Interesting area for exploring! Just a reminder that when changing something like that bridge to (the extremely generic) "highway=path", it's nice to explicitly add appropriate access tags (foot=yes, bicycle=yes, etc). The iD interface is slightly confusing in that it shows a default list of (grayed out) assumed values, but unless you click to set them, they aren't actually added, and routing engines have to guess whether it's suitable for any given mode. Surface info is nice, too... bonus points for indicating stuff like wheelchair access or specific barrier types!
