11 Deeply Alarming Facts About America’s Crumbling Infrastructure
http://theeconomiccollapseblog.com/archives/11-deeply-alarming-facts-about-americas-crumbling-infrastructure
#1 According to the American Road and Transportation Builders Association,
nearly 56,000 bridges in the United States are currently “structurally
deficient”. What makes that number even more chilling is the fact that
vehicles cross those bridges a total of 185 million times a day.
#2 More than one out of every four bridges in the United States is more than
50 years old and “have never had major reconstruction work”.
#3 America does not have a single airport that is considered to be in the
top 25 in the world.
#4 The average age of America’s dams is now 52 years.
#5 Not too long ago, the American Society of Civil Engineers gave the
condition of America’s dams a “D” grade.
#6 Overall, the American Society of Civil Engineers said that the condition
of America’s infrastructure as a whole only gets a “D+” grade.
#7 Congestion on our highways costs Americans approximately 101 billion
dollars a year in wasted fuel and time.
#8 According to the U.S. Department of Transportation, over two-thirds of
our roads are “in dire need of repair or upgrades”.
#9 In order to completely fix all of our roads and bridges, it would take
approximately 808 billion dollars.
#10 Federal spending on infrastructure has decreased by 9 percent over the
past decade.
#11 According to Bloomberg, it is being projected “that by 2025, shortfalls
in infrastructure investment will subtract as much as $3.9 trillion from U.
S. gross domestic product.”
The quality of our infrastructure affects all of our lives every single day.
For instance, we all simply take it for granted that safe, clean drinking
water is going to come out of our taps, but recent events have shown that is
not necessarily always going to be the case. | y********l
