Dr. Nehemiah Mabry, PE, knows a lot about bridges. Nehemiah is a structural engineer and an educator; and he builds bridges for a living. Dr. Mabry sits down with WIRED to talk about all different kinds of bridges from around the globe. What’s the difference between a cable-stayed bridge and a suspension bridge? Are bridges in China different from bridges in the United States? Why do they decide to build one bridge over another type of bridge?

    In central Canada where it can get to minus 50 below zero. For 3/4 months the pillars of the bridge are incased in thick ice, in deeper rivers the water is still rapidly flowing under the ice. Is this a good kind of pressure for the bridge or not ?

    By the way excellent commentary on bridges. This engineer not only is knowledgeable on structures, but he’s awesome at communicating it. 5 outta 5 for me.

    Why tf are there arrows added in post? First off, they don’t make his point any clearer. And Secondly, they are demonstrating shear forces, not tension and compression, so they make his point even less clear. Nice job 2:05

    18:05 Names of most bridges in St. Petersburg, Russia are actually translatable. Sorry, but there is no “Dvortsovaya Bridge” in our city. It’s one of: “Palace Bridge”, “Dvortsoviy Most” (pure name transliteration), or “Дворцовый мост” (the original name). Moreover, it’s incorrect to use the word form “Dvortsovaya” in conjunction with a bridge in Russian as the former is feminine and “bridge” is masculine. I guess, it is ok to say Dvortsoviy Bridge but it seems like it is not incorrect.

    Nevertheless, the video is great. Thanks to Dr. Mabry!

    Gonna be blunt here, feel like they used the same lighting for white engineers and scientists when they did videos in the set with them. Maybe they tested it with one of the lighting guys and we’re like “seems good to me” with any lack of other people. Interestingly enough though, couldn’t the camera guys raise exposure a bit and played around or even the editing guy? How many stages of people failed the lighting here and didn’t see a problem? what hahaha

    Your tension/compression arrows should be aligned, or else it’s a shear stress. It will confuse new would be engineers.

    The part about cable stayed bridges is actually not accurate, the main benefit is because its cheapest to build. For actual Longer spans, suspension bridge is absolutely the best option. That said, being economical is a MASSIVE advantage. Afterall, a bridge is primarily a functional structure and not an aesthetic structure.

    Really interesting video, one thing I’d like to say about the bailey bridges, while they are/were supposed to be temporary, they were usually really well made. The US army left some bridges in my country after WW2, and some are still operating today… Sure usually they can’t carry very heavy weights anymore and stuff like that but there was a bailey bridge between 2 villages near my town that was working as actual road bridge (as in, not just for pedestrians but also for cars) until last year… AFAIK they didn’t actually demolish it, but instead took it apart and rebuilt it in some military history museum…
    And as for stone arch bridges being able to last long, we have multiple very old stone bridges here in europe, not just the aquaduct, for example the Charles Bridge, built in 1348, in Prague is my favourite, and it can carry an incredible load… Well an incredible amount of overweight american tourists, but that’s a great load bearing test imo 😀

    November 20, 2020 at 10:45 pm

    Who was in charge of this video???? The lighting, the graphic design, the interviewer that sounds like a voice over…. that`s some really bad production. luckly the guy made the video some what interesting.

  71. David Williams

    November 20, 2020 at 11:38 pm

    I could listen to this guy talk about this all day. Love it.

    But like, it kind of bugs me that they *only* used the deceptive wide angle shot for the Eshima Ohashi Bridge. Like yeah, a 6% grade is nothing to scoff at, it’s still steep for a bridge. But without the depth of field being distorted it doesn’t look that crazy at all.

    The arrows at 2:06 and 2:14 should be on the same axis otherwise you are representing a different type of stress. (I don’t remember the name in english)

    Anyways, cool video!

    This is the sort of video I love – going in-depth with an engineer about how they think about a bridge conceptually, what design problems and constraints they have to address, and how the different solutions differ. This video is particularly well illustrated with animations over the images to emphasizing their points.

