 I had originally started OSM due to the poor quality of TIGER data.
But looking over the recent upload , it actually looks decent (for the
most part). I think it might be best for the sake of the map to cut my
losses and just go with the tiger data.

 So, in a complete reversal of my previous opinion, would there be a
way to delete all the road data in that bbox that was created by *me*
(roads only, leave the cycle and foot paths) ? We can manually merge
the small amount of data from other users  and fix up the tiger data
where necessary. That might be the best use of everyone's time.
