James Finley (engineer) dating history

Details

James Finley (1756 – 1828), aka Judge James Finley, is widely recognized as the first designer and builder of the modern suspension bridge. Born in Ireland, Finley moved to a 287-acre (1.16 km) farm in Fayette County, Pennsylvania, near Uniontown. Elected a justice of the peace in 1784, he went on to become county commissioner in 1789, and a member of the Pennsylvania House of Representatives and Senate. From 1791 until his death, he was an Associate Judge for Fayette County.
His Jacob's Creek Bridge, built in 1801 for US$600, and demolished in 1833, was the first example of a suspension bridge using wrought iron chains and with a level deck. It connected Uniontown to Greensburg, spanning 70 feet (21 metres), and was 12 feet 6 inches (3.81 m) wide.
Finley is also credited with designing and constructing a chain suspension bridge across Dunlap's Creek in Brownsville, Pennsylvania, in 1809. In 1820, however, the bridge collapsed under a heavy snow combined with the loads from a six-horse wagon team. The bridge was replaced by the Dunlap's Creek Bridge, the country's first cast-iron bridge, in 1835.
