Originally conceived as the London to Yorkshire Motorway, the M1 was the first inter-urban motorway in the United Kingdom. It was, however, not the first motorway as the M6 Preston Bypass holds that honour. The route of the M1 has evolved over the years, initially through Northamptonshire, Buckinghamshire, Bedfordshire and Hertfordshire and rapidly extended south and north to create a motorway alternative to the A1 between Edgware and Doncaster by 1967, extending further north to Leeds with the opening of the Tinsley Viaduct by 1968 and south to the A406 North Circular Road by 1977. Further work completed in 1999 saw the M1 extended to meet the A1(M) near Garforth.
The M1 forms the backbone of the English motorway network, with key connections in the south with the M25 London Orbital, in the Midlands with the M6 and in the north with the M62 and A1(M), along with other less important motorways along the way. Because some parts of the M1 are more important than others, some sections carry significant varying volumes of traffic with the predominant D3M design of the original route has some sections reduced to D2M (at J19 & J34 for example) and significant sections upgraded to D4M in more recent years.

A 1km long viaduct, with a troubled past and uncertain future, designed by Freeman Fox and Partners, an iconic steel monument to the valley it passes over.
Infamous perhaps for being one of the worst thought-out junctions on the trunk road network. The key route between the major east coast ports and the industrial heart of England, has to squeeze under a bridge which was formerly used by an unclassified back road.
A cheap solution at first, gradually becoming a big headache, eased by the spending of private sector money and given a stay of execution with a few traffic signals. Lofthouse Interchange to be fair works quite well, sadly, the M1 to the south and north suffers congestion each evening due to the close proximity of J41 and the weaving of traffic getting on at J42 to head south and the traffic from the north wanting to exit at J41.
Most junctions on the M1 have names as well as junction numbers, these names sometimes come from the construction name, some are more popular names developed after the motorway opened.
