Not important, since I no longer have the car, but always wondered about it. My old car (2004 Mazda6) seemed to have an odd radio quirk. Driving over one particular bridge (The I-95 Susquehanna River bridge, for those in/near MD), radio reception would fade out to nothing. Not static, just silence…and radio reception would come back once off the bridge. This happened with all radio stations in that car… and I’ve never seen it happen in any other car I’ve driven or ridden across the bridge.
The bridge is “open” (no metal superstructure above/ around the travel lanes that could have blocked radio signals). Any ideas what might have caused it?
