Motorway gantry sign
A gantry spanning the motorway with blue overhead signs indicating two lanes exiting to different places, and four continuing ahead, and the following text.
Left lane destinations: Heathrow; [Airport symbol]; (Terminal; 5 only) .
Second lane from left destinations: A3113 [Hollow square diversion symbol] ; Heathrow [Airport symbol]; (Terminal 4; & Cargo) .
Right-hand four lanes destinations: (M3, M23, M20); Staines (A30), Gatwick [Airport symbol] Dartford M25 .
Junction number: 14.
Heathrow's colossal Terminal 5 came with a whole range of changes to the M25, including this interchange. New sliproads were woven through the existing structure of junction 14 to create a new link road to the terminal, opening in 2008.
The next section, from J14 to 13, opened in August 1982, but it's unrecognisable now.
