The demolition took place at night in the Chinese city of Wuhan. With 100,000 volt wiring running alongside the viaduct and 30 major gas pipelines underneath it, explosives experts were faced with a task requiring particular precision. The two mile long viaduct was the longest concrete bridge ever demolished in China. — telegraph.co.uk

Crews that built the railing committed what experts called a basic mistake - they welded the bolts in place firmly in their slots rather than leaving a small amount of room to accommodate a natural expansion of the bicycle path that happens in hot weather.

As a result, scores of the 1-inch-diameter bolts have been sheared off along the 1.2-mile bike path on the southern side of the span's skyway section. — sfgate.com

Increasingly it's been cities that have taken the lead on critical issues, from gun control to immigration reform to economic stimulus to climate change. Given the migration of people into cities worldwide, this trend is sure to continue. We might even be in a de facto transition to a society dominated by economically and politically powerful cities — a contemporary version of the great city-states that arose in the 13th century and ruled Europe until the consolidation of modern nation-states. — Places

The modernist five-story glass and steel structure was an attempt by city leaders to shake off the city’s image as a retirement destination. Even more radical was its inverted pyramid shape, chosen by architect William B. Harvard to make the most use of the limited space at the pierhead without blocking views of the city and Tampa Bay. — tbo.com

@bawshaw commented "@LandMass - agreed. although the thesis is interesting, this is not out of the box in terms of a career"...Yet Connely Farr disagreed "@ LandMass - yep. you sound like an ass".

The biggest public transit infrastructure effort in the US is almost completely invisible — unless you’re 160 feet underground. The East Side Access project will connect the Long Island Railroad to New York’s Grand Central Terminal via a massive tunnel under the East River. Actually, that tunnel was the easy part; it was started in 1969. The hard part? “We are building a brand-new railroad here,” says Michael Horodniceanu, president of Metropolitan Transit Authority Capital Construction. — wired.com

More than decade after Abbott's imaginative drawing, Eero Saarinen submitted a design for a gleaming metal curve to a competition, and the saga of the Arch began. Campbell, a history professor and the co-director of the Wendell Ford Public Policy Research Center at the University of Kentucky, joins Scott Simon to talk about the controversy around the design, the African-American residents who were displaced to build the Arch and whether the monument really symbolizes the opening of the West. — npr.org

Frank Gehry has raised concerns that concerts at his Disney Hall in Los Angeles could be ruined by a planned subway line that would run close to the venue.

Recent simulations suggest rumbling might be audible in the concert hall.

These have provoked the architect to call for the Metro’s own noise projections, which two years ago predicted there would be no audible impact, to be reviewed. — bdonline.co.uk

How would the design of the built environment, the process and practice of architecture change if women were leading and equally represented? — indiegogo.com

At $3.74 billion, plus another $200 million in contingencies, the “Transportation Hub” at the World Trade Center—not even the busiest station in the Financial District—will be far and away the most expensive train station built in modern history.

The Hub, as it’s known in Port Authority speak, will be the crowning artistic statement of the World Trade Center complex, perhaps the last grand gesture at a site that was supposed to be full of them. — observer.com

The exhibition at the MAK Center in West Hollywood, curated by UCLA architectural historian and critic Sylvia Lavin, is a wry study of the ways Los Angeles artists and architects worked with, leaned on, stole from and influenced one another in the 1970s.

In a larger sense, it charts the way Southern California architects threw off the influence of establishmen Modernism and helped remake the profession in that decade. — latimes.com
