Hardly anybody loves it, many of us loathe it, but the M25 has become a part of the daily lives of thousands of motorists.

The first section of the 117-mile London Orbital Motorway had opened 11 years previously but on October 29, 1986 – 37 years ago yesterday – the road was officially opened by Margaret Thatcher.

A Watford Observer photographer joined dozens of media colleagues between junctions 22 and 23, a short distance from Watford, where the then Prime Minister was joined by Secretary of State for Transport John Moore and chairman of Balfour Beatty Don Holland for the opening ceremony.

“Now some people are saying that the road is too small, even that it's a disaster,” Mrs Thatcher said. “I must say I can't stand those who carp and criticise when they ought to be congratulating Britain on a magnificent achievement and beating the drum for Britain all over the world.”

Many people would argue the critics of the scheme have been proved correct, but there can be no disputing the impact the M25 has had on the lives of those of us who live near to it or use it on a regular basis.
