I happened to respond on this when the call came out around 2AM. It was a long 12 hours. I never expected B1M would do a video on it, but glad they did. It truly was a surreal event

[amechanicalengineer]

The effect on traffic is definitely noticeable. The tunnels under the harbor get clogged up way more frequently and hazmat have to go all the way around the city on the other side of 695. Weird to see your house in a B1M video...

[user]

I’m going to go out on a limb here and say that your title is the understatement in engineering history. As a ship knocking into a support pillar, resulting in the bridge collapsing, was not supposed to happen.

[nah]

2:34 116, 000 tons is the weight of what the ship can carry and not the weight of the actual ship. It's called Dead Weight Tonnage.

The actual weight is the displacement which in this case was almost 149, 000 tons.

I drove on it the day before it collapse to go home and the next morning it was gone. It was kind of surreal. Now the alternative routes are the two tunnels and the other side of the ring 695 highway. But it's already busy before with the Washington DC metro traffic. We definitely need better public transportation to relieve car dependency

[a-_-s]

11:02 pffft “lessons will have definitely been learned” oh how you underestimate our ability to avoid learning any lessons 😂

[pacldawson]

I live near Baltimore Harbor, and when my wife asked what the new bridge design would look like, I said it should be a cable-stayed bridge... for the reasons you cover here in this video.

[marsgal]

I live in a town that recently lost a bridge (Red Bridge, Kamloops). Not because a ship hit it, but because somebody set its mostly-wood structure on fire. It wasn't a huge bridge, but it was a strategic part of the city's road network. Like Baltimore, it's going to be a while before they rebuild it...

[ohheyitskevinc]

The wake up call for the US was in 1980 with the Sunshine Skyway Bridge collision and collapse. Oddly, the response was to learn lessons only for that bridge’s replacement. No other bridges. The Golden Gate and bay bridges in SF are just as exposed right this minute.

[wheely]

monday upload!? what a great start to the week!

[scottya]

Born and raised in Baltimore. The bridge opened the year before I was born, so it has literally been a fixture on the landscape all my life. It is just so weird to drive around and not see it anymore… The only thing left or the approaches just kind of hanging out and going nowhere.

[tsundear]

It’s still so weird driving by and just seeing two on-ramps to nowhere

[jerrysstories]

When you said “...lessons will have definitely been learned...” I heard a great chorus of voices saying, "Hold my beer."

[atomosk]

Nothing like a Monday B1M upload to get the week started right

[MarloSoBalJr]

A lot of progress is being made quickly in the planning stages, but... like many things here in Maryland, I'll believe it once it's finished.

[aerotheepic]

0:49 Idk why but they way you said Maryland is funny to me "merry-land" lmfaoo

[QueenetBowie]

1.7 billion estimated cost for a us infrastructure project usually means 5 billion dollars in end costs.

[gregboi]

8:40 those estimates will undoubtedly double, this is civil contracting we're talking about

[jokerace]

About 60 seconds of looking at it on G Earth, it became pretty obvious that bridge needed much more collision protection built around the main supports.

[nelsn]

I remember when everyone on the internet were suddenly bridge engineers and now they’re “meteorologists”. Time flies so fast.
