Watford Gap Services (M1 J16–J17)
Watford Gap sits on the M1 between Junction 16 and Junction 17 in Northamptonshire. It is run by Roadchef, and it opened on 2 November 1959 — the day the M1 opened.
The name is a real place, and it is not the Watford you are thinking of
The Watford Gap is a genuine geological pass, and within a corridor about 400 metres wide it carries the Roman Watling Street, the Grand Union Canal, the West Coast Main Line and the M1. The phrase “north of Watford” is often said to mean this Watford rather than the Hertfordshire one at Junction 5, seventy miles south — though which of the two the saying originally meant has never actually been settled. There is a site on each carriageway, linked by a footbridge. Drivers still call it the Blue Boar, after the original operator.
