Miami pedestrian bridge collapse

I like watching people respond to one.

An example is the hype surrounding the upcoming meeting between N Korea and us.

What meeting?

There's an update over on Welding Web, posted by Tigatoo.

Here's one of the photos in it.

Hey, Cali,,, the way you linked it, you gotta be a weldingweb member to view it,,,

AFAIK, all these pics were taken before the bridge collapse.

By the looks of those cracks it appears the bridge was starting to move a few days before it went down, I find it hard to belive that they didn't close that road after seeing that.

Oops, sorry. Last night a link to Miami Herald's photo returned nothing so I substituted Tigatoo's downloaded copy of it. Maybe I didn't wait long enough. Today the link works so I updated the post above. The photo is the final one in the Miami Herald article.

Looks to me that the measuring stick probing 6 inches into the 'crack' illustrates separation of Diagonal #11 from its attachment point.

That would take a bit of poly filler.

When will the investigation make its results known?

I wonder if the "TRUTH" will ever come out?

You'll have to define "truth." If you meaning blaming someone - no. The NTSB is conducting the investigation. They are precluded by Congress from issuing reports that include finding fault or blaming someone as Congress does not want the agency acting as an expert witness and/or testifying in court. They will only document the mechanisms that caused the failure. That could include: design, materials, construction methods, etc.

The NTSB is a totally independent agency. They are not part of any other federal department so they do not answer to appointed heads of departments. While most people are familiar with the NTSB's role in investigating aviation accidents, they have a number of different offices (divisions) dedicated to investigating accidents associated with: railroads, pipelines, hazardous materials; aviation safety; highway safety; marine safety.

They have investigated hundreds of bridge failures and accidents - you can find the reports on their website. There is no other investigative agency that can perform the investigation to the level of the NTSB, because if required, they will build replicas of the portion of the bridge that failed and test the replica for structural performance.
