Santiago Calatrava has topped out on his second Dallas bridge - the Margaret McDermott Bridge - two years after completing the Margaret Hunt Hill Bridge. The steel arch, reaching a height of 275 feet, is the first of two that will support the 1311-foot-long bridge that is intended to provide access to pedestrians, bicyclists and cars over the Trinity River. The $113 million bridge is part of the massive $798 million Dallas Horseshoe Project that aims to alleviate traffic and enhance accessibility downtown. It is scheduled to complete by the summer of 2017.
China will soon finish construction on what will be the world’s tallest and longest glass pedestrian bridge, floating 300 meters above a canyon in the Zhangjiajie National Park. Designed by Israeli architect, Haim Dotan, the Zhangjiajie Grand Canyon Glass Bridge will be 380 meters long, six meters wide and feature a transparent glass floor.
Did you know that the fictional bridges on the Euro banknotes were actually made a reality in the Netherlands? In Tom Scott’s latest “Things You Might Not Know” video, he tells the story of how the seven bridges came to be constructed in the town of Spijkenisse.
The winners of the Atlanta Bridgescape Competition were announced today at the American Institute of Architects' (AIA) National Convention. The urban design challenge sought proposals for creative interventions at two existing freeway overpasses in the city’s Midtown and Downtown districts, with a referential budget of $3 million per bridge. The winners were selected from five finalists by a panel of industry experts.

The world’s longest glass skywalk has been inaugurated in China, jutting off the edge of a 718-meter tall cliff in the Longgang National Geological Park in Chongqing, reports CCTV. Aptly named Yuanduan, which means “at the end of the clouds,” the horseshoe-shaped walkway offers visitors stunning (and a bit terrifying) views of the surrounding mountains and canyon below. Extending for more than 26 meters off the cliff’s edge, the bridge is five meters longer than the Grand Canyon Skywalk. Only 30 tourists will be allowed on the bridge at a time.

New images of Thomas Heatherwick's recently approved Garden Bridge depicts how it will look once built in 2018. With 270 trees, 2,000 shrubs, hedging plants and climbers, over 22,000 perennials, ferns and grasses and 64,000 bulbs planted on the bridge, the lush river crossing will take pedestrians through London's horticultural history, "from wild marshland to cultivated gardens," as the Garden Bridge Trust reports. Five distinct landscaped areas, created by landscape designer Dan Pearson, will span the bridge's 6000 square-meters of open space and represent the capital city's plant cultivation from centuries past.
Five finalists have emerged in the Atlanta Bridgescape Competition.

Students from Eindhoven University of Technology (TU/e) will attempt to beat the world-record for the longest open span attained by an ice structure by constructing an ice bridge inspired by Leonardo da Vinci. Following a yearly tradition of exhibiting architecture made from ice, the bridge is anticipated to span an astounding 50 meters. If the team succeeds, they will shatter the school's previous record set in 2014 when students built an ice dome spanning 30 meters.

