    1. They fired his white ass for bringing too much common sense and laughter in a corporate corrupted media.
      He would have brought some white spray paint to help with Trudeau’s addiction to turn his skin black.

      Krazy glue time…

  3. a perfect shear break. but just out of the maximum shear zone covered by that plate

    1. The Spanish engineer conquistadors?
      Cause it looks way cool compared to the utilitarian railway span next door?
      Coz Kathleen Wynne wanted her Bridge across the River Nipigon, vanity project?

  6. Corrupt political party greasing the public sector Unions for their blind political support and loyalty … sounds like corrupt shithole, Canada.

  8. ““This fracture had the potential of becoming a catastrophic event that was prevented by our staff’s diligent effort in managing our bridge inspection program,” Tudor said.”

    How do you allow a crack to get that large?

    1. “How do you allow a crack to get that large?”

      Embrace socialism. Worked for us here in Minneapolis.

      (Remember the 35W bridge?)

    2. “How do you allow a crack to get that large?” Ask Stacey Abrams.

  9. You wait-and-see – they’ll find a way to blame this on some MAGA hat wearing grandmother who stormed the capital on January 6.

  10. Be Glad this was not designed like the I35W Bridge. The Beam failed, but the bridge did not collapse.

    “The I-35W bridge was designed and built before metal fatigue cracking
    in bridges was a well-understood phenomenon. In the late 1970s, when a
    better understanding of metal fatigue cracking was established within the
    industry, deck truss bridges such as the I-35W bridge were recognized as being
    “non-load-path-redundant”—that is, if certain main truss members (termed
    “fracture-critical”) failed, the bridge would collapse. According to Federal Highway
    Administration (FHWA) 2007 data, of the 600,000 bridges in the National Bridge
    Inventory, 19,273 are considered non-load-path-redundant. About 465 bridges
    within the inventory have a main span that is a steel deck truss.”

    No other crossings within 50 miles? ouch!!!

    I am so glad no one died this time.
    Minnesota replaced several other similar bridges with similar single failure points.
    one was in Sint Cloud MN, and I probably crossed it over 100 times.

  11. “Arkansas transportation officials said the crack did not appear in the last inspection of the bridge, which occurred in September 2020.”

    except I’ve seen other pictures where there is rust on the ends of the fracture….

    something is wonky here

  12. Yikes! I traveled from Memphis to northern Arkansas, for business, once, but we crossed the Mississippi at the I55 bridge, but I remember seeing it from our crossing.

    Don’t ever look to closely at the bridges in Montreal, get over or under them as fast as you can! That I40 bridge is minty, compared to..

    The scrutinizing eyes of SDA readers are more discerning than public works inspectors, it seems!

    As far as critical infrastructure goes, kids can do their lessons on a computer, you can’t cross the mighty Mississippi with a computer…

  13. I lived in Memphis for 25 years. It seems like the city has around 7 employees in total who aren’t purple suit-wearing slickbacks in Chrysler 300s. They don’t do road repair, animal control, and even the school district is run by the state. It’s Nicaragua with all-night bars.

  14. Every time there is a huge spending bill — remember the porkulus? — the teacher’s unions are at the front of the line. The problem is that fixing actual infrastructure funnels jobs to men, you know, the kind of men who do the actual work it takes to keep the country working. Our new invisible government that is running Joe Biden thinks indoctrination is more important than actual infrastructure so the money goes to the indoctrinators, err… I mean teachers. Why don’t we just start calling infrastructure like bridges “cis-infrastructure”?

  15. Phhht, that’s an easy fix. Just jack it up a little and bolt some more steel across it. Done. Wait, don’t even both jacking it up – just weld it as is.

  16. I came across this post in Airstream Forums that is very interesting. I have no other knowledge about this incident.

    “This is eerily familiar to the closure of the Sherman Minton bridge (I-64) in Louisville back around 2011ish. In fact, the bridge looks to be of similar design and around the same age, possibly also using T1 steel as found on the Sherman Minton. These bridges were found to have issues with using T1 type steel before fracture control plans were created.”

    “T1 steel apparently is very susceptible to this type of cracking and after the discovery on a main support beam on the Sherman Minton, they also found 6 or 7 additional cracks throughout the bridge.”

    “It was believed that the cracking on Sherman Minton was very likely caused by hydrogen that was introduced as the result of improper fabrication procedures of that time period.”

    “The Hernando deSoto crack to me looks more like a complete failure of the section as you can see in the pictures, the beam looks free floating as the sections is no longer aligned or looking connected. ”

    “I would not be surprised as they dig in to it that they find additional cracks and quite possibly do a similar repair as they did on the Sherman Minton where they attached steel plating to both sides. It took 4 months, $20 million dollars to get Sherman Minton back open and I think they also had a second refurbishment campaign on the Sherman Minton that did not require it to be closed.”

    “Either way, the similarities are uncanny.”

  17. With all the fancy stuff we have these days, couldn’t they invent welder robots that crawl around the bridge 24/7 repairing cracks and stress points? Or, just divert all traffic to drive over the far side of the bridge with alternating traffic flows. Failing that, how about a giant jack under the bridge to jack it back up, a five minute job with a stick welder, and Hey Presto, done! 🙂 My degree is from the Groucho Marx School of engineering!
