Unlike the superior US bridges collapsing from neglect.
Making America Great Again, pre-transportation era.
What bridges have collapsed due to neglect in the US?
here one that did here in Minneapolis,MN http://www.mprnews.org/story/2007/08/02/inspection (written the day after.)
the I-35W bridge into downtown Mpls. collapsed on Aug. 1st, 2007.

NTSB:
The gusset plates at the U10 nodes, where the collapse initiated, had inadequate
capacity for the expected loads on the structure, even in the original as-designed
condition.
The bridge failed not due to neglect, but due to poor design.
In fact, the weeks leading up to the collapse the bridge was undergoing refurbishing and repairs to address the fact that it was seriously degraded and federally defined as 'structurally deficient'. even in your link the state bridge engineer 'Dan Dorgan' provides the statement: "We thought we had done all we could..." because the week before they repaired and replaced several key joints and support columns which was done specifically to prevent a collapse.
It was not neglect which caused the bridge to fail.
but it was the lack of inspections that gave no warning to how soon the plates would fail. One of palenty's budget cuts prior to the collapse was bridge inspectors.
prior to that collapse, the closest inspection was when?
and the next inspection was due when?
and the collapse happened when?
and the state of Minnesota settled with the victims/survivor's of the collapse when?
one of the myriad of reasons palenty didn't run for another term was he was going to get skewered about the budget cuts to the bridge inspectors. If I had time to I would find the spacing of inspections prior to those cuts. but right after the collapse, check the number of bridges with flaws like it inspected hmm?
as a Democrat in this city, that was widely known to be a campaign point he was going to have ads run on him about.... and he knew it and he's not shown his face around here since.
If I do understand your pigin you seem to be saying that inspection was the problem, yet your article says it was the initial design. Just so you know, inspectors are non-technical people that check and make sure what the design says should be there is what is there. As I don't expect you to understand the process, I'll refrain from mentioning how stupid the comment was.
oh I get it..... ur saying bridge inspectors aren't engineers with at least a bachelors degree or better well..... http://study.com/articles/Bridge_Inspector_Job_Description_and_Requirements.html
Education Requirements
Most entry-level jobs require a high school diploma or GED and certification. More advanced positions require higher education such as a bachelor's or master's degree in civil engineering.
Many universities offer bridge inspection training courses for certification training. The National Bridge Inspection Standards (NBIS) requires that such courses to be approved by the Federal Highway Administration. A typical training course explores steel, concrete and timber bridge evaluation; tools and safety; steel deterioration and waterway evaluation. Students also learn how to understand federal codes and inventory forms.
Certification
The National Institute for Certification in Engineering Technologies (NICET) offers four levels of certification in bridge safety inspection from entry-level to senior level, which can be sought after an inspector gains relevant work experience. Applicants must pass a written exam to become certified. Depending on state requirements, bridge inspectors may also need to gain SCUBA certification to evaluate bridge conditions underwater. To become SCUBA-certified, bridge inspectors must complete a diving training program. Similar to NBIS-approved training courses, colleges often offer bridge inspection refresher courses to keep inspectors current on regulations and practices or to renew their inspection certification.
Bridge inspectors are pretty smart people with many with majors or minors in metalurgy, CAD, and other construction disciplines. They are as technical as the builders and Designers (like Me) whos work they keep their eyes on.
that makes u pretty fucking godawful stupid... Again!! non-technically speaking of course,.... just sayn'
Actually, your level of "ignance" regarding what you just posted makes it impossible to actually respond to you. You don't even understand what you don't understand. Let me just point out one. A major or minor in CAD. Do you know what that is? It's Computer Added Drafting. Somebody tells them what to draw and without understanding why, they draw it. Now, you may have to be pretty smart to do that, obviously beyond your intellectual talents, but it doesn't even imply they know how to calculate a shear or moment on a bridge structure. (Ya, I used technical words you can...maybe...Google)
