Gephyrophobia is an anxiety disorder characterized by a fear of bridges. No not those bridges. If you suffer from this disorder (as I do) you may not want to read this list of bridge collapses. You may also not want to read that the US Department of Transportation rates 1 out of 9 bridges in the country as deficient. Even worse, here's an awesome interactive map showing your local bridge evaluation scores from the USDOT.
Could you roller skate across this bridge? It's 300 meters long and 180 meters above the ground, and the entire bridge floor is made of glass.

The last remaining Inca rope bridge is the Q'eswachaka, spanning the Apurimac River in Peru. Even though there is a modern bridge nearby, the residents of the region keep the ancient tradition and skills alive by renewing the bridge annually, in June. Several family groups have each prepared a number of grass-ropes to be formed into cables at the site, others prepare mats for decking, and the reconstruction is a communal effort. In 2009 the government recognized the bridge and its maintenance as part of the cultural heritage of Peru.
Amsterdam is planning out a new steel canal bridge that will be constructed entirely by 3D Printers. Here's a video of these special printers in action.
The length of the cables was absolutely critical, because the water does not forgive the slightest error, as it always flows to the lowest point, increasing the error and making the system unstable. The next challenge was to find a way to make the rappelling (abseiling) and climbing up the rope as easy as possible and absolutely safe, with at all moments two independent safety lines, well protected from the friction on the concrete bridge.
In an effort to not favor any of its member countries over the others, the European Central Bank decided to feature fictional bridges on a series of banknotes. So the Dutch built the bridges.

A few months ago there was a list of links to classic video game emulators posted. Very recently, I'm pleased to report, those links all came true. The Internet Archive bespoke upon aforementioned consoles, computers, and mileposts on our way to the tech utopia of today, (seriously, where's my flying car?) and they asked us to do something: Imagine every computer that ever existed, literally, in your browser. And it was so. I have absolutely no affiliation with jscott, btw. Thought I should disclose that.

The Jumper Squad. "Each year, the New York City Police Department receives hundreds of 911 calls for so-called jumper jobs, or reports of people on bridges and rooftops threatening to jump. The department’s Emergency Service Unit responds to those calls. Roughly 300 officers in the unit are specially trained in suicide rescue, the delicate art of saving people from themselves; they know just what to say and, perhaps more important, what not to say."

Today is the 202nd birthday of Isambard Kingdom Brunel, one of the world's greatest engineers and a personal hero. I gaped at the Clifton Suspension Bridge in Bristol when the shock of recognition dawned on my jetlagged brain. This was the man that laid the foundation for Britain's global economic might, built the first underwater tunnel, Paddington Station and inspired engineers everywhere. His legacy lives on in his works, a university, a museum or two among others.

Deliberately turning her camera from the wreckage, That Red Girl gives us a look at what's going on in her now quarantined life mere blocks from the recent Minneapolitan bridge collapse.
"Several neighbors and I stood in our driveway late into the night debriefing the day. We now live in lockdown. Police must escort us around. We must meet any guests at the corner, they cannot approach the building alone. Residents are told to ask people they do not recognize to show their keys and prove themselves. We joke about seeing everyone’s “FOBs” to those we know well. The dogs are all leashed, tying themselves together as they try to play like normal. It’s frustrating to everyone that we can’t run around as normal. The word “quarantine” is tossed around. People are nervous. One of the residents hasn’t been seen since Wednesday morning. She may be on vacation… no one knows. We see one of the neighbors being interviewed on the corner and a few young girls trying to flirt with the police to gain entrance to our complex. The dogs continued to wrestle and we continued to talk."
