Rode yesterday, the section from the Hendricks Island parking lot, south to Yardley, 16+ miles. It's all open with no detours.
I just checked with my buddy who lives locally, he states it's ridable from just north of Upper Black Eddy to Yardly, with a short carry detour between Point Pleasant and Lumberville. Completely doable and he's ridden this entire stretch in sections over the past 3 weeks.
Can't state as to north of Upper Black Eddy, but I don't think that section had washouts, which I think was at Paunnacussing Creek where it meets the canal and the river, as Fleecy Dale Rd. was affected and is still not open.
Thanks for the info. Not sure when I'm getting out there, but looking to do a long loop of the NJ and PA sides.
FYI...The NJ side trail doesn't extend all the way to Phillipsburg, NJ. It ends in the middle of nowhere between Frenchtown and Milford. There is an environmental clean up site which prevents the trail from reaching Milford. If you cross into Phillipsburgh you can head south along Main St. At the light immediately after you pass under an old railroad bridge, make a right onto Carpentersville Rd. Climb up to the ridge, bear right, cross I-78 and then head down to the road along the river. It's wonderful back there. At the Roebling Bridge in Riegelsville, NJ, you turn left, cross the RR tracks and then make a quck right onto CR 670. Shortly after you do that, make a right onto Old River Rd. and follow that back to CR 670. Really nice road and you avoid a climb. When Old River Rd. ends at CR 670, make a right an continue heading south.
When you are on the road between Milford and Frenchtown (CR 619), you will see a gravel road on your right. That will take you to the northern end of the NJ trail. You can see it on Google Maps.
If you plan to ride all the way to Easton, I would ride up on the PA side and head south on the NJ side as the climbing on the NJ side is easier going south than it is going north.
