More Than 47,000 'Structurally Deficient' Bridges In The U.S.

[longknife]

Think of that next time you cross one.


My granddaughter is studying civil engineering at UNLV and has a part-time job with the Nevada DOT. She says that part of what she does is examine bridges in Southern Nevada to assess their structural integrity. She tells me a lot of them have failing grades.

"Structurally deficient" doesn't mean the bridges are about to collapse, says Alison Black, chief economist for ARTBA. It just means the bridges are in need of renovation but are not unsafe for crossing, she tells Here & Now's Peter O'Dowd.

The number of structurally deficient bridges is actually down by about 7,000 from 2017, but those bridges weren't fixed. The number fell because the Federal Highway Administration weakened the standards of what it means for a bridge to be deficient, the report explains.

Why? What caused them to lower the standards?

The report notes that these deficient bridges are crossed some 178 million times a day. Some of the most notable bridges deemed deficient in the report include New York's Brooklyn Bridge, which opened in 1883; Memorial Bridge connecting Washington, D.C. to Arlington, Va., across the Potomac River; the San Mateo-Hayward Bridge, which spans California's San Francisco Bay; and Florida's Pensacola Bay Bridge, which is known among locals as the Three-Mile Bridge.

"Structurally deficient" doesn't mean the bridges are about to collapse

Yeah well it doesn't mean anything until it actually does collapse which is unfailingly accompanied by shock and surprise and subsequent moving of the standards.

"Structurally deficient" doesn't mean the bridges are about to collapse, says Alison Black, chief economist for ARTBA. It just means the bridges are in need of renovation but are not unsafe for crossing, she tells Here & Now's Peter O'Dowd.

The number of structurally deficient bridges is actually down by about 7,000 from 2017, but those bridges weren't fixed. The number fell because the Federal Highway Administration weakened the standards of what it means for a bridge to be deficient, the report explains.

Why? What caused them to lower the standards?

The report notes that these deficient bridges are crossed some 178 million times a day. Some of the most notable bridges deemed deficient in the report include New York's Brooklyn Bridge, which opened in 1883; Memorial Bridge connecting Washington, D.C. to Arlington, Va., across the Potomac River; the San Mateo-Hayward Bridge, which spans California's San Francisco Bay; and Florida's Pensacola Bay Bridge, which is known among locals as the Three-Mile Bridge.

The design was outdated; more modern types of truss can better withstand such forces.

Hey you missed the best one. The Tacoma narrows bridge collapse. It didn't go down for structural insufficiency but it sure as hell was cool to watch.

Think of that next time you cross one.


My granddaughter is studying civil engineering at UNLV and has a part-time job with the Nevada DOT. She says that part of what she does is examine bridges in Southern Nevada to assess their structural integrity. She tells me a lot of them have failing grades.

"Structurally deficient" doesn't mean the bridges are about to collapse, says Alison Black, chief economist for ARTBA. It just means the bridges are in need of renovation but are not unsafe for crossing, she tells Here & Now's Peter O'Dowd.

The number of structurally deficient bridges is actually down by about 7,000 from 2017, but those bridges weren't fixed. The number fell because the Federal Highway Administration weakened the standards of what it means for a bridge to be deficient, the report explains.

Why? What caused them to lower the standards?

The report notes that these deficient bridges are crossed some 178 million times a day. Some of the most notable bridges deemed deficient in the report include New York's Brooklyn Bridge, which opened in 1883; Memorial Bridge connecting Washington, D.C. to Arlington, Va., across the Potomac River; the San Mateo-Hayward Bridge, which spans California's San Francisco Bay; and Florida's Pensacola Bay Bridge, which is known among locals as the Three-Mile Bridge.

Much more @ Report Finds More Than 47,000 'Structurally Deficient' Bridges In The U.S.

The design was outdated; more modern types of truss can better withstand such forces.

Hey you missed the best one. The Tacoma narrows bridge collapse. It didn't go down for structural insufficiency but it sure as hell was cool to watch.

Jo

I was thinking of that one, Just posted 2000 till today, I never saw the security video of the Minneapolis collapse till now in that GIF.......... that was messed up.

 

[Lumpy 1]

Think of that next time you cross one.


My granddaughter is studying civil engineering at UNLV and has a part-time job with the Nevada DOT. She says that part of what she does is examine bridges in Southern Nevada to assess their structural integrity. She tells me a lot of them have failing grades.

"Structurally deficient" doesn't mean the bridges are about to collapse, says Alison Black, chief economist for ARTBA. It just means the bridges are in need of renovation but are not unsafe for crossing, she tells Here & Now's Peter O'Dowd.

The number of structurally deficient bridges is actually down by about 7,000 from 2017, but those bridges weren't fixed. The number fell because the Federal Highway Administration weakened the standards of what it means for a bridge to be deficient, the report explains.

Why? What caused them to lower the standards?

The report notes that these deficient bridges are crossed some 178 million times a day. Some of the most notable bridges deemed deficient in the report include New York's Brooklyn Bridge, which opened in 1883; Memorial Bridge connecting Washington, D.C. to Arlington, Va., across the Potomac River; the San Mateo-Hayward Bridge, which spans California's San Francisco Bay; and Florida's Pensacola Bay Bridge, which is known among locals as the Three-Mile Bridge.

Much more @ Report Finds More Than 47,000 'Structurally Deficient' Bridges In The U.S.

Wow, thats a lot! How many of those bridges fall each day?

Like everything else, our rotting bridges won't be a problem until the next one collapses with people driving on it. If the death count is high enough then we'll do something about it. If only a couple of people die, then it will be "Gee that's too bad, now back to TRUMP!"

If a bridge collapses on earth or in space .. it's Trump's fault...

Yet at least 20% of the highway trust fund gets hijacked to pay for money-sucking urban mass transit and choo-choo trains that almost nobody rides.

Think of that next time you cross one.


My granddaughter is studying civil engineering at UNLV and has a part-time job with the Nevada DOT. She says that part of what she does is examine bridges in Southern Nevada to assess their structural integrity. She tells me a lot of them have failing grades.

"Structurally deficient" doesn't mean the bridges are about to collapse, says Alison Black, chief economist for ARTBA. It just means the bridges are in need of renovation but are not unsafe for crossing, she tells Here & Now's Peter O'Dowd.

The number of structurally deficient bridges is actually down by about 7,000 from 2017, but those bridges weren't fixed. The number fell because the Federal Highway Administration weakened the standards of what it means for a bridge to be deficient, the report explains.

Why? What caused them to lower the standards?

The report notes that these deficient bridges are crossed some 178 million times a day. Some of the most notable bridges deemed deficient in the report include New York's Brooklyn Bridge, which opened in 1883; Memorial Bridge connecting Washington, D.C. to Arlington, Va., across the Potomac River; the San Mateo-Hayward Bridge, which spans California's San Francisco Bay; and Florida's Pensacola Bay Bridge, which is known among locals as the Three-Mile Bridge.

Much more @ Report Finds More Than 47,000 'Structurally Deficient' Bridges In The U.S.

Wow, thats a lot! How many of those bridges fall each day?

got to love the internet, I found the picture of you when it happened

 

[Natural Citizen]

Yet at least 20% of the highway trust fund gets hijacked to pay for money-sucking urban mass transit and choo-choo trains that almost nobody rides.

Also to pay the interest on that Treasury bond that the federal reserve bought with a check that was drawn on an account that had nothing in it in order to pay for all the free shit the politicians ran on. Ha. Crazy.

 

[Lumpy 1]

The worst part is I can't build a new one.. permits, environmental studies, blah blah, red tape, money and such.

Lucky that tree fell over and it just happens to work..

One would think a government spending Trillions annually would fix it's bridges, but apparently not.

Hence that is why we have Brian Stelters! Joy Reid and Symone. And so many others. Murderers come in many flavors. And they remain confident and arrogant until caught. Then they either repent or stay the same when justice comes for them.

Think of that next time you cross one.


My granddaughter is studying civil engineering at UNLV and has a part-time job with the Nevada DOT. She says that part of what she does is examine bridges in Southern Nevada to assess their structural integrity. She tells me a lot of them have failing grades.

"Structurally deficient" doesn't mean the bridges are about to collapse, says Alison Black, chief economist for ARTBA. It just means the bridges are in need of renovation but are not unsafe for crossing, she tells Here & Now's Peter O'Dowd.

The number of structurally deficient bridges is actually down by about 7,000 from 2017, but those bridges weren't fixed. The number fell because the Federal Highway Administration weakened the standards of what it means for a bridge to be deficient, the report explains.

Why? What caused them to lower the standards?

The report notes that these deficient bridges are crossed some 178 million times a day. Some of the most notable bridges deemed deficient in the report include New York's Brooklyn Bridge, which opened in 1883; Memorial Bridge connecting Washington, D.C. to Arlington, Va., across the Potomac River; the San Mateo-Hayward Bridge, which spans California's San Francisco Bay; and Florida's Pensacola Bay Bridge, which is known among locals as the Three-Mile Bridge.

Truss bridges like this one require both the top and the bottom to remain equal in strength and solidity. When the truck hit the top girder, or girders, this caused the pressure/squeeze system to fail, which made the bridge fold up. The design was outdated; more modern types of truss can better withstand such forces.

What the hell is that list? We are talking about American bridges collapsing on their own. How many of the 47,000 mentioned in the OP fall each day? Surely if they are as bad as the OP suggests, several of these bridges would fall each day.

 

[Natural Citizen]

Speaking of busted bridges, there's still some nice ones, very scenic. One of my favorite things to do whenever my son was playing there at Cambell's Field in New Jersey was jump on Interstate, head to the ball park and buy a ticket. Right on the river front, too. Beautiful evenings there, I'm blessed. The River Sharks are moving, though, they started tearing Cambell's Field down already. Good memories there.

It has a very nice bridge, kind of old. The Ben Franklin Bridge, actually. It has pedestrian walkways on both sides, two tiered, I think. It's hard to find pictures online with the whole bridge in the picture, I have some but I don't feel like going through them.

I'l just have to wheelie over them.
