Though this practice of naming junctions after the names of local
businesses
is rather vulnerable to them changing their name. The Nags Head on
Holloway
Road (at the A1/A503 junction) was renamed to some Irish-themed name a few
years ago despite the old name appearing on road signs and bus timetables.

It was a particular pain in the ass when the Spaghetti factory near Junction
6 on the M6 changed from producing Spaghetti to Fettuccine.
