A gantry structure spanning the road with overhead green signs showing an exit and the following text.
Forward destinations: The NORTH; (M25 West) M1 [Motorway symbol] .
Left turn destinations: A1 (M25 East) (A41); Hatfield, Mill Hill .

The right-hand lane departs here for the M1 - feel free to take this exit if you'd prefer the all-motorway route to Yorkshire. The other two lanes dive down a sliproad to continue through the suburbs for a bit longer.
