The Oldest Bridge in New York City Just Reopened After 40 Years

Before the Brooklyn, Manhattan and Williamsburg Bridges, there was High Bridge, arcing far above the Harlem River to connect Manhattan to the Bronx. Originally designed as an aqueduct in 1848, the bridge was closed for the past 40 years until a ribbon-cutting yesterday reopened it to foot traffic. » 6/10/15 6:00pm 6/10/15 6:00pm

The Best Tool for Tracking Our Crumbling Infrastructure Is In Orbit

The sad state of America’s bridges is a perennial topic amongst engineers and a regular talking point for politicians, all of whom have a plan to fix them. An interesting post from the European Space Agency shows how one of the best tools for repair is actually hanging out in Low Earth Orbit. » 5/18/15 11:00am 5/18/15 11:00am

This crazy bridge in Japan looks more like a terrifying roller coaster

If you look straight onto the Eshima Ohashi bridge in Japan, the ridiculously steep incline makes it look more like a roller coaster than a road for cars to drive on. I mean, come on, would you want to drive on that road? It’s basically a highway to outer space, a shortcut to vomiting from nausea. » 5/01/15 8:40pm 5/01/15 8:40pm

No Cars Will Be Allowed on This Stately New Bridge in Portland

It was 1973 the last time a new bridge opened over Portland's Willamette River: a double-decker span with eight lanes of freeway. Times have changed. When the Tilikum Crossing Bridge opens later this year, it will be one of the few in the U.S. that's purpose-built for transit, bikes and pedestrians—no cars allowed. » 3/18/15 7:40pm 3/18/15 7:40pm

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

1 Out of Every 9 Bridges in the US Is Structurally Deficient

There are about 630,000 bridges in the United States, ranging from impressive new structural creations like Margaret Hunt Hill bridge in Dallas to deteriorating slabs of concrete in desperate need repair. It's that last growing group of bridges, ports, and highways that represent the slowing decaying… » 11/25/14 2:32pm 11/25/14 2:32pm

Mad man rides motorcycle over a bridge's arch beam

Bridges to normal humans are things that make life easier because they connect things that, well, don't connect. We get on it and we get to the other side. Bridges to this professional stuntman are obstacles meant for epic stunts, like riding a motorcycle on top of one of the bridge's arch beam! » 10/08/14 11:45pm 10/08/14 11:45pm

Ingenious Design Lowers the Water Under a Bridge to Let Tall Ships Pass

Most bridges are compromises: Cars want to speed low and straight across the water, but but boats want to pass under them. So we wind up with either tall bridges (expensive) or moveable bridges (clunky and awkward). But now a Dutch engineering firm has come up with a radical solution that doesn't involve the… » 9/25/14 4:20pm 9/25/14 4:20pm

A Swarm of Tiny Bots Could Inspect the Hidden Underbellies of Bridges

America's bridges are not—we're sorry to report—doing so great. Of the over 600,000 bridges in the U.S., more than half are over 30 years old, and 11 percent are structurally deficient. That makes inspecting bridges all the more important; unfortunately, the underside of a bridge is also pretty damn inaccessible to… » 9/25/14 1:15pm 9/25/14 1:15pm
