Structurally Deficient and Functionally Obsolete Bridges in the Allston-Brighton Area

The Boston Globe ran an article and graphic in today's paper with a map of where bridges classified as "deficient" are located. But you can't really figure out which ones they are referring to, and the Globe provided no list of the bridges themselves to accompany their map.

So I went to the National Bridge Inventory's website, downloaded the Massachusetts data, found those with a "structurally deficient" (STATUS=1) or "functionally obsolete" (STATUS=2) classification, figured out their distance from my house, and output a set of Google Maps URLs for the closest ones to show you where they are.

The closest structurally deficient ones? I-90 turnpike overpass over Brooks Street in Brighton, and the Cambridge Street overpass over the I-90 turnpike in Allston. Many others are classified as "functionally obsolete", although these ones were not described by the Globe article (and may not have structural issues, per se, but could simply be outdated designs).

Oh, and of course, the BU Bridge is labelled as structurally deficient. No surprise: there are big holes in the concrete that you can see through. ("COMB_SOL_FLD_RD_&_RIV_ST_2_BROOKLINE_ST")

Here's the list, where the first column is the distance (in decimal degrees) from my house (note: I have not corrected for the spherical trigonometric projection), and the second column is the average daily traffic across the bridge. Note that some of the latitude and longitude don't quite line up with the maps exactly... but you get the picture. The list is restricted to those carrying at least 3,000 vehicles per day.
