UPDATE: And more here.
Broadcast news outlets in western Kentucky are reporting that the Eggner Ferry Bridge, which crosses the Tennessee River in the Land Between the Lakes area, has partially collapsed after being struck by a barge.
That's about all that is known or reported at this time.
UPDATE: Now they're saying the bridge was struck by a "cargo ship." I looked up the Delta Mariner, and this is what I found.
And here's more.
