Ihe Spanish Cala Iron Company recently built a private rail-road about 60 miles long from its mines in the interior to the portor Seville, where it ships ore by vessel. Its original plan foi- ter-minal docks in Seville included two timber loading wharves alongthe river, approached by timber trestles and earth embankmentsover the low ground between the river bank and the high groundfurther inland. Work had already been begun on this plan andsome of the approach embankment made when the company de-cided to build the loading wharves of reinforced concrete insteadof timber and instead of timber trestle and embankment approachesto use reinforced concrete viaducts. The change in plan was de-cided on because of the height of the approach viaducts necessary.

The two wharves are about 600 ft. apart. The completed partot the embankment was made use of in building the approachviaduct to one of the docks. Nine spans of concrete viaduct werebuilt between the end of the embankment and the wharf. The otherviaduct approaching the second wharf is built entirely of reinforcedconcrete girder spans. In general the concrete spans of both viaducts are is double-tracked and is built in two levels. The upper level high water. Additional lateral bracing is provided for the high col-umns at about 42 ft. 7 in. above high water. Each lateral row offour columns supporting the two tracks res
