Theodore P. Zoli, III is an American structural engineer, and a leading designer of cable-stayed bridges. He is currently the National Bridge Chief Engineer at HNTB Corporation and is a 2009 MacArthur Fellow. [1]
Zoli graduated from Princeton University with a B.S. in 1988 and from the California Institute of Technology with an M.S. in 1989. Since 1990, he has worked for HNTB Corporation. [1] He is a visiting lecturer at Princeton University and Adjunct Professor of Civil Engineering and Engineering Mechanics at Columbia University.
In the aftermath of September 11, 2001, Zoli has focused on the retrofit of bridges across the United States. He developed a novel composite material for lightweight, blast-resistant coverings for a broad array of construction applications [2] stating, “Engineers learn from events, and what 9-11 taught us was that we have to design for unforeseen events; that’s what I’m interested in: designing for things we can’t anticipate.” [3] His blast-resistant bridge work helped earn him the 2009 MacArthur Foundation award. [4]
Zoli designed the new Lake Champlain Bridge connecting New York to Vermont, replacing an older structure and using a unique modified network tied-arch bridge design. [5] Zoli led completion of the design of the Lake Champlain Bridge in an unprecedented 10 weeks in an effort to mitigate community impacts of the prior bridge closing due to structural deterioration of unreinforced piers. The modified network tied-arch bridge design, selected by local public from among five bridge alternatives presented by Zoli, allowed the main span to be constructed off site and lifted into place by barge, accommodating the replacement within two years of closure of the original bridge built in 1929. The project performed permitting, final design, and advertisement all occurring concurrently, coining the term dynamic design/bid/build. The new bridge was opened ty traffic on November 7, 2011 nearly two years after the original bridge was closed. He designed the Squibb Park Bridge, a pedestrian bridge in Brooklyn, which opened in 2013. It was demolished in 2019 due to structural problems and following a lawsuit against his firm. [6] [7]
The Leonard P. ZakimBunker Hill Memorial Bridge is a cable-stayed bridge completed in 2003 across the Charles River in Boston, Massachusetts. It is a replacement for the Charlestown High Bridge, an older truss bridge constructed in the 1950s.
Othmar Hermann Ammann was a Swiss-American civil engineer whose bridge designs include the George Washington Bridge, Verrazzano-Narrows Bridge, and Bayonne Bridge. He also directed the planning and construction of the Lincoln Tunnel.
A footbridge is a bridge designed solely for pedestrians. While the primary meaning for a bridge is a structure which links "two points at a height above the ground", a footbridge can also be a lower structure, such as a boardwalk, that enables pedestrians to cross wet, fragile, or marshy land. Bridges range from stepping stones–possibly the earliest man-made structure to "bridge" water–to elaborate steel structures. Another early bridge would have been simply a fallen tree. In some cases a footbridge can be both functional and artistic.
Salginatobel Bridge is a reinforced concrete arch bridge designed by Swiss civil engineer Robert Maillart. It was constructed across an alpine ravine in the grisonian Prättigau, belonging to the municipality of Schiers, in Switzerland between 1929 and 1930. In 1991, it was declared an International Historic Civil Engineering Landmark, the thirteenth such structure and the first concrete bridge so designated.
The Mezcala Bridge, is a cable-stayed bridge located in the state of Guerrero on Highway 95D in Mexico. It spans the Balsas River close to the western Pacific coast of the country. This bridge, with a total length of 891 m (2,923 ft) and six uneven spans completed in 1993, has been in service since 1994 as a toll bridge.
Chimney Point is a peninsula in the town of Addison, Vermont, which juts into Lake Champlain forming a narrows. It is one of the earliest settled and most strategic sites in the Champlain Valley.
The Champlain Bridge was a 2,184-foot-long (666 m) vehicular bridge in the United States that traversed Lake Champlain between Crown Point, New York and Chimney Point, Vermont. It was opened to traffic in 1929 as a toll bridge; the tolls were removed in 1987. The bridge was closed due to safety concerns on October 16, 2009, and was taken down by explosive demolition on December 28, 2009. It was replaced by a new bridge which opened on November 7, 2011.
HNTB Corporation is an American infrastructure design firm. Founded in 1914 in Kansas City, Missouri, HNTB began with the partnership made by Ernest Emmanuel Howard with the firm Waddell & Harrington, founded in 1907.
TYLin is a global, multi-disciplinary infrastructure services firm. Headquartered in San Francisco, TYLin established its business in the design of long-span bridges and specialty structures.
Kìwekì Point, formerly Nepean Point is a hill overlooking the Ottawa River in Ottawa, Ontario, Canada. It is located between the National Gallery of Canada and Alexandra Bridge. The site is managed by the National Capital Commission (NCC).
The Union Arch Bridge, also called the "Cabin John Bridge", is a historic masonry structure in Cabin John, Maryland. It was designed as part of the Washington Aqueduct. The bridge construction began in 1857 and was completed in 1864. The roadway surface was added later. The bridge was designed by Alfred Landon Rives, and built by the United States Army Corps of Engineers under the direction of Lieutenant Montgomery C. Meigs.
John Ochsendorf is an American educator, structural engineer, and historian of construction; he is a professor in the Department of Architecture and the Department of Civil and Environmental Engineering at the Massachusetts Institute of Technology. He is widely known for becoming a MacArthur Fellow in 2008 He served as the Director of the American Academy in Rome from 2017 to 2020. In 2022, he was appointed the founding director of the newly created MIT Morningside Academy for Design.
The Lake Champlain Bridge is a vehicular bridge traversing Lake Champlain between Crown Point, New York and Chimney Point, Vermont. It replaced an older bridge that was demolished in 2009. The bridge was designed and constructed during an aggressive two-year schedule to minimize the social and economic impact of the original bridge's demolition. It is the only fixed-link crossing of Lake Champlain/Champlain canal between US 4 in Whitehall, 42 miles (68 km) to the south and US 2 at Rouses Point, 85 miles (137 km) to the north.
Certain works of structural engineering design are also works of structural art. Such works can be classified as structural art when they attain excellence in the three areas of efficiency, economy, and elegance, as defined by Prof. David P. Billington of Princeton University. A key part of the concept of structural art is that the structural engineer making the design must exercise his or her creativity and playfulness to create an elegant structure within the constraints imposed by engineering requirements. These constraints include the safety and serviceability of the structure. Therefore, a structure cannot be a successful work of structural art without also being a successful work of structural engineering design, yet many works of structural engineering design that are safe and serviceable do not rise to the level of structural art because they fail to be economical, efficient, or elegant. Structural art is a topic of active scholarly research at several universities in the United States, including Princeton University, Tufts University, Bucknell University, University of Massachusetts Amherst, the Massachusetts Institute of Technology, and Roger Williams University, and in other parts of the world such as Spain and Germany. While structural artists often collaborate with architects, the discipline of structural art is based upon engineering rather than architectural design. A recent summary about this topic can be found in a review paper.
