Currently, the detour is almost exactly 0.2 mile. Much of the surface is packed, but there is loose gravel in places. I had to slow down on my road bike to avoid spilling, but a mountain bike would have no trouble. It was dry when I rode over the detour today; it is going to be a mess when it rains. At least 1/2 mile of the W&OD needs to be shored up. I am not how the work is going to proceed: will they finish the current segment, reopen the W&OD there, then start a new segment? Or, are they going to close more of the trail and work on the whole are that needs to be shored up all at once? I just hope it doesn't take a year to finish.
