Historical Information: From the Americanized Encyclopaedia britannica(1890)...The Brooklyn or East river suspension bridge is one of the engineering triumphs of the age. Starting from a point on Chatham street, opposite the city hall park, New York, it extends to the square bounded by Fulton, Prospect, Sands, and Washington streets, Brooklyn, a total length of 5,989 feet.
The bridge consists of a central span, from shore to shore, of 1,595^ feet; shore spans, from the towers to the cable anchorages, each, 930 feet long; a viaduct approach of masonry on the New York side, 1,562^ feet; and a similar approach on the Brooklyn side, 971 feet. The suspension bridge is supported by two granite towers, over which the cables are passed and secured to heavy anchorage plates, set in solid masonry. The towers rest on caissons, sunk to bedrock below the river, and filled with concrete.
The bridge is eighty-five feet wide, including a roadway on each side for vehicles, a central promenade, thirteen feet wide, for foot passengers, and two railway tracks, on which trains are run at intervals of a few minutes, the traction power being furnished by a stationary engine at the Brooklyn terminus through an endless cable.
The yearly travel amounts to more than 3,000,000 foot passengers; nearly 40,000,000 railway passengers, and an immense number of vehicles. The toll for foot passengers is 1 cent; railway fare, 3 cents; but tickets are sold in packages at the rate of 2 cents by rail; and half of a cent for pedestrians.
The construction of the bridge begun January 2, 1870, and the structure was opened for travel May 24, 1883. The cost of building exceeded $15,000,000. The bridge is the joint property of the cities of New York and Brooklyn.
Weight of entire suspended structure: 6,740 tons
Height of roadway at towers: 119 feet
Height of arches above roadway: 117 feet
Height of towers above roadway: 159 feet;
Cubic yards of masonry in towers: New York, 46,945; Brooklyn, 38,214.
A special policeforce patrols the bridge at all hours for the purpose of preserving order, stopping runaways, etc. The executive personnel consists of six chiefs, thirty-one collectors, seventeen gatemen, ninety conductors, and ninety-one policemen, all under control of the board of trustees.
