The American Road & Transportation Builders Association’s 2024 Bridge Report survey has found 221,800 bridges in need of repair and 76,175 bridges that should be replaced across the country. The accounting, released in late August, claims that some 36%—or nearly 221,800 spans—require... View full entry
The U.S. Department of Transportation announced that more than $5 billion in grant awards will be used to repair or replace nationally significant large bridges across the United States. The money is being delivered via Large Bridge Project awards through the Federal Highway... View full entry
A team of researchers from Japan’s Tohoku University has developed a new mechanoluminescent construction material they say can be used in infrastructure to monitor daily use stress information in real-time in order to avert potential future catastrophes that may result from its aging stock of...

"A lot goes into how that reconstruction will be designed, how the process is going to work," Buttigieg said on "Face the Nation" on Sunday. He noted that he didn't have an estimate on the rebuilding timeline, but the bridge itself took five years to initially construct. "Right now we don't fully know everything we need to know about the condition of the portions of the bridge that did not collapse." — CBS 'Face the Nation'
Engineering News-Record reported that debris removal has already begun in haste at Baltimore's Francis Scott Key Bridge collapse site, where six people lost their lives last Tuesday, courtesy of the U.S. Navy, Army Corps of Engineers, and Coast Guard. The surviving portions of the bridge will... View full entry
Today is World Engineering Day, and to celebrate it, Archinect has curated a few outstanding bridge projects we’ve included in our recent news coverage to highlight critical pieces of infrastructure at an important time for civil and structural engineering in the Americas and abroad. The six... View full entry
A study of every bridge in the U.S. Department of Transportation database has discovered a need for $319 billion worth of major repairs or replacement work on a total of 222,000 spans across the country. The findings published in the American Road & Transportation Builders Association’s... View full entry

In a new paper published in Nature Materials, the researchers showed that the diagonally-reinforced square lattice-like skeletal structure of Euplectella aspergillum, a deep-water marine sponge, has a higher strength-to-weight ratio than the traditional lattice designs that have used for centuries in the construction of buildings and bridges. — Harvard School of Engineering and Applied Sciences (SEAS)
Matheus Fernandes, a graduate student at the Harvard John A. Paulson School of Engineering and Applied Sciences said in a statement: "We found that the sponge's diagonal reinforcement strategy achieves the highest buckling resistance for a given amount of material, which means that we can build...

The NYU Tandon School of Engineering, T.Y. Lin International, and Sam Schwartz Engineering have unveiled a proposal for a new bridge connecting Queens and Manhattan. The so-called "Queens Ribbon" proposal is part of a larger set of pedestrian and bicycle bridges proposed by the design... View full entry
A design team led by the Office for Metropolitan Architecture (OMA), landscape architects OLIN, and structural engineers WRA has completed preliminary plans for the new 11th Street Bridge Park in Washington, D.C.

Demand for routine bridge inspections is expected to rise four times its current level to reach a market valuation of $6.3 billion by the end of 2029, according to research firm Fact.MR. A push for infrastructure modernization in the Asia-Pacific region the largest share of the market at 35%. — Construction Dive
According to Construction Dive, the need for more bridge inspections will be driven by a combination of aging infrastructure, exposure to damaging environmental conditions, and an increase in traffic volume, all of which speed up the deterioration of bridges. This is expected to raise... View full entry
Researchers at MIT have proven Leonardo da Vinci correct yet again, this time involving his design for what would have been at the time a revolutionary bridge design. Although clients rejected da Vinci's work at the time, over 500 years later, the researchers have proven that his bridge would have worked. — Popular Mechanics
Part of a proposal for Sultan Bayezid II of the Ottoman Empire, da Vinci's bridge was intended to connect what is now Istanbul to Galata, a neighboring city. The proposed design spanned about 918 feet and was of masonry construction, making use of the compressive characteristics of an arc... View full entry
The sweeping structure, which spans the Grand Canal and was the first new bridge to be built in the floating city for 70 years, was designed by renowned Spanish architect Santiago Calatrava.
But it has been dogged by controversy ever since it was unveiled in 2008.
— The Telegraph
According to The Telegraph, Santiago Calatrava has been fined €78,000, or roughly $86,000, by the city of Venice due to "negligence" involved in the design of the troubled 300-foot-long Ponte della Constituzione bridge in the city. According to the report, an Italian judge... View full entry
