I'm a radio nerd so I'll leave a bit of information about the bridge. This bridge has a radio station which goes by the callsign WNKG901. It transmits on 1700 AM and is a Travellers' Information Station. These stations are low powered AM stations often found along highways or in national parks. They broadcast information about the road, traffic conditions, safety such as accidents or forest fires, inform users of how to receive help and to offer suggestions for points of interest for visitors.
An interesting thing about this bridge re: safety is that it has its own police force due to it being so fucking long.
You can listen to a recording of the one for this bridge here:
