Hundreds Of Structurally Deficient Bridges In Massachusetts: See The Most Traveled

Everyone complains about the bridges they drive over every day. But in Massachusetts, our gripes carry a bit more weight.

Many of the bridges in Massachusetts are classified as structurally deficient or structurally obsolete, according to the National Bridge Inventory Database. (See list below for Massachusetts bridges.)

Of the 5,171 bridges in the state, 483 (9 percent) are "structurally deficient," meaning at least one of the bridge's key elements is in "poor" or worse condition. The Bay State ranks 20th in percentage of structurally deficient bridges and ranks 31st in overall number.

If that isn't bad enough, 2,214 bridges (43 percent) are "functionally obsolete," meaning they do not meet current design standards.

Massachusetts isn't blind to the issue: The state has identified needed repairs on 4,699 bridges, which will cost an estimated $19 billion, according to data from the Federal Highway Administration.

The National Bridge Inventory Database reports federal investment in the state has supported $9.8 billion for capital improvements on 732 bridges between 2005 and 2014.

In the last decade, 274 new bridges have been constructed here, while 190 have had major reconstruction.
