1) Suspension bridge has been repaired and is "open for business"!
2) True, a more northeasterly route could have taken some of the edge off the upslope. However, I was looking for shortest bushwhack to reach Davis Path. Didn't find upslope overly daunting, but would've tracked more northeasterly if upslope had been an issue for me.
3) Regarding the forest floor, I don't recall it being overly rocky. Although my recollection is now 7 years old, I recall the footing as being generally good for the vast majority of the route that I followed. Of course, as you likely know with bushwhacking, there is the "50-foot rule", i.e. conditions can vary widely just 50-ft or so on either side of you!
4) You asked for any additional details that I can recall. As I remember it, the more difficult segments of the bushwhack were the first tenth (or so) mile after leaving Dry River Trail, and the last tenth (or so) of a mile before reaching the Davis Path. In both instances, the terrain was steeper and woods were thicker than the overall route.
Hope this helps. Feel free to ask any follow-up questions.
