You have a good sense of style and it looks like some decent video editing and effect skills as well. I won't belabor the point, but flying over bridges and thruways runs the risk of a collision with aircraft that follow low over these structures. In most urban areas traffic and police helicopters fly low over bridges and thruways and flying your drone over such things, particularly during rush hour or when there are traffic incidents, is a recipe for a collision which would likely result in the death of everyone on the helicopter and risk to those on the ground that the debris might fall on.
Don't be that guy!
