“We got very attracted to the project, and to the idea of making something that reconnects Los Angeles,” Zoltan Pali said of Taylor Yard Bridge, the pedestrian and bicycle bridge designed by his firm, Studio Pali Fekete architects (SPF:a). Originally introduced as part of a mitigations package twenty-two years ago, the bridge, which will span the Los Angeles River between Cypress Park and Elysian Valley, should be completed within two years at a cost of $5.3 million.

With the purpose of conferring the city of Porto, Portugal a new global identity, architects Pedro Bandeira and Pedro Nuno Ramalho have propositioned for the relocation of the Maria Pia Bridge from its original location on the River Douro to the city center. Plans indicate that the bridge’s framework could be easily dismantled and, though it may seem absurd, the proposal comes with a clever solution.

The Swedish Transport Administration launched a conceptual design competition in 2011 for a new bridge in Skuru, Sweden. The competition received great national and international response, including one fanciful proposal by Danish firm, Bjarke Ingels Group (BIG). The competition brief stated that the new bridge should adhere to high aesthetic standards and coincide with the existing bridge and the surrounding valuable cultural and natural landscape. Ingels deploys his characteristic hedonistic sustainability to bring nature onto the bridge itself.

Proving the beauty and sustainable capability of steel construction, the winning projects of the Association of Collegiate Schools of Architecture (ACSA) 2012-2013 Steel Design Student Competition have been announced. The competition, launched last spring, called for comprehensive and environmentally thoughtful steel designs in two categories. The first, Building to Bridge, sought a plan for a long-span pedestrian bridge whose location would be enriched by the connection it created. And the second, Open, allowed for full flexibility in student design ideas of steel construction.

The ACSA chose winners whose projects represented “creative and innovative use of structural steel in the design solution, successful response of the design to its surrounding context, and successful response to basic architectural concepts.”

Heatherwick Studio has envisioned a refreshing way for Londoners to safely commute from the North to the South side of the city that doesn’t involve the hassle of waiting for a bus, squeezing onto the overcrowded “Tube,” or sitting in mind-numbing traffic. The firm, which has been working closely with actress and campaigner Joanna Lumley to develop the design, proposed a pedestrian garden bridge that will extend across the River Thames, providing Londoners with a safe, green river crossing.

After Half A Century, Cincinnati’s Roebling Bridge Welcomes Pedestrians

.

For the first time in half a century, residents of Cincinnati and Covington, Ky. can traverse the Ohio River on foot via Roebling Bridge, thanks to a pedestrian connector reopened June 4. The Roebling Bridge Pedestrian Connector ties Cincinnati’s central riverfront, the site of some major mixed-use development of late, to the city of Covington.

The $430,000 project is part of The Banks’ public infrastructure improvement program. Lane closures will accompany renovations on the north end of the bridge, where a new roundabout and traffic signal will take a few months to complete. Pedestrians, however, can walk on through.

Let’s just hope a certain New York City mayoral candidate doesn’t confuse the Roebling Bridge with its big brother in Brooklyn and snap a photo for his website!

Bridge Over Troubled Freeway: Secretive Bridge In Los Angeles Moving Forward?

Los Angeles’ impressive new bridges have gotten a lot of press lately, including HNTB’s epic 6th Street Viaduct and Andrew Leicester’s unusual so-called basket bridge for the Metro Pasadena Gold Line extension. But one crossing is being worked on in total secrecy: a span over the 101 Freeway at Los Angeles Street, connecting the Civic Center and the Pueblo de Los Angeles.

Artists Jenna Didier and Oliver Hess, who run the city’s Materials and Applications gallery in Silver Lake, are designing the bridge. No renderings have been unveiled, and it’s all very top secret within the city, which is why eavesdrop is on the case. And while Thom Mayne (101 pedestrian bridge) and Asymptote (Steel Cloud) have both failed to make similar ideas happen, this looks like it’s actually moving. Stay tuned.

Waxing Poetic About Chicago’s Wells Street Bridge

Work took place in March to replace a portion of Chicago’s Wells Street bridge—“the engineering equivalent of a heart transplant,” in the words of the Tribune’s Cynthia Dizikes. Work crews replaced a portion of the 91-year old double-decker bascule bridge during just two nine-day periods (a similar replacement in 1996 took almost a year). Inconvenience or not, seeing a 500,000-pound hunk of metal floating into downtown Chicago atop a barge makes one feel like a witness to latter-day Carl Sandburg paeans: “Here is a tall bold slugger set vivid against the little soft cities.”

HNTB’s Squibb Park Pedestrian Bridge connecting the Brooklyn Heights Promenade with Brooklyn Bridge Park opened to the public last Thursday. The $4.9 million bridge was built using “trail bridge technology” with galvanized steel cables and cylindrical black locust timbers, providing an efficient and lightweight structure that, as a sign at the entrance to the bridge warns, quite literally puts a bounce in visitors’ steps. “The bridge is very light weight. You will feel yourself walking across the bridge,” HNTB’s Chief Engineer Ted Zoli said at a construction tour in December. On AN‘s visit to the bridge Friday morning, traversing the spans did in fact provide a bouncy effect.

From the top of San Diego’s soaring 200-foot-tall Coronado Bay Bridge, architect Lew Dominy says you can see Mexico, but outside of special events when the bridge is closed to automobile traffic, pedestrians and bicyclists who might stop to admire the view are prohibited. Dominy, principal at San Diego-based domusstudio architecture, has a plan to build a tube through the distinctive archways of the Coronado’s support piers that would bring multi-modal access to the bridge.

One Year After Dallas’ First Calatrava Bridge, Another On The Way

It’s been nearly a year since the Santiago Calatrava-designed Margaret Hunt Hill Bridge opened in Dallas. Part of an overarching plan to redevelop the banks of the Trinity River, the cable-stayed bridge’s 400-foot-tall central arch pylon has given the Big-D a much-needed civic icon in the otherwise flat and uninhabited swath that the watercourse cuts through the urban fabric.

These photos, taken by budding young photographer Halle Darling-Menking, convey something of the motion and excitement motorists experience while traversing the span. The lines of the cables seem to warp and flex, the arch itself to deflect and lean.

Fans of the crossing now have something more to cheer about. In January, the Dallas City Council approved funding for a second Calatrava-designed bridge across the Trinity, this one expected to cost $115 million. The second bridge, to be known as the Margaret McDermott Bridge, will replace the current Interstate 30 span. It features two arches running parallel to the span supporting pedestrian and bike paths. Construction will begin this spring and completion is expected by May 2017.

When New York’s East River Froze Over

It’s been a mild winter so far in New York, and with the first onset of below-freezing temperatures, city folk are donning their heavy jackets and gloves. And while the winds whipping around the glass and steel towers of Manhattan might feel as if it’s as cold as it’s ever going to be, consider a century ago when temperatures were low enough to freeze the East River from the banks of Brooklyn to the Manhattan waterfront, still two different cities at the time, providing thrill-seeking pedestrians with an instant new crossing years before the Brooklyn Bridge was built.

The above view was engraved in 1871 and titled, “Crossing the East River on the Ice Bridge,” depicting dozens of New Yorkers walking across what would normally have been a busy maritime thoroughfare. While such a natural feat seams unlikely today, Gothamist has collected clippings to show that the phenomenon was known to occur around once a decade on the East River during the 19th century and there have been reports of similar frozen-river bridges along the Mississippi and Ohio Rivers as well. For instance, in 1851, an estimated 15,000 pedestrians, horses, and sleighs crossed the frozen river.
