• This week in 1941: Galloping Gertie bridge collapses

    The Tacoma Narrows bridge, known as Galloping Gertie, was a 5,000 ft-long, two-lane suspension bridge — the third longest of its kind in the world; it was the first suspension bridge to use plate girders, rather than open lattice beam trusses, to support the roadbed meaning that wind could not pass through the truss but was diverted above and below the structure; 67 years ago this week the wind was just too strong

  • Canada's crumbling infrastructure reaching critical point

    New study says $200 billion needed to shore up Canada’s infrastructure in order to keep private sector competitive

  • The crisis of U.S. infrastructure, III

    The crisis of U.S. infrastructure is one of political will — the will, that is, to vote for money to maintain this elaborate infrastructure; the true political divide lie between Americans who are willing and able to pay up front for the nation’s needs — whether through taxes or tolls — and those who would rather skimp or burden their children

  • The crisis of U.S. infrastructure, II

    The U.S. infrastructure is elaborate — 4 million miles of roads, 600,000 bridges, 26,000 miles of commercially navigable waterways, 11,000 miles of transit lines, 500 train stations, 300 ports, 19,000 airports, 55,000 community drinking water systems, and 30,000 wastewater plants; maintaining this infrastructure costs money

  • Melting ice menaces Russia's critical infrastructure

    Russian scientists say that the hard permafrost covering the ground year-round across Russia’s far north will melt by 2030; government officials say that if this happens, critical infrastructure, including key airfields, oil storage facilities, and strategic oil reservoirs, could all be destroyed

  • U.K. critical infrastructure vulnerable

    New report says last summer’s flood showed infrastructure’s vulnerability; funding for flood defenses was not sufficient or secure, undermining industry confidence, and there were not enough skilled engineers to deliver the protection from flooding needed

  • Assessing landslide risk

    Researchers develop new technique for assessing areas most at risk from landslides

  • China's transportation vulnerability, I

    China has a long history of rail, airline, and vehicle accidents; outdated or relatively unregulated transportation is a given in many parts of the world, but China has also seen an increase in attacks against transportation targets

  • Thales supplies new signalling system

    London transportation authorities improve control over and monitoring of vast underground rail system by installing improved signalling control from Thales

  • Safeguarding Infrastructure // by Christopher Doyle

    The key to protecting national infrastructure and facilitating lifesaving responses in the event of an incident is preparedness; the Infrastructure and Geophysical Division (IGD) of the Science & Technology (S&T) Directorate at DHS is working to find methods and technologies to improve the ability to protect buildings, facilities, and other kinds of physical structures

  • Potholes wreak havoc on Ontario's infrastructure

    Harsh winters, age, and neglect threaten Ontario’s infrastructure; potholes are created when moisture from rain and thawing snow finds its way into cracks and crevices in road surfaces and then expands during rapid freezes to damage the asphalt; potholes not only hamper traffic, but expose water mains and electrical wires buried beneath roads

  • Sustaining bridge infrastructure through Bridge Information Modeling

    Bentley offers end-to-end bridge solution which will allow bridge engineers to create and renovate bridge infrastructure

  • Unprepared: Canada lacks plan to protect critical infrastructure

    Seven years after 9/11, Canada lacks a coherent, coordinated plan to protect the nation’s critical infrastructure; in a recent report experts dismissed natural disasters, terrorism, cyber attacks, and pandemics as the major threats to Canada; rather, the greatest threat, they said, is a “lack of clarity around governance” during a disaster

  • Simulating hurricanes to test buildings' resilience

    Researchers built a system of “blower boxes” which exert pressure on buildings similar to the buffeting of winds from gusts exceeding 250 kilometers per hour; the goal is to find ways to construct sturdier, more resilient structures

  • Foreign investors vie for Chicago's Midway airport

    The administration has given Chicago the green light to sell Midway airport; six consortiums — five of them involving non-U.S. companies — said they would put in their bids; post-DPW rumblings about non-U.S. ownership of U.S. critical infrastructure are already being heard
