The Erlauf bridges involves four new tensioning concrete trough bridge spans 26-30-26 m.<br>The two old structures were limp reinforced concrete in the same shape as the new.
 In the course of the four-pronged expansion of the railway, but had to be removed, because they had not withstood the loads.
 Thus were established two new tension concrete trough structures to replace of the old and through the Viergleisigkeit two additional newly built structures.(Information from Ing.Gerald Steiner)
