standard highways, but may also be used for rural roads that are nearly at freeway-standard, or at least are dual carriageways.
Why is the M5 so fast?
The M5 CS features a V8 engine that is fitted with optimised turbochargers and a maximum injection pressure of 350 bar. This allows for quicker injection times, which improves the atomisation of fuel. Improvements have also been made to lubrication and cooling.
Why is there no M10?
When the M1 was upgraded to four lanes between the M25 and Luton, the M10 was killed off. Collector-distributor roads were built alongside the M1, and the A414 was routed on what was the M10, up the parallel carriageways alongside the M1 and off to join the next section of A414 at junction 8.
Why is there no M7?
There is no M7 because there has never been a need to replace the A7 with a motorway. There was an idea in the 1990s to build a new toll road linking Edinburgh and the A74 (M), along the lines of the A702, and the idea was floated that this could take the M7 number.
