South Cable Completed:
On Tuesday, January 24, another noteworthy piece of the new Tacoma Narrows
Bridge was completed. Using 0.196-inch diameter wire, crews finished spinning
the south suspension cable - a total of 8,816 wires. Approximately 9,500
miles of cable was used in spinning the one cable. As the cable was spun,
each wire was precisely placed into one of 19 strands, with each strand
containing 464 wires. The metal frame holding the wires and the large
cable above the strands (at left) are now being removed from the south
cable to prepare for the next phase of work: compacting and banding the
19 strands together to create a 20½-inch diameter main suspension
cable. On the north cable, five of 19 strands are complete.
