I rode 20+ miles today on my usual route. While riding I noticed a problem I haven't ever noticed before. Going north from Jacksonville toward Piedmont, after you pass Federal Mogul and the electrical substation on the left, there are two bridges. On the second bridge I noticed that some of the wood planks are rotten. As I rode over them I could feel them "compress" (the only way I know to describe it) under the weight of my bike. I don't think this is an immediate problem, but one that will soon have to be addressed. If you ride over this bridge be extra careful and slow down.
