Motorway gantry sign
A gantry spanning the motorway with blue overhead signs indicating one lane exiting and three continuing ahead, and the following text.
Left lane destinations: M69 ; Birmingham; Coventry; A5460 ; Leicester.
Right-hand three lanes destinations: The SOUTH, London M1.
Junction number: 21.
The roundabout at junction 21 is the terminus of the M69 and the main junction for pretty much all of Leicester, so unsurprisingly it is, by any measure you care to choose, one of the UK's busiest roundabouts.
