'James Finley' (
1756 -
1828), also known as 'Judge James Finley', is widely recognised as the the first designer and builder of the modern
suspension bridge.
His
Jacob's Creek Bridge, built in
1801 and demolished in
1833, was an early example of a suspension bridge using
wrought iron chains. It connected
Uniontown to
Greensburg,
Pennsylvania, USA, spanning 21 metres (70 feet).
Other bridges by Finley or to his patent include:
★
Potomac River,
1807, 39 metre span
★
Schuylkill Falls,
Philadelphia,
1809, two 47 metre spans, collapsed 1811 under a herd of cattle
★
Newburyport, Massachusetts over the
Merrimack River,
1810, 74 metre (244 feet) span, collapsed
1827
★
Brownsville, Pennsylvania, collapsed in
1820 under a snow-covered cart
★
Lehigh River,
Northampton, Pennsylvania, retained in service until
1933
None of Finley's bridges now survive.
Finley patented his system in
1808 and also published a paper on the principles of the deck-stiffened suspension bridge.
