Santa Fe bridged gap with three 60-ft deck girder spans and 22-ft beam span, when derailment caused collapse of truss span across Washita river; recommendation was to construct three new piers of 14 in. 117-lb steel H-piles inserted and grouted in holes drilled 6 ft into rock; to cope with fast water and rock bottom, method was to fabricate templates of 30 in. pipes, sink them to rock, drill holes into rock through pipes, and insert H-piles.
