Smart Motorway gantry sign
A gantry structure spanning the motorway with electronic signals, blue signs showing the left lane exiting and three others continuing ahead, and the following text.
Exit destinations: A444 [Solid square diversion symbol] ; Coventry (N); Nuneaton; B4113 ; Bedworth.
Forward destinations: M6 ; The NORTH WEST, Birmingham.
Junction number: 3.
The A444 is the main road north from Coventry, and in the early 1970s this junction was built with enough space for it to get an underpass below the M6 and the big roundabout - but there's no sign that one will ever now be built.
