A gantry structure spanning the motorway with electronic signals, blue signs showing an exit and the following text.
Exit destinations: A610 Nottingham.
Forward destinations: The SOUTH, London, Leicester [Hollow circle diversion symbol] M1.

It doesn't look much on a map but the A610 will get you in to Nottingham with surprisingly little fuss. Or, if you turn right here, it'll get you to Ikea.
