The "Loop" was a circular trestle that at one point crossed over itself. The trestle was built to avoid the obstacle of building a railroad grade in a very steep section of the mountains. Between 1950 and 1951, the Alaska Railroad management rerouted the line and eventually destroyed the trestle as it was a liability.Caption on photo: The big loop. Mile 47½. A.N.Ry.
