We did okay on it (even loaded down with gear) the one time we had a chance to take it, but didn't even consider it for the return trip. I'd take it again northbound, it's a nice quiet wooded area.
It's the one that follows the railroad tracks. It sounds like the one you are talking about, with railroad ballast. We also had loaded touring bikes and as you mentioned, it's uphill coming from the ferry so it was tough going. I have 32's on my touring bike. It would have been easier with slightly larger tires.
