An Up-Close Look at the Monumental Task of Building a Bridge

We take giant manmade structures for granted. Whether erected in decades long gone or constructed anew from a distance, they are just there. When Joseph Blum set out to photograph the building of the new Bay Bridge connecting San Francisco and Oakland, he wanted to get face to face with action bringing such a project… » 2/05/15 9:35am 2/05/15 9:35am

The 5 Most Impressive Infrastructure Projects of the Year

The Plan to Demolish SF's Old Bay Bridge Could Be Derailed By Birds

To us, the bridge is a way to get across the water, but to cormorants in San Francisco Bay, the old Bay Bridge is home sweet home.

The Two-Year Plan To Demolish San Francisco's Old Bay Bridge

It’s been almost a month now since the brand new eastern span of the Bay Bridge officially opened for traffic—24 years and nearly $6.4 billion since 1989’s Loma Prieta earthquake collapsed a section of the original. Now they stand side-by-side, but not for (too) long; a “construction and demolition” plan is underway… » 9/25/13 11:44am 9/25/13 11:44am

It Takes a Ludicrous Amount of Work to Build a Quake-Proof Bridge

Building a road might be harder than you'd think, but we all know that building a bridge is one serious feat of engineering. Here's some proof: 42,000 hours of work time-lapsed down to a hypnotizing 4-minute sprint. » 8/31/13 5:05pm 8/31/13 5:05pm

Art Backers Want to Light Up The Bay Bridge

Compared to the soon-to-be-completed Eastern span, the Bay Bridge's Western length is looking a bit plain. But artist Leo Villareal wants to brighten it up with 25,000 LED's—he just needs $7 million first. » 12/13/11 3:40am 12/13/11 3:40am

The Giant Hunk of Metal That Keeps the Bay Bridge From Slipping Into…

When the Eastern Span of the San Francisco Bay Bridge is replaced in mid-2013, it will be the world's longest self-anchored suspension bridge. To hold the cables that hold the road, crews have just installed a gargantuan 450-ton cable saddle. » 5/24/11 11:30am 5/24/11 11:30am

Why The SF Bridge Broke

SF's Bay Bridge is still closed after a quick repair job fell apart. Terrifying, since my hometown is known for, you know, earthquakes, and this bridge is just falling apart even without them. Here's a pretty good visual/text explanation of what is happening. [sci-experiments via TokyoMango] » 10/30/09 5:23pm 10/30/09 5:23pm
