The state highway department is widening a road next to a cemetery. How will the souls (or ghosts) react to being so close to traffic?

If you for some reason believe in souls and the afterlife, then there would be no souls dwelling in the graveyard, as they have since moved on to higher planes, or firy pits. Maybe there would be less than a handful of ghosts roaming about, having failed to resolve their last mortal desire. But nobody cares about those, so fuck ‘em.

Highways are for the living

The spirits will like being that close to traffic. They will get to hear snatches of songs they remember from their living days, children’s laughter, people’s voices.

There will be a sudden rise in paranormal activity!!!NOTHING pisses off a ghost/soul more than being interrupted from a good nap.

They won’t like it and you can expect increased paranormal activity especially in the run up to Halloween. They will drift across the road causing accidents in the dark and they will get mixed up with children going trick or treating. As a precaution don’t let anyone into your home, if a ghost should slip in you will have terrible trouble getting them out again.

Maybe they are excited about the fact it makes it easier for their loved ones to visit

It’ll drive them crazy.
They will go into overdrive to put a stop to it.
But they will finally yield and reverse their position.
