Umm, let's see... I was on this side when it happened. So I'll start with that.

[He figures this might be easier for someone who wasn't involved to uderstand.]

After it became apparent that people were trapped in Westport, the people here tried everything they could think of to get the road to open again. None of it worked though. And it seemed like the town was mocking the effort. They even aired a fake broadcast of the victims enjoying a picnic in Westport. And later on a graveyard appeared. With a grave for each person that was trapped.

I'm actually not sure if the radio broadcasts were intentional or accidental though...