    So I was gonna rush down here to complain about this transphobic lighting situation, but it looks like lots of people already took care of that. So I guess I’ll just talk about what the video is actually about? I like bridges!

  92. MCB18

    November 21, 2020 at 10:56 pm

    Why not talk about the third Bosphorus bridge in Istanbul when mentioning hybrid bridges? That is a much more pronounced example of such a bridge. As well as the fact that many of Roebling’s bridges had diagonal stays simply because the technology for such large-scale bridges were not known yet. In reality, the Brooklyn bridge did not need many of those diagonal stays.

    7:30 The forces one the deck/span (horizontal) seem reversed. Shouldn’t it be tension forces (<- ->) at the bottom of the span and compressive forces (-> <-) at the top of the span? Or is the span curved up instead of sagging?

    hey uh, this video is really interesting, but the writing is pretty bad. Maybe fewer leading questions? Or just fewer questions altogether, and let the expert talk more? The reporter’s participation in the video really broke up the expert “lecture” in jarring and unpleasant ways; this was only exacerbated by the “corny” and “leading” nature of the questions.

  211. spambot71

    November 27, 2020 at 4:39 am

    the dubbed “interviewer’s” delivery gets more natural later on in the video, at which point the most jarring part is the mismatch in levels and room response. they should’ve given them a second take at least for the first several questions, as is it’s PAINFUL. tbh a lot of the prompting questions probably could’ve just been left out and replaced with a jump cut and it would’ve flowed just fine

    At 12:52, the entry for the Truss Bridge Type: “Fracture critical (no load path redundancy)”. Regrettably, Dr. Mabry does not discuss this matter in the video. But this aspect of the truss bridge is really important. A number of truss structure failures hinge on this failure mode. Engineers take note.
    Also, the matter of why one type of bridge structure is selected over another in a particular situation is not discussed. Oh, well.

    The Rakotzbrücke (Devil’s Bridge) in Germany is more of a sculpture than a bridge. It isn’t used as a bridge and by the way it doesn’t always look that amazing. I was there last weekend and there was no water and construction vehicles parked under it.

    They kept showing “W/1” and “W/2” for I guess “W1” (or “W_1”) and “W2” (or “W_2”) which is wrong and annoying. Or else they meant W/1 (ie W) and W/2 (ie 0.5 W), in which case they’re wrong.

    This is what my dad does. Surprisingly most bridges are DECADES past due for repair… budget people are often not educated on the safety issues associated with this type of neglect…. just like the lighting person was not aware how badly he truly needed that spotlight that the production budget of this video did not allow for… Moral of the story… if you think a bridge looks unsafe or you have a strong gut feeling to avoid a bridge… you probably should. 😉

  368. empressmarowynn

    December 9, 2020 at 12:13 am

    We have a TON of bridges in my city that were built around the same time and are well past their 50 year design. Some of them need complete redesigns because traffic has dramatically increased since they were built but instead the city just keeps patching up the old ones, even when there are literally chunks of concrete falling off onto roadways beneath. A year ago they finally fully rebuilt one that had a net underneath for about a decade to catch the falling debris. It’s that bad.

    And cars have to wait
    Something they hate
    And drivers get mad
    Tough luck, too bad
    But quick look around

    The next bridge
    Goes up and down

    Interviewee was great, but lighting is awful, interviewer/narrator voice is awkward, plus the questions asked are cringe because they’re forced and don’t have a natural flow. What happened to just letting the interviewees speak and editing out the other voices? Was there no budget for proper lighting and editing?

    Lightning aside, he has a great shinning personality, bridges have always been one of my secret loves, even back when they used to bury bones on both sides of them superstitiously. But his personableness was hamstrung by that machine voice, like just because it’s a female voice it somehow is not annoying, like the sound of fingernails raked over a chalk board stuck in her throat.
