MOVING A BRIDGE.
AX ENGINEERING FEAT. An interesting experiment has .just been made in Vienna. The old “ Brigif fabruckc ” across the Danube canal is to be replaced by a large modern construction for heavy traffic. As the new bridge will occupy the present site of the old bridge, the latter had to be moved a wav a little.
The bridge was loosened from the street at both ends, lifted and placed on cars which ran on heavy iron rails. Within an. hour and a half seven hundred tons were drawn up-stream for a distance of twenty metres. Comparatively little human strength was necessary to turn the four cranes, and the bridge moved forward across wire ropes stretched tightly. The movement was so slow that one could not notice it, but in the centre of the bridge a large clock showed from one second to the next the movements to the right and left. All depended on both sides advancing equally and the directions were given by telephone from the conning bridge.
Notwithstanding the severe cold, a large crowd gathered and followed the enterprise- with feverish excitement.
