A ghost slip or stub is the term applied to any motorway sliproad (exit) that was only ever half-built, usually leaving a couple of small stubs in the hard shoulder. They are the most obvious sign of a half-built service area, but can also mark where another motorway was meant to join.

This shouldn't be mixed up with police patrol ramps, which are similar in appearance but usually at a higher level than the rest of the road and signed as such. These were purpose-built for police cars to watch traffic, but are rarely used these days.
