Five years in the making


German-born John A. Roebling and his son, Washington A. Roebling, designed and built the Brooklyn Bridge connecting New York and Brooklyn. The remarkable design used Roebling's patented system of steel wire cable construction. When it was completed in 1883, the 1,595-foot main span was the longest suspension bridge in the world. Its graceful limestone and granite towers, pictured here, took 5 years to build.
