Watford Gap

Topographically the gap is a pass (small cleft) caused by a tectonic plate shift (according to Roger Latham), between east and west hill ranges. A tributary of the River Nene rises at Watford and flows east to the Wash, whereas at Kilsby a tributary of the River Leam /lɛm/ rises and flows west.[n 1]

Foot-strut split isogloss

In linguistics the Watford Gap has become oft-quoted as where England experiences its division of north and south dialects. Specifically it is close to the north/south isogloss of the three key hallmarks of Northern English and Southern English: foot–strut split, bad-lad split and the Bath vowel, however traditionally follows most East Midlands accents.

Making use of the above linguistic divide, authors, journalists[1][2] and social commentators have written and spoken of a North/South divide between Northern England and Southern England (although, in this context, the reference is sometimes assumed to be to the town of Watford in Hertfordshire, some 61 miles / 98 km to the southeast by road).

There is a well known expression, "North of Watford", which is used to mean the north of England, especially a place remote from London.[3] This is often taken to mean "North of Watford Gap" because of the Watford Gap services being a main stopping point on the M1 motorway.[4] However, the original expression was already in use many years before the Watford Gap Service Station or M1 opened in 1959.[5][6][7] It is unknown whether the original expression referred to Watford, Northamptonshire, or the much larger Watford town in Hertfordshire, which was the last urban stop on the main railway line out of London to the north of England. There is evidence to support the latter, as the phrase "North of Watford Junction" was used with similar meaning in the past, referring to Watford Junction railway station at Watford, Hertfordshire.[8][9][10]

Historically, this was a junction of the West Midlands to London or East Anglia stagecoach routes across England. Its coaching inn, the Watford Gap, plied the passing trade of the area.

The pub, as well as the route from Cambridge to Coventry, is mentioned as early as 1769.[11] This route ran through Northampton, Duston, Harlestone, past Althorp Park, Brington, Long Buckby, Watford, Watford Gap itself—the map indicating that the coaching inn was on the west side of Watling Street, and then into Kilsby. The route from Watford Gap to Kilsby is now part of the diverted A5 road following construction of the M1 motorway.

The location of the Watford Gap coaching inn is the subject of confusion, with a location on the east side of the Grand Junction Canal (within the confines of the modern service station) being the most frequently cited, near the disused Welton railway station. There is no mention of a Watford Gap pub or any other pub at the suggested location on the 1889 or 1927 or 1952 Ordnance Survey maps of Northamptonshire. The nearest pub was the now-closed Stag's Head Inn in Station Road, Watford. The original location is further north on Watling Street and is shown on the 1889, 1927 and 1952 maps (52°19′26.33″N 1°8′32.58″W).

The canal-side building still stands but, as of 2000, has closed for business and needs renovation. The earlier Watford Gap Inn is also still standing and is in good repair and generally unaltered, with the stabling yards and main structures used as farm buildings. It can be easily viewed from the road: there is a parking lay-by on the southbound side of Watling Street.
