THIRD LEG TO TOWERS DOUBLES BRIDGE WIDTH

The article describes how engineers added a third leg to each tower, strung a new suspsension cable, and lightened the old and new road decks so that an original cable on a suspension bridge centerline can support both roadways in Cologne, Germany. By removing the deck concrete, the 40-year-old structure will be strong enough to support half a new steel deck, requiring only one extra cable to be added. For environmental reasons, a new alignment could not be built, and the alternative designs were more expensive. Details of the construction are summarized.
