“ A curious chain suspension bridge across the Merrimac, connecting Newburyport with Amesbury, was built in 1827, replacing a similar bridge built in 1810, which was one of the first suspension bridges in America. Newburyport in the early part of the 18th century was one of the most prosperous commercial centres in New England. At that time fishing, whaling and shipbuilding were its principal industries, the clipper ships built here being among the fastest and best known on the seas. After the Civil War manufacturing became Newburyport’s chief interest. ”
