Sorry to hear that, really enjoyed that section when we rode from Bethlehem to New Hope a few years ago. But, living near and riding a lot on the C&O Canal Towpath here, canal paths next to rivers are pretty vulnerable - that was a big reason so many of them went defunct! We have detours around damaged spots nearly every year on the C&O, after major hurricane flood damage some detours have lasted for years. I hope the D&L can be repaired faster.
