Overhead signage for the mandatory truck pulloff on NY 12D north. NY 12D descends on a steep grade as it enters the northern terminus in Lyons Falls. There is supposed to be a large sign at the pulloff describing the downgrade, however the sign was missing at the time this photo was taken.

The large sign at the truck pulloff describing the downhill grade into Lyons Falls. The sign was knocked down during the winter on 2007-08 and has not been replaced since.
