Another and another section islowered. When all are in place the water is pumped out, the connectionsperfected, tracks laid, lights, ventilation, and drainage installed. Your subaqueous bridge is complete and ready for operation—thecheapest and best water crossing ever devised, one not subject to windsand storms like a bridge, nor disturbed by currents or tides, nor painfullybored underground. If the traffic becomes too great for two tracks, anotherdouble-track tube is laid alongside the first, and another and another lateron, as needed.
