The Susitna River Bridge is a railroad bridge of the Alaska Railroad in south-central Alaska. It spans the Susitna River on the eastern edge of Denali State Park near Gold Creek. The bridge is on the National Register of Historic Places.
Construction of the bridge took place from October 1920 to February 1921. The span is 503 ft., with a height of 71 ft. in the center; the steel weighs 2,000 tons, and rests on two concrete piers, each 50 ft. high and 70 x 40 ft. in cross-section, and each containing 1,500 cubic yards of concrete. The location was chosen, just downstream of a curve, after observing the pattern of ice jams through the preceding three years.

Famous quotes containing the word bridges:
“We live technologically, with man as the master of nature, man as the engineer, and let anyone who raises his voice against it stop using bridges not built by nature.... No electric light bulbs, no engines, no atomic energy, no calculating machines, no anaesthetics—back to the jungle.”
—Max Frisch (1911–1991)
“If the Revolution has the right to destroy bridges and art monuments whenever necessary, it will stop still less from laying its hand on any tendency in art which, no matter how great its achievement in form, threatens to disintegrate the revolutionary environment or to arouse the internal forces of the Revolution, that is, the proletariat, the peasantry and the intelligentsia, to a hostile opposition to one another. Our standard is, clearly, political, imperative and intolerant.”
—Leon Trotsky (1879–1940)
“to-morrow it seem
Like the empty words of a dream
Remembered on waking.”
—Robert Bridges (1844–1930)
