Well then this particular one does indeed seem to be a local specialty. I just did a search through all of the 2012 data that I used to do the road name tiles expansion and there are a total of 586 with "Br" in them. (although I might be under reporting a bit because I combined records that differed only in the TLID field) Interestingly, the same ones also contain a fair number of both abbreviated and expanded directional prefixes in the name field and no directional prefix code.

Like if the way is located in x > county, then Br = Branch else Bridge? In theory it could look for a tiger:county tag. Given the numbers, it might be just as well to punt and flag them for manual review instead of loading the bot up with edge cases. Might be worth running a test to see what it actually does in its current state.
