A gantry structure spanning the motorway with electronic signals, blue signs showing an exit and the following text.
Exit destinations: A5183 Redbourn.
Forward destinations: The NORTH, Luton & [Airport symbol] M1.
Junction number: 9.
This used to be a junction for the A5, and signposted for places much further afield, but since junction 11A opened further north it's now just where we meet the A5183, which is the former course of the A5. As a result all the important places have been removed from the signs, leaving the little village of Redbourn heralded in foot-high lettering.
