Thanks! Hubby is down in that area tonight, and he might try to see what he can see. Sounds like they were lifting sections of concrete today, so that would explain the findings.

Morning update....two vehicles recovered, with remains. I believe this includes last night’s recovery.

Looks like they’ve found someone this morning:

An amazing feat, considering the rain the past couple of days. I’ve heard that these Navy divers are physical dynamos.

Sounds like they know who it is that they found:

Don’t know that I can refer you to an exhaustive engineering lexicon. I have heard of engineering dictionaries, but I don’t have one. My references come from a combination of textbooks and field experience. The most general form of all the bridges discussed here thus far are trusses. If you read the first paragraph of the wikipedia entry cited, it says a cantilever can be made of trusses or steel or concrete beams. The truss cantilevering doesn’t preclude it from being a truss. The Firth of Forth Bridge pictured is a truss bridge. It employs cantilever sections over the piers to reach out and support the much shallower suspended or “drop-in” spans at mid-span. I disagree with the articles contention that the Jeremiah Morrow and Newark Bay Bridges are cantilevers. A cantilever requires a hinged section. It it not obvious those bridges have hinges.

The Newark Bay Bridge is an example of a Truss Arch. Think of it this way. Simple trusses don’t continue over their supports. Each span of a simple truss is independent. Continuous trusses are dependent on their adjacent spans, hence the height at the piers. Truss spans employing a cantilever (i.e. locating the hinge somewhere other than the pier) could be considered a hybrid of simple and continuous trusses. Sorry I didn't answer sooner. Your question wasn't shown as a new post to me.

The last person has been found. Thank goodness that phase of the work is done.

10 year anniversary.

[Freedom56v2]

Should this be in Breaking News??

Links?

[ButThreeLeftsDo]

It was Breaking News 10 years ago tonight.

[Freedom56v2]

Wow...Why did you not clarify that...I have relatives there!!! Sheesh.

[ButThreeLeftsDo]

I posted an update to a 10 year old thread.

Certainly you know how to read thread dates.

;-)

[ButThreeLeftsDo]

Sorry for the confusion.

I live here, too.

This sounds horrible. I think I might have driven over that bridge just last year.
