Smart Motorway gantry sign
A gantry structure spanning the motorway with electronic signals, blue signs showing a "tiger tail lane drop" where the left lane exits, the right hand two lanes continue ahead and the second lane from the left can go in either direction, and the following text.
Exit destinations: M42 ; The NORTH EAST; N.E.C. & [Airport symbol].
Forward destinations: The NORTH WEST; Birmingham (W, N & C) M5 .
Junction number: 4A.
The motorways around Birmingham are so busy, here at the heart of the English motorway system, that it’s hard to believe the M5 and M42 were only connected up as recently as 1987.
