A-road gantry sign
A gantry structure spanning the road with overhead green signs showing the left two lanes exiting and the other two lanes continuing ahead, and the following text.
Left-hand two lanes destinations: (M11, M1) Stansted [Airport symbol]; A282 (M25) ; [Charging scheme (toll) symbol] .
Right-hand two lanes destinations: (M11, M1) Stansted [Airport symbol]; A282 (M25) ; [Charging scheme (toll) symbol] .
The four-lane carriageway divides into two since we are about to use a pair of two-lane tunnels to pass under the river. If you're in a car you can pick whichever you like, but in a bigger vehicle the right-hand bore has a more generous height limit.
