While I am reasonably certain this is true in the USA, I don't believe that 
makes it necessarily false elsewhere.  Not to start an argument, but I'd be 
curious to know if a "fact" (about a closed section of roadway) falls under 
Australia's "Part III Works" (of copyright law there) of literary, artistic, 
musical and dramatic works, or "Part IV Subject Matter" (e.g. sound recordings, 
films, broadcasts...).  It would seem to be "neither" (and leaving Australian 
copyright law with nothing to apply to), but I'm happy to be enlightened 
otherwise.  Bob simply asks whether what he knows about a closed section of 
roadway going into OSM is a violation of ODbL.  Questions of "where did the 
knowledge of this come from?" are valid to ask, but when the answer is "direct, 
personal observation," what is copyright-able?

Any copyright law which claims that publishing (or re-publishing) straight 
facts is a violation of law needs to be examined in the light of what OSM 
Contributors do all day long:  which is to put facts about the real world into 
a geospatial database.  We're in real trouble if we can't do that.  The 
corollary is that I don't think we're in real trouble.

Again, it all seems to come down to "how did you learn about that?"  If it was 
a government-published (maybe Crown Copyright holds, I wouldn't be surprised if 
it does) radio-disseminated Livetraffic broadcast (and again, for various 
reasons, that could go either way), I'd be wary of entering it (in Australia, 
but in USA, if published by federal gov't, it's automatically in the public 
domain; the fifty states vary somewhat but I'd say a trend is for "open data" 
or "sunshine" laws to apply and make it "freely" available).

However, if it is Bob traveling to both sides of the closure, observing signs 
and concluding that such "facts" are directly observable truths in the real 
world, I'd offer him my two thumbs up to putting those data into OSM with 
little or no worry.

If Bob heard a radio broadcast and those data fell under copyright for some 
reason, or he knows they were derived and/or explicitly Google Maps data, well, 
"not."  But if he ALSO made the drive noted above, he can "mentally subtract" 
the radio/Google slap-that-might-say-don't and ignore those, allowing his 
"personal observations" to supersede.  And maybe he even enters "personal 
observation" as the source of the data in his changeset comments as he does.  
(I've done that, and I'm proud when I do).

(OK, that WAS kind of lengthy).
