My little brother found out about the I-35W bridge that collapsed nearly. 8 years ago today.

He asked me "Why didn't the Engineers who built it do a better job?"

I didn't know the answer. I did a little reading and found that as early as 1990 it had been considered structurally deficient.

With all the time given why wasn't more done to fix the problem(s) of MN busiest bridge?

Edit: or what else could the Engineers have done, if any?

You should watch the John Oliver piece on Last Week Tonight about infrastructure around the country. A lot more bridges will probably be collapsing in the coming years.

There are a shotload of structurally deficient bridges throughout the country--funding is the issue.

I tend to get nervous about that LA 1 bridge across the Intracoastal.

IIRC, there were some gusset plates near the initial failure point that were only half the design thickness.

There was also considerable loading from construction equipment, material and supplies; as well as bumper to bumper rush hour traffic.

Isn't the I-10 bridge in Lake Charles pretty bad off structurally as well? The bridge scares me. Next time you drive across it, look up at the horizontal beams just above your vehicle...they are pretty twisted/distorted.

.18 cents a gallon for highways/bridges to the federal gov't and this is what we have to show for it. How many gallons of gas are sold a day? You do the math.

There's a ton of infrastructure in this country that needs serious work.

It should be thought about like the law of gravity or relativity: if the government has x amount of revenue, the government will waste x minus whatever they can use to bribe the electorate. The embarrassing roads and bridges in this country won't be fixed until we the electorate start caring enough to scare the pols.

Yep, shear failure of gussets. I don't remember if it was design or contractor error.

I want to say it was a contractor & inspection problem, but maybe they were under/designed.

There's plenty of money, it just goes to other stuff.

True...there's one party that wants to fix infrastructure, another party doesn't think it's all that serious. I'll let yall fight over the parties.

You mean one party wants to get rich one way while another uses a different avenue.

Did they address the gusset plates? Was it a design flaw, fabrication error, or a construction/inspection problem?
