Paul,

NBI data on Railroad-owned overpass structures is quite unreliable as you have observed. It is possible to use the Google Maps Measure Distance tool (right click to access if using the Google Maps website in your browser). On the highest resolution images you can get within a foot. Even on lower resolution images you can still usually get within 5-10 feet. On my website, I usually add a disclaimer in my description that lengths given are estimates. I know other contributors on BridgeHunter measure railroad bridges like this but I don't think anyone here (to date) notes if they are estimates. Either way, I think the estimates I came up with for this bridge (35 foot span, 100 foot overall) is more accurate than the NBI data.

I went ahead and added the NBI data from 2017 to this page and the page for the Bacon Street overpass for whatever it's worth, though I'm not convinced it's very accurate. For one thing, this bridge is nowhere near 300 feet long, and it's a steel plate girder and stringer combo, not a timber frame structure. Similarly, the Hallett overpass is a through plate girder with stringer side spans, not just a steel stringer.
