One thing I learned while researching "arc fire", my own electricity person, is that comic book electricity people are bloody impossible. Electricity is always drawn towards negatively charged objects, most often of which is the ground. Unless carried by a gas, a tether or a laser beam electricity always turns towards the ground or large chunks of metal.

Then again, Superman and other bricks can't lift half of the things they do. You can't lift a building or a supertanker. They'd collapse under their own weight! Thus, all bricks must be telekinetic? A good example is hulk trying to stop a train with his bare hands. The limiting factor is the friction caused by the surface area of his feet on the ground. I did the math years ago (and I'm ashamed I can't do it anymore) and it was several kilometers. Needless to say, here's hoping the bridge isn't out.
