Comment: I recently heard the Coronado Bridge, from San Diego, CA to
Coronado, which contains a naval base, is mined for self-destruction. Is
there any truth to this?

I think that somebody has their facts confused and may be thinking about this news report from 2002.

When I was living in San Diego I once went on a harbor cruise. During the cruise we went under the Coronado bridge and the tour guide told us that the bridge was engineered to be collapsed in the event of national emergency so that large numbers of navy ships could move in and out of the harbor without obstruction from the bridge. No mines--just sections that would collapse in a pre-determined order. I'm not sure if this tour guide was just passing along the UL or not, but the idea that it is engineered to come down in sections seems much more feasable to me than it actually blowing up.

I see no logical military reason why they would rig the Coronado bridge for self-destruction. The pilings of the bridge are hardly enough of an obstruction to shipping to justify that. Chunks of bridge falling into the water would be much more of a detriment to navigation.

Actually the Chesapeake Bay Bridge in the upper bay is like that, and so are sections of the bridge/tunnels near Norfolk. the tunnels are rigged to colapse so the channels are deeper. Really, more new obstructions help ships get out faster [Wink]

I was just down there a couple of weeks ago, visting an uncle on the island, and I'll confirm, that, AFAIK, the bridge is definitely high enough, and the pilings far enough from each other for any ships to get through, no prob.

For anyone unfamiliar with it, it looks like this:
 -
Higher res, different angle
I would imagine most ships would be able to fit under it fine.

Greetings,

/slight hijack

Is that bridge really curved like that, or is the lens/angle/something else making a straight stretch of road look like it turns? If it is curved, is it going around something? Wouldn’t it be much less expensive to build a straight bridge?

The bridge is really curved like that. I have driven on it a few times when on vacation in San Diego.

Apparently, it is curved to make it longer...so that the grade is less steep.

I've been over it on a motorcycle, back in the day when you didn't have to wear a helmet. Great view....

The bridge is curved to make it longer...longer so it can be higher...and higher so that most Navy ships can pass under it to get to the 32nd Street Navy Base and the shipyards and dry-docks there.

There is a standby plan to blast an emergency channel through the isthmus -- "The Silver Strand" -- so that if the bridge were collapsed, or if the mouth of the harbor were blocked, the Navy vessels could escape.

Not only do the have signs, but they have an actual phone at the midpoint that goes straight to the suicide hotline if you pick it up.

I remember driving over the bridge in the Driver's Ed car.
