A-road fork sign
A green sign with a diagram showing an exit branching off the road ahead and the following text.
Forward destinations: C. London; Brent Cross; A1 [Hollow triangle diversion symbol].
Exit destinations: Borehamwood; A5135; Barnet; Arkley; (A411).
Borehamwood is joined at the hip with Elstree, and together they are home to a number of historic film and TV studios. Look out for A-list movie stars exiting the A1 here. Well, you never know, do you?
