Map 

Description 

The Apache Canyon Bridge crosses the canyon diagonally. The girders are 105 ft. in length. The track, intersecting three loops of the Galisteo River at Apache Canyon, makes six crossings over a space of more than two thousand feet. An extremely oblique skew span (105 ft. long) is capable of center support by a transverse secondary span at the center arranged to transform the primary span into two continuous plate girder deck spans. The ends of the bridge rest on abutments on opposite sides of the canyon. The center line of the track is on a ten degree curve and is 14% inches off the center line of the plate girder bridge at the center and at both ends of the span. The abutments are anchored in granite rock on both sides of the canyon. The trackbed on the structure measures ten feet in width and the distance between the center point of the structure and the shorter pedestal supporting the deck girder is sixteen feet.
