If a 2+ mile bridge resulted, the  outcome was certainly in error!  
I made 2 edits in ID over two days, one to add a ~60 foot steel/concrete bridge at 45.79662, -122.37414 and the next day to add a ~10 foot wood bridge at 45.79469, -122.36513.  I don't know how a 2+ mile bridge resulted!   I feel confident my edits directly did not create a 2 mile structure, but perhaps a  programmatic handling of the edits I made?  Sorry I did not catch the outcome error myself (which seems to have been reverted as I look at the map now).
