A gantry structure spanning the motorway with electronic signals, blue signs showing an exit and the following text.
Exit destinations: A610 Nottingham, Ripley.

If you're not local to Nottingham the importance of the A610 might have passed you by. It's quite a high capacity expressway north west from here, and there are some sizeable towns strung along it towards Ripley and the A38.
