Just traveled from N. Covington. I-55 southbound from I12-closed. Causeway-closed.
Your best bet would be I-10 from Laplace or Airline Hwy. Spoke to someone who entered Jeff parish to rescue some sick elder woman the other day. Took some convincing but they got through. I have no info on water except what has been posted.
I hear the native are restless and on the loose. Lock and load.
Good luck and be safe.
