I think those are lights at the topmost parts of the bridge, nothing more than that.

This alone shows it was intentional.

I did not see explosions on port video but there was black smoke coming out of its stack...also their lights came on when just before they hit the bridge! But I will watch the video again...no coincidences!

There are so many videos out that people keep covering different points of everything that happened, Those that think this was not Nefarious I don't even know what to say. Plus there's another bridge somewhere else can't remember where. But did you know that the guy they named that bridge after wrote the star-spangled banner.
