Smart Motorway gantry sign
A gantry structure spanning the motorway with electronic signals, blue signs showing an exit and the following text.
Exit destinations: A243 Leatherhead, Dorking.
Forward destinations: Heathrow [Airport symbol] (M4), Watford (M1); Guildford (A3) M25 .
Junction number: 9.
Leave here also for the A24, which is a surprisingly quick way south to the coast at Worthing, and a horrifyingly slow way north to London.
