A lot of us did come over here and bring some good building skills with us.

We still own quite a number of construction companies.

Waiting for mafia comments..3..2..1... :)

What’s really sad is that a coat of paint on the bridge would have prevented the corrosion and collapse.

[Sirius Lee]

Did anybody see the Mothman in the weeks before the collapse?

If you put too many bodies in the concrete, it weakens the construction.

Great article, TSR...thanks for posting it.

[Mr. Blond]

Not enough rebar.

A few minutes later, a 200-metre section of the bridge collapsed, including one of its three supporting towers. The tragedy killed 43 people and left 600 homeless.

A bridge collapsed, and left 600 people homeless? What?

Concrete by itself has very little tensile strength.

Corrosion of the reinforcing materials (Rebar/cables) in 50 years of sea air(salt) and and industrially pollution environment ...

Insufficient maintenance ...

“The engineer (who designed it) recommended using an epoxy resin to cover the reinforcements with materials “of a very high chemical resistance”. (wasn’t done)

Riccardo Morandi *(the designer) wrote a report in 1979 recommending constant maintenance of the structure to remove all traces of rust and fill in exposed patches on the reinforcements. (wasnt done sufficiently)

I wonder if the new concrete bridges being built in the US have have a similar ‘low bid’/’slacker’ situation.
