Back in August 2007, the dangerous and decaying state of America's infrastructure
became a shocking reality when the I-35W Mississippi River Bridge in Minneapolis collapsed, sending vehicles crashing into the river below. 13 people were killed while another 145 were injured. Last August, a bridge collapse in Genoa, Italy, shocked the world with 43 people losing their lives. After that catastrophe, many countries, including the United States, started to seriously look at the state of their deteriorating infrastructure
A new analysis
from the American Road & Transportation Builders Association (ARTBA) has found that over 47,000 bridges in the U.S. are structurally deficient. Placed end-to-end, they would stretch nearly 1,100 miles, from Chicago to Houston. As of 2018, the total repair bill would be an estimated $171 billion.
U.S. drivers cross those bridges 178 million times a day on average and at the current rate, it would take 80 yeas to fix all of them. With a total of 4,675 of them, Iowa has the most structurally deficient bridges, followed by Pennsylvania (3,770) and Oklahoma (2,540).
