`  Maybe, maybe not... Projects do not get to set notability guidelines independent of overall notability. If, however, a project comes up with a reasonable yardstick in their specialty area, it ought to be adopted unless there is some overwhelming reason not to. That said... we have for a long time said ``in NRHP == Notability``. Regardless of mention elsewhere, hits, what have you, it's notable, QED. This bridge (if it IS this bridge and not an error, if so, which bridge is it???) has been judged eligible but isn't actually IN NRHP... yet. Just because no one actually did the spadework, presumably. So if something SHOULD be in NRHP but isn't, is it notable by default? Interesting question. One that needs debating somewhere larger scoped than this discussion. (personally I'd tend to say yes but on reflection I admit it's possibly debateable). This bridge, also, if the source is believed, is the 6th oldest steel bridge in MA. ... does that make it notable QED? What if it was the oldest in the world? Certainly, regardless of mention elsewhere. What if it was the oldest in the US? Also certainly. What if it was the oldest in MA? Almost certainly. Where does this line get crossed and inherent end, though? Dunno.  For a state the size of MA, I'd say somewhere lower than 6... at least the oldest 10 qualify... I'd say... ++: / `
