Hopefully, someone is thinking ahead of time and will close before the hurricane actually hits the bridge. With that being said, you can always close it at the approaches leading up to the bridge. With an interstate, you close it at the prior interchange. I would have thought that would have happened here, but apparently not. And you can put up warning signs, using the portable signs cops carry with them, using flares, using patrol cars with lights ablazing to warn people not to go any further. You do not do this on the bridge itself, but on the approaches to the bridge.

The one in the second photo in post 76?

And you can put up warning signs, using the portable signs cops carry with them,

If they were lucky, they might find the portable signs in Dothan or Andalusia.

using patrol cars with lights ablazing to warn people not to go any further.

Have you ever driven in a blinding, wind whipped rain where visibility was 30 feet or less? You would be lucky to spot the "lights ablazing" a few seconds before you hit the police car.

How to close a highway in a hurricane.

Check with Wyoming Highway Dept.

They have permanently installed lockable gates with signs & flashers to close the highways due to snow & blizzard conditions.

They are on all interstates and other main roads at strategic points. It is a simple matter for the state police to close, lock, and leave.
