Summary
[edit]
| Description | Essex-Merrimac Bridge, spanning the Merrimack River between Newburyport & Deer Island, Amesbury, Essex County, Massachusetts, USA. The Essex-Merrimac Bridge is a 225-foot, single-span suspension bridge, which crosses the Merrimac River at the site of a previous Palladian, arched timber truss (1792-1810) built by Timothy Palmer, and a wrought-iron chain suspension bridge (1810-1909) designed by James Finley and built by John Templeman. The fame of the current bridge rests largely on the accomplishments of these earlier bridge builders, rather than its own engineering merits. Even so, at its time of construction in 1909, the Essex-Merrimac Bridge incorporated the most up-to-date technology. George F. Swain, the bridge's designer, was a nationally-recognized structural engineer and educator. According to the Massachusetts Department of Public Works Historic Bridge Inventory, the Essex-Merrimac Bridge is Massachusetts' only highway suspension bridge.
