Mmmmmmmmmmmmm , maybe a couple of nice Red illuminated warning signs posted on each side of the offending area-------"Stop, a/c above XXm wingspan do not enter"
Maybe that might help!!
If one misses the other information, signage, and indicators, clearly a couple small signs wouldn't be enough. After all, that's what was missed before. Far more effective would be a laser array buried in the ground at the wingspan width limit, aimed at the sky, and if an aircraft wing breaks the beam a barrage of star shells are automatically fired into the line of sight of the cockpit to alert the crew. If the crew still doesn't get the message, a 2nd laser array will trigger a barricade net to be raised across the taxiway in front of the offending aircraft.
This system would probably be adequate in terms of outcome and airports not being liable for criminal negligence, and there wouldn't be a need to retrofit all aircraft with tailhooks automatically extended through some sort of proximity sensor (as would be required if arresting-wire systems were installed).
