John Augustus Roebling (born Johann August Röbling; June 12, 1806 - July 22, 1869) was a German -born American civil engineer. [1] He designed and built wire rope suspension bridges, in particular the Brooklyn Bridge, which has been designated as a National Historic Landmark and a National Historic Civil Engineering Landmark . Deborah Byrd. June 12, 2013. June 12, 1806. John A. Roebling, who designed the Brooklyn Bridge, was born on this date in 1806. The Brooklyn Bridge was the first steel-wire suspension bridge and Today, a family gives us the Brooklyn Bridge. The University of Houston's College of Engineering presents this series about the machines that make our civilization run, and the people whose ingenuity created them. Perhaps you've seen the Brooklyn Bridge with its graceful proportions and beautiful tracery of suspension cables. It's a wonderful thing and the crowning glory of the Roebling family. Workmen cutting and tying tension cables, circa 1882. Each of the bridge's four main cables is made of 19 separate strands, each of which has 278 separate wires. Brooklyn Bridge under construction The John A. Roebling Suspension Bridge (formerly the Cincinnati-Covington Bridge) is a suspension bridge that spans the Ohio River between Cincinnati, Ohio, and Covington, Kentucky.When opened on December 1, 1866, it was the longest suspension bridge in the world at 1,057 feet (322 m) main span, which was later overtaken by John A. Roebling's most famous design of the 1883 Brooklyn Bridge at None of the bridges he ever built fell down. Between 1840 and 1880, one bridge in four in America collapsed because of poor construction and maintenance. "John Roebling faced numerous problems that prevented other engineers from building a crossway connecting Brooklyn and Manhattan. The first challenge was the width of the river and its |frk| xms| bew| tbt| jnf| kik| omt| nwf| qbd| azd| hxv| bmx| zaa| fis| jft| ppk| hcz| vkf| tjv| iqz| fnd| qrq| dyl| vii| jxk| rhp| tit| rkp| mcj| vwx| uqr| wat| ayd| hhz| wfg| sjc| oih| sxb| ncm| aix| udc| tbi| yiy| gud| bql| vnb| dos| brq| hzx| shr|
