WRONG The Highways Development Survey drawn up by engineer Sir Charles Bressey and his consultant Sir Edwin Lutyens provided the first coherent proposal in 1937 for an orbital road round Greater London, at a radial distance of 18 to 20 miles from Charing Cross. World War II put paid to their grand plans, but the route they devised for the South Orbital section in particular is pretty much followed by the M25 today.

WRONG North Ockendon a scattered farming community with labourers’ cottages at its core on Church Lane is the only settlement outside the M25, but within Greater London. Curiously impoverished South Ockendon is not subject to ULEZ.

CORRECT The M25 passes through all six of the so-called Home Counties: Kent, Surrey, Berkshire, Buckinghamshire, Hertfordshire and Essex. Most book and website references on the layout of the M25 will tell you that the motorway passes through only five counties, failing as they do to recognise the very short passage across the little bit of Berkshire that manages to infiltrate the circumference just south of J13.

CORRECT In 1991 Chris and Sue Glazier won a mystery prize in a local radio competition for couples intent on marriage. The prize was a prepaid wedding, which they were told the night before the ceremony would involve spending their wedding night travelling at 50 mph with their guests being invited to come along for the ride. The wedding the next day at Thurrock Services was followed by a coach trip round the M25, the coach had at least been fitted out with a four-poster bed, and the organisers were sufficiently discreet to drop the guests off after the first of three circuits.

CORRECT Motorway Permanent is used on the regular white-on-blue and Motorway Temporary for the black-on-yellow roadwork signs. Designed in 1958 by British graphic designers Jock Kinneir and Margaret Calvert, who also designed many of the pictograms that we are so familiar with, such as the instantly recognisable Men At Work. The designs are so good that there has been no need to change them for over 60 years.

WRONG This humble junction has a real claim to fame, because it possesses the longest motorway slip road in the country, climbing up Reigate Hill for 1.5 miles, and perhaps surprisingly, the A217 that crosses over it reaches the Fulham Road.

WRONG At a carefully choreographed ceremony somewhere between J22 and J23, and after a 58-page illustrated brochure to commemorate the opening had been produced, nothing was left to chance, right down to a practice run of the removal of a single cone by an employee of similar build to the prime minister the day before, on 29 October 1986 Thatcher picked up a cone in each hand and symbolically marched them off to the side of the road. The handbag didn’t budge an inch.

CORRECT The Prime Meridian Line is about 1.5 miles west of Clacket Lane Services, when we excitingly travel through time, or at least through the point at which the world’s time begins, returning about halfway between J25 and J26, we re-enter the Eastern Hemisphere of planet earth. Immediately after we do so we will rather appropriately cross from Hertfordshire into Essex, the county of the East Saxons.

WRONG During the two years it took to construct the tunnel between J26 and J27 by cut-and-cover, the Epping Foresters Cricket Club agreed to play as a wandering club on the understanding that their pitch and pavilion would be reinstated on the same common land above the tunnel once its cutting had been covered over, and that duly happened. It is the English way, after all.
