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.
Michael Maltzan is getting into the bridge business. He’s already part of the HNTB-led Sixth Street Bridge team in Los Angeles, he’s finishing up a bridge in Chengdu, China, and parts of his One Santa Fe (which we will profile in a future issue of AN) in the city’s Arts District themselves form a bridge, extending over the ground plane and allowing peeks toward the L.A. River.
Now he’s been tapped by the Hammer Museum to design the John V. Tunney pedestrian bridge, above the institution’s large garden courtyard, finally connecting its 2nd floor western permanent galleries to its eastern ones. Read More
There is an ongoing architectural quest to find new and innovative sustainable materials. Some products could appear in the next science fiction film, such as the fungus-grown packaging material by Ecovative. Other materials have been with us for a long time, under guise of other uses. Some products—like the lowly shipping container—have served one function for so long they beg to be reinvented.
A proposal to turn the old Riverside-Figueroa Bridge into a High Line–style park appears to be dead after a Los Angeles County Superior Court judge declined to issue a temporary restraining order to demolition crews. Introduced by RAC Design Build and EnrichLA last fall, the Figueroa Landbridge would have preserved part of the 1939 bridge for use by pedestrians and cyclists while the replacement span for vehicular traffic was built upstream.

Work was just finished on the Blackfriars Bridge in London, which is now the largest solar bridge in the world. The renovation of the Victorian-era bridge was part of the larger modernization project for the adjoining Blackfriar’s railway station. The station has been fitted with 4,400 photovoltaic panels, which are expected to reduce the station’s CO2 emissions by an estimated 511 tons (563 tons) per year. Work began in spring 2009 and the station was operationally complete in time for the 2012 Olympics, with the solar array installation complete in March 2013. The full refurbishment of the station is now also complete.
The nearly 20,000-square-feet of new panels are intended to offset about 50% of the station’s energy costs.
“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.”
