The National Transportation Safety Board is looking for the cause of the horrific collapse of the Florida International University pedestrian bridge collapse on March 15, killing six. people. Angie Schmitt questions why a ped span was needed at all.
A span built to remove the danger of crossing a busy eight-lane roadway to Florida International University became the danger itself when it collapsed five days after being dropped into place using innovative bridge-building techniques.
How did the seven square mile, four-foot high barrier island in the Atlantic Ocean off Miami and Biscayne Bay hold-up to Hurricane Irma? The city arguably has done more to adapt to sea level rise in recent times than any other coastal city.
A city of almost 92,000 people sits on a one-mile wide island designed by nature to protect the mainland from ocean swells, storms, and hurricanes. The seven-mile long island, which floods even when sunny, was spared from catastrophic storm surge.
As Irma leaves the Caribbean and heads for Florida, with landfall expected this weekend, there is a lot to worry about: New building codes will be put to test, fuel to evacuate is in short supply, and cranes have not been dismantled.
