Description
English: From the magazine: Three great types of long-span railroad bridges over the Niagara River, showing engineering progress in the last-half-century: the 800-foot suspension bridge built in 1855; the 550-foot arch replacing it in 1897; the 470-foot cantilever (one of the first ever built) erected in 1883—each of the three about 240 feet above the head of the Whirlpool Rapids.
