Bad bridges: Federal data shows US infrastructure crumbling

More than 61,000 bridges throughout the United States are “structurally deficient” and in need of serious repair, a national association of builders has warned, citing government statistics. New analysis of 2014 bridge database information recently released by the US Department of Transportation (US DOT) showed that there were 61,064 “compromised” bridges handling 215 million crossings every day, mostly within the Interstate Highway System.
