A bridge in Washington State collapsed yesterday after a truck carrying an oversize load hit it, sending cars into the water but thankfully causing no deaths. Images from the scene are, in a word, terrifying.

As of yet, there’s no evidence that the bridge’s structural condition caused the collapse. It was ruled “functionally obsolete” by federal and state inspectors, according to Transportation for America, which has nothing to do with structural integrity. However, the designation can mean, as DC Streets Blog points out, that a bridge “wasn’t built to withstand current vehicle weight loads — or heights.”

Structurally deficient or not, many are likely wondering if bridges in D.C. have similar issues.

According to a new report from the American Society of Civil Engineers, 30 out of 239 bridges in D.C. are structurally deficient. Deficient doesn’t mean that the bridge is unsafe, according to Transportation for America. Rather, the bridge “requires significant maintenance, rehabilitation or replacement.” Deficient bridges must be inspected at least once a year, as opposed to once every four years for bridges in “very good” condition.

The American Society of Civil Engineers says that 155 bridges in D.C. are “functionally obsolete.”

In March, the District Department of Transportation announced that $110 million will be spent to fix the city’s deficient bridges. A request for comment from DDOT about the current state of this project has not been returned.
