If you have ever seen the film To Live and Die in L.A. then you know the Gerald Desmond Bridge. It has a starring role in the opening sequence, when Treasury agent Richard Chance (played by William Peterson) bungee jumps off of it. You probably haven’t bungeed off it yourself, but If you’ve ever driven across it, you might get why it needs replacing. The original bridge, according to the project website, “is nearing the end of its intended lifespan.” In fact, the old bridge, while considered safe, is a little scary. Netting has been suspended beneath it to catch pieces of falling concrete. Additionally, its approaches are too steep, it’s too narrow, and perhaps most importantly, the newest container ships can’t fit under it.

New York City Breaks Ground on High Bridge Restoration

Officials broke ground today on the long anticipated restoration of New York’s High Bridge connecting the Bronx with Manhattan. Built in 1848 and today the city’s oldest bridge, the 1,200-foot-long span had long been a popular strolling bridge, even making an appearance in Edith Wharton’s 1913 novel Custom of the Country. The landmarked bridge was closed to the public in the 1970s, but after construction wraps up on the $61 million rehabilitation, strolling New Yorkers and bicyclists can once again cross high above the Harlem River—116 feet—and connect with the city’s growing waterfront Greenway. (See also: Photos of High Bridge before renovation.)

Improvements include pedestrian safety measures like accessibility ramps, viewing platforms, and new lighting. An eight-foot-tall cable mesh fence to prevent jumpers and throwing trash will also line each side, a point that drew criticism from some in the community who believe it’s unnecessary and will spoil views. In a statement released at the groundbreaking ceremony, Mayor Michael Bloomberg called High Bridge “one of our city’s great treasures.” He continued, “It will bring people here from all over the five boroughs, and even all over the world, to see some of the most spectacular views in the city.”

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.

Separated At Birth? Meet the Sixth Street Viaduct’s Mission Impossible Cousin

We could’t help noticing that LA’s new Sixth Street Viaduct, which is being designed by a team led by HNTB, bears a striking resemblance to Dubai’s Meydan Bridge, the royal VIP entrance to the Meydan racetrack where the prestigious Dubai World Cup is held annually. The bridge was featured in the recent film, Mission Impossible: Ghost Protocol, but sits empty for most of the year. Of course there are differences between the two: Meydan’s arches are made of steel, not concrete, it’s not cable-stayed, and its upper arches don’t touch the ground, but they’re still very close in all their wavy glory.

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.

Koons, Meier Among Design Selection Team for Tappan Zee Replacement Bridge

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.

The 3-D laser scan allowed engineers to look at the bridge even after it was dismantled (O.N.E.)

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.

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.
