When it opened in 2013, the Squibb Park Bridge that zigzagged between Brooklyn Heights and Brooklyn Bridge Park instantly became one of the most thrilling pieces of the waterfront retreat. The HNTB-designed pedestrian bridge was designed to have some bounce in it, so getting to the park was more than a typical pedestrian experience, it was a fun little adventure. At least for the humans voyaging across it—dogs hated it. The petrified, why-are-you-doing-this-to-me looks on their faces as the wood structure ebbed and flowed were haunting.
A team made up of HNTB (which is also leading the 6th Street Viaduct in Los Angeles), 64North, Bionic Landscape Architecture, and Ned Kahn have won a competition to design a new pedestrian and bicycle bridge spanning the 101 Freeway in Palo Alto at Adobe Creek. The winning proposal for the Adobe Creek Overcrossing, called Confluence, is highlighted by a multi-story, leaning steel arch integrated with an intricate web of cables and floating steel disks.
San Jose Mercury News columnist (and frequent AN contributor) Alan Hess took on HNTB’s Levi’s Stadium, the new $1.3 billion home of the San Francisco 49ers. Hess compares the “starkly utilitarian,” 68,500 seat stadium to Silicon Valley’s high tech environments, and even to its high-end gadgets. The building “translates the high-def experience of a game we see on TV—the roaring crowd, the superhuman action of the players, the intense color of the grass under the TV-studio lighting, the camaraderie of loyal 49ers fans celebrating (or commiserating) en masse—into an enormous three-dimensional architectural spectacle,” Hess wrote.
Are you afraid of taking Rover with you on your next flight because he might have to go potty in the airport? Well, pet-packing passengers flying through San Diego’s Lindbergh Field can rest easy. The airport’s recent $1 billion “Green Build” Terminal 2 expansion includes the nation’s first and only “pet relief” comfort station. Located between gates 46 and 47, the 75-square-foot rest room is decked out with features to get your four-legged friend in the mood to go, including ersatz grass and a fire hydrant. This may be the first, but it won’t be the last. Tom Rossbach, director of aviation architecture at HNTB, told the San Diego Union-Tribune that the firm is offering the amenity to its other airport clients.
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.
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.
We learn from our friends at Curbed that Los Angeles’ Sixth Street Viaduct Competition, replacing one of the most famous—and fragile—landmarks in LA, has a shortlist. The 3,500-foot-long, art deco span was recently deemed beyond repair, and the winner will build a $401 million, cable-stayed bridge in its place. The teams, all present at an LA Bureau of Engineering meeting last night, are AECOM, ARUP, HNTB, Parsons, Parsons Brinckerhoff, and SOM. Three of those teams will present their plans in September, with a winner chosen in October.
