Motorway gantry sign
A gantry spanning the motorway with blue overhead signs indicating one lane exiting and four continuing ahead, and the following text.
Left lane destinations: A3113; Heathrow [Airport symbol]; (Terminal 4, 5; & Cargo) .
Right-hand four lanes destinations: (M4, M40, M1), Watford; Heathrow [Airport symbol] (Terminals 1, 2, 3) M25 .
Junction number: 14.
This junction sits amidst the odd semi-industrial hinterland that airports seem to gather around them - reservoirs and warehouses and gravel workings. But it's also close to some extremely well-to-do villages who prefer not to discuss their proximity to Heathrow and the M25.
