What is the correct phraseology for instructing a vehicle/aircraft to cross a runway?

Explanation:
In this situation you must state exactly which runway is to be crossed and where the crossing will occur. The clear, standard pattern is: Cross Runway [designator] at [taxiway or another runway]. This directly communicates two essential details: which runway to cross and the precise crossing point (the taxiway or the other runway). That’s why this option is the best—it allows specifying the runway to be crossed and the crossing point in one unambiguous instruction, such as “Cross Runway 09 at Taxiway Alpha” or “Cross Runway 09 at Runway 27.” Other formulations can be ambiguous because they omit the specific runway to be crossed or place the location in a way that doesn’t clearly denote the crossing point.
