I presume we aren't using most bridges as interstellar antennas.

any like area of metal will receive as much interstellar emissions but I guess they did run a MW transmitter sometimes.

No, but there is a lot of potential for large structures to act like an accidental antenna and/or receive low level voltages from the environment or other equipment.

Likely won't matter in most cases, but there could be a few disasters waiting around.

That’s what the government (… and most rational people) wants you to think.
