Wayne,
It is not shown in any of my photos but the current operating trackage of the Maine Narrow Gauge Museum ends not too far from the water and the trestle.
I would assume there has not been any maintenance or care to the structure since the fire in 1984, yet the wood, especially where it is immersed twice a day in sea water, is in relatively good shape.
Looking at my photos, it appears only the southern approach was on fire, and not the draw span or northern section. Don’t know how yet, but I would like to get a lot closer with a boat to capture some additional images.
