This the Burlington Skyway. It has quite a history.. All the bridges before the Skyway were all destroyed by boats crashing into them. The Skyway began construction in 1957. From the beginning strange occurences have plagued the bridge. A crane operator was lifting materials when out of nowhere high winds hit the crane knocking it on to high tension electrical wires. The crane operator escaped in time but the electrical wires broke wrapping around a car below with passengers. Later that same month another crane suddenly began to fall apart tumbling off the bridge onto 7 cars below.
Over the years many people have jumped from the bridge. The few survivors report having suddenly being struck with "a strange urge to jump off the bridge."
There has also been "ecto mist" in the form of a blue colored orb being seen by many, some have photographed the orb.
There are a few...only a few, who know the truth. A certain cryptic has been seen conjuring mystic forces.

Maybe it's wisp fire they are seeing. With all those "accidents" a wisp is a likely culprit!
