D.C. plagued by structurally deficient bridges

D.C. is a city of many bridges, and also a city that does not rank high in bridges that are structurally sound.  13% of the District's bridges are "structurally deficient," which amounts to 2,353 bridges.

Some of these are bridges you probably take all the time.  For example, the 9th Street Bridge that crosses I-395 is labeled structurally deficient by Transportation for America.  That bridge was built in 1961 and carries 8,900 cars a day.

The 14th Street Bridge that crosses Outlet Channel, which was built in 1942 and carries 55,700 cars a day was also labeled structurally deficient.

Here is a map of the bridges in D.C., a red icon means the bridge is structurally deficient (click to enlarge).  Though there may be problems with the others as well.   You can get more details on specific bridges here.
