Pylons here have orange and blue blazes on them, and the capital letter H. Bass River SF is not supposed to have any marked trails, so what do these correspond to?

Is the Knox & Kane Rail Trail detour still in place here? Is the trail under construction from here north? Any segment under construction should maybe be re/tagged as construction=yes or all/access=no.

Greenfield striped unprotected bike lanes on 43rd between Howard and Cold Spring, but City of Milwaukee owns 43rd north of Howard. Has Milwaukee striped bike lanes to fill this gap between Morgan and Howard?

Did Howard get new unprotected bike lanes in the area of 51st?

What's the current state of this road? Is it passable by car or by foot?

Does this bridge still exist in 2025?
