Dr. Gerald Craddock:

There is the example and the photo that was sent to us from Coventry in the UK. It is a motorway with an off ramp. If one is leaving the motorway, on top of the off ramp normally there would be the bridge going back if the driver needs to get back onto the motorway on the other side, as there was in this case. On top of that off ramp they created a shared space.
