They took down the turnpike bridge after I completed the trail in June 2009. You can simply go downhill on one side and cross under through the culvert.
I completed the 70 miles in 5 days of hiking but wasted several more miles trying to get to a pizza parlor in the ski resort (Closed weekdays) advertized in backpacker magazine. They were still doing a lot of construction on the mountain top villiage around the ski pond.
The shelters were nice although a little too far from the trail. Stone fireplace with steel swinging grates. Bring a ground cover because there are wide spaces between the floor boards. You easily loose a lighter through the cracks. Evidence of mice in the Adirondack style shelters. Water is sporadic at the shelters, hand pumps, some wells are closed off. Firewood supplied, mine was poplar wood that produces too much smoke.
If I was to do it again, I would simply ignore the shelters and steath camp a couple hundred yards off the trail. Mainly because of the extra 1/2 to 3/4 mile off trail shelters but also due to the distance between the shelters. I could better regulate the daily distance.
The trial was manicured the first half but not so on the second half (past the resort)
