The expansion of LA’s Metro Rail Gold Line is well underway with a stunning new piece of infrastructure: The Gold Line Bridge. Completed last week, the 584-foot dual-track bridge, stretching over the eastbound lanes of the I-210 Freeway, will provide a light rail connection between the existing Sierra Madre Villa Station in Pasadena and Azusa’s future Arcadia Station. The rail line itself is scheduled for completion in 2014.
Made from steel reinforced concrete with added quartz, mica crystals, and mirrored glass, the monochromatic, abstract design, conceived by artist Andrew Leicester, pays homage to the region’s historic American Indian basket-weaving tradition and includes a carriageway and a post-and-lintel support beam system. The 25-foot baskets adorning each of the posts, “metaphorically represent the Native Americans of the region…and pay tribute to the iconic sculptural traditions of Route 66,” wrote Leicester.
Before the end of this year, the Squibb Park Pedestrian Bridge will be completed connecting Brooklyn Heights with the Brooklyn Bridge Park on the waterfront. This windy path over the BQE and through the treetops will quite literally bridge the divide and substantial grade shift between the neighborhood and the park. Construction of this $4.9 million pedestrian bridge, made of black locust timber and galvanized steel, is already underway, and on December 14th and 15th, the spans will be hoisted into place over Furman Street.
In September, AN reported on the three proposals to replace Los Angeles’ iconic but crumbling Sixth Street Viaduct by HNTB, AECOM, and Parsons Brinckerhoff. The three teams have notably added pedestrian amenities and adjacent lush landscaping to the 3,500-foot-long cable-stayed span. While the renderings were compelling for each design, these video renderings fly the viewer in and around each proposal for a more detail view of what might soon be built in LA. Take a look.
Jeffery Koons, perhaps best known for his quirky stainless steel glossy sculptural reproductions of balloon dogs, has been called upon by Governor Andrew Cuomo to help decide what the new Tappan Zee bridge will look like. Koons, along with Richard Meier, winner of the Pritzker Prize for Architecture, and Thomas Campbell, Metropolitan Museum of Art Director, were named to the selection design team that will provide counsel on the construction of the Tappan Zee replacement bridge. Governor Andrew Cuomo announced the decision in a press conference Wednesday. Meier’s most notable work includes the Getty Center in Los Angeles, the Barcelona Museum of Contemporary Art and the Jubilee Church in Rome. The design team will offer advice on the bridge’s aesthetics and visual compatibility with the surrounding nature.
There’s a scene in Edith Wharton’s 1913 novel Custom of the Country, where the wicked vixen Undine Spragg insists on speeding across the High Bridge in a “horseless carriage” before making her grand entrance at a party so as to rouge her cheeks with a cold snap of air whipping up from the Harlem River. The romantic fascination accorded the then-65-year-old bridge quietly slipped from New York’s consciousness as bigger engineering marvels usurped its quiet dignity.
Now approaching 165 years, renovations are about to get underway to finally restore the bridge to its former glory as a 1,200-foot-long pedestrian bridge, uniting neighborhoods of High Bridge and Washington Heights in the Bronx and Manhattan. New Yorkers for Parks stopped by the span Monday afternoon to document current conditions before construction is in full swing, giving us a hint of Undine’s views. Though controversial netting integrated into the design might mildly disrupt the vista, Monday’s photos show it the way it was, albeit slightly overgrown.

Laser scanning technology helped a Minnesota bridge find its third home
One of 24 historic bridges chosen for preservation by the Minnesota Department of Transportation, Bridge 5721 is one of the state’s only remaining wrought iron bridge structures. The bridge was originally built to carry pedestrians over a river in Sauk Center, Minnesota, in 1870, before modern steel production methods had become available. In 1937, the bridge was disassembled and moved to span the Little Fork River near the town of Silverdale. But more than two years ago, the structure began its journey to a third incarnation, this time as an equestrian and pedestrian bridge for the Gateway Trail in the town of Stillwater, near Minneapolis. Because of the bridge’s provenance and the desire to keep its wrought iron parts intact, the Minnesota DOT worked with new owner Minnesota Department of Natural Resources and structural engineers at HNTB and Olson & Nesvold Engineers (O.N.E.) to collect crucial data for the rehabilitation using new 3-D laser scanning technology.

Last night, the AIA SF launched a new exhibition, Architecture of Consequence: San Francisco, kicking off a whole slew of events in its annual Architecture in the City Festival, the country’s biggest such celebration of the built environment. The exhibit explores important social needs that architects can address and features the work of four San Francisco firms—Iwamoto Scott Architecture, Fletcher Studio, SOM, and Envelope A+D—side-by-side with four Dutch firms—Van Bergen Kolpa Architecten, 2012 Architecten, ZUS (Zones Humaines Sensibles), and OMA.
The 17th-century Sospiri Bridge (Bridge of Signs) in Venice connects an ancient prison with interrogation rooms in the Doge’s Palace. The bridge crosses the Rio de Palazzo that itself slices through the palace and makes a spectacular vista as one crosses the canal bridge on the Grand Canal. This vista has been rudely emblazed for at least the past five years by a giant advertising sign the wraps the palace walls and over and under the beautiful Sospiri bridge.
Construction continues at Santiago Calatrava‘s bold Margaret Hunt Hill Bridge in Dallas after it’s signature arch was topped off in June. The cable-stayed bridge is one of three planned as part of the Trinity River Corridor Project, which aims to redevelop the Trinity River and its floodplains, improving traffic flow, increasing parkland, and providing flood protection for the region.
