  • Description
  • The Sixth Street Bridge was the second bridge of four that was built across the Allegheny River at Sixth Street in downtown Pittsburgh. The multi-span suspension bridge was built in 1859 by John A. Roebling, creator of the Brooklyn Bridge in New York City, and the second bridge at Smithfield Street in Pittsburgh. The bridge had two main spans of 344 feet each and the main cables at each side of the roadway were 22 feet apart center to center. The main cables were 7 1/2 inches in diameter and composed of seven strands of 700 wires each, and weighed 115 pounds per foot. In 1892 Theodore Cooper prepared plans for a third bridge at the site capable of accommodating the rapidly increasing travel and electric cars to cross without reducing their speed.