The Hubei United Investment Group (HUIG) has commissioned Santiago Calatrava to design three major highway and pedestrian bridges in the AECOM-masterplanned city of Huashan, 12 miles east of downtown Wuhan. The bridges will be Calatrava's first project in China. They will span a new man-made canal that bisects Huashan's urban center and connects two lakes that feed the Yangtze River.
“It gives me great personal satisfaction and represents a grand challenge that I face with great enthusiasm to help develop this ambitious project that enables me to design my first bridges in the Far East," says Calatrava.
The City of Gothenburg has commissioned Erik Andersson Architects to design a new pedestrian bridge in the city's historic Haga district. The circular bridge, connecting streets Haga Kyrkogata and Arkitektgatan, will be made of carbon fiber, allowing for a narrow profile that seemingly floats over the water. It is envisioned that the landscape the crosses inside the circular form can be used as an amphitheater for riverside performances.
Four teams including Hopkins Architects, Amanda Levete's practice AL_A and two separate teams from Ove Arup & Partners have been shortlisted in the competition to design a new bridge in London spanning the Thames from Nine Elms to Westminster. The competition for the £40 million bridge, part of the dramatic new developments at Nine Elms and Battersea, made headlines last month when all 74 entrants were released to the public.
Read on after the break to see the entries from all four teams
The recent unveiling of the 74 entries to the Nine Elms to Pimlico Bridge competition was undoubtedly intended to cause a media circus, hoping to emulate the furore that surrounded the much larger Helsinki Guggenheim competition when they released all 1,715 of their entries to the web in October of last year. The competition, which asked designers to propose "one of the most expressive and visible landmarks in London," is the latest in a series of dramatic changes taking place on this stretch of the South Bank of the Thames. This new community, one of London’s most prestigious new neighbourhoods, includes Keiran Timberlake's new US Embassy and a slew of residential developments, culminating in the highly-touted renovation of Battersea Power Station, complete with accompanying buildings by Foster + Partners and Frank Gehry, and a public space by BIG.
Initial reactions to the competition entries has been mixed at best. The Guardian’s architecture critic Oliver Wainwright took the opportunity to poke light-hearted fun at a selection of designs, using his considerable powers of wordplay to dub entries with titles such as The Greenhouse Funhouse, The Spaffy Tangle, Razorwire Party Bridge, and The Flaming Mouth of Hades. Similarly, City Metric ran the news with an article titled “The 12 Most Ridiculous Designs for the New Battersea Bridge”, sparking a debate on Reddit in which users branded the projects "varying degrees of insane" and "ridiculous doodles." But beyond all this jovial name-calling, these designs are symptomatic of an unhealthy approach to wealth that London seems unable (or perhaps unwilling) to address.
All 74 “wild designs” being considered to become London’s next “landmark” have been released to the public. As part of a two-stage competition, architects worldwide have submitted ideas for a new £40 million pedestrian and cycle bridge that will connect London’s Nine Elms and Pimlico communities over the River Thames.
The jury, chaired by Graham Stirk of Rogers Stirk Harbour, will choose four schemes to move onto the competition’s second and final round in March. These designs will be then shortlisted and further developed with input by the community and client before a winner is announced in July.

Arup have released a new image of the proposed copper-nickel alloy cladding that will adorn Heatherwick Studio's Garden Bridge in London. According to a report by the Architects' Journal, the "concrete structure will be coated in 'cupro-nickel', from its feet on the riverbed up to the base of the balustrades on the bridge deck." The copper will be donated from Glencore, a multi-national mining company, forming "a protective skin to the carbon steel structure giving it a maintenance free 120-year life, protecting the bridge from river and environmental corrosion." More than 240 tonnes of the metal alloy, which often finds use in medical equipment and ship propellers, will be used.
64 North, HNTB Engineering, Bionic Landscape Architecture and sculptor Ned Kahn have been chosen by the City of Palo Alto to realized a new bicycle and pedestrian bridge over the 14-lane Highway 101 at Adobe Creek. Their winning proposal, “Confluence” will connect residential and commercial areas in south Palo Alto to the Baylands Nature Preserve and the regional Bay Trail network.

London based firm McDowell+Benedetti has recently announced that their design for a new 180 metre footbridge and improved rail station in Terni, Italy, has begun work on the site. A future landmark for the town, the £3.5 million (€4.4 million) project promises to provide an expanded commuter hub for the area with connections to fast trains to Rome. Learn more about this project after the break.
Wandsworth Council has announced that it plans to hold an international design competition for a new pedestrian and cylist bridge across the Thames, connecting Nine Elms on the South of the river to Pimlico on the North. The announcement comes in response to a feasibility study by Transport for London which concluded that a bridge at this location could handle around 9,000 walkers and 9,000 cyclists a day at a construction cost of £40 million.

"Nearly half of London’s population lives east of Tower Bridge yet they are served by only two fixed road river crossings," says Colin Stanbridge, Chief Executive of London Chamber of Commerce and Industry (LCCI). This is the infrastructural predicament which has sparked the LCCI's "Bridge East London" campaign, a proposal for bridge linking Beckton and Thamesmead at Gallions Reach, which is aided by a design by HOK.
The proposal was unveiled on Monday, the 120th anniversary of the opening of Tower Bridge. Designed to allow clear passage for both ships underneath and aircraft taking off or landing at City Airport above, the bridge also features a segregated cycle path, adding a much needed - and entirely safe - river crossing for London's growing number of cyclists.
