The Williamsburg Bridge ca. 1905 The Williamsburg Bridge opened to the public on December 19, 1903, spanning the East River and connecting Manhattan’s Lower East Side with the Brooklyn neighborhood of Williamsburg. It was designed by American Civil Engineer Leffert L. Buck and architect Henry Hornbostel who would later also collaborate on the design of the nearby Queensboro Bridge. This time period coincided with a massive population growth in New York City, prompting an ease of movement between boroughs and necessitating the need for more connections. The Williamsburg Bridge was the second permanent structure to connect Lower Manhattan and Brooklyn following the opening of the Brooklyn Bridge in 1883. Construction began in 1896 and cost the city $24.2 million in total. At the time of it’s opening, the Williamsburg Bridge was officially the longest running suspension bridge in the world, spanning a total of 7,308 feet. The structure would hold this title until 1924, when the Bear Mountain Bridge opened in upstate New York. The Williamsburg Bridge was one of the last bridges built in New York City designed for the purpose of trolley use. In the decades after it opened, railways and trolley lines accounted for most of the traffic on the bridge. To accommodate the growing frequency of automobile drivers, the trolley tracks were closed and converted into roadways in 1932.

Williamsburg was incorporated into Bushwick as the "Village of Williamsburgh" within the Town of Bushwick in 1827. After two years, it had a population of over 1,000, a fire department, and a post office. Its prime location on the East River encouraged industrialists to build shipyards around Williamsburg. As such, it became a hub of industry. In 1840, Williamsburg separated from the Town of Bushwick and became the Town of Williamsburg. Edmund Smith Driggs, a Williamsburg resident, was elected the first president of the Village in 1850. Driggs Avenue is named after him. It became the City of Williamsburg (then discarding the 'h' in 1855 and was organized into three wards. Finally, in 1898 Brooklyn became one of the high boroughs within NYC and so Williamsburg became part of the City of Greater New York. The Williamsburg Bridge was opened shortly after.

Williamsburg Bridge from South 6th and Berry Streets, April 28, 1937. Whereas the Brooklyn Bridge served to unite two independent cities, the Williamsburg Bridge (also spelled "Williamsburgh"), completed after the consolidation of Greater New York, functioned as a highway within the single, larger city. The Williamsburg, the first all-steel suspension bridge, had been proposed as early as 1882, even before the completion of the Brooklyn Bridge, but its realization was long opposed by powerful ferry interests. Residents of Brooklyn's Williamsburg section felt that the area was suffering economically and in status after the Brooklyn Bridge opened and focused attention on Manhattan and away from their neighborhood. In addition, construction of the Brooklyn Bridge had escalated the population and property values in the city of Brooklyn; simultaneously the growth rate of the village of Williamsburg (also known as the Eastern District) declined. After the Williamsburg Bridge opened, the few orthodox Jews who had earlier settled in Williamsburg, one of the many small towns that comprised Brooklyn, were soon joined by many other Jewish immigrants who fled the squalor of Manhattan's overcrowded Lower East Side tenements. Although not considered as aesthetically satisfying as the Brooklyn Bridge, the Williamsburg enjoyed its own renown. It was the first suspension bridge to feature towers made entirely of steel, and the 110-foot depths to which its caissons were sunk represented a new engineering accomplishment. When finally completed, the Williamsburg was the longest suspension bridge in the world, 4.5 feet longer than the Brooklyn Bridge. For five years after the Williamsburg opened, the City was unable to coordinate mass transportation activities for it; only walkers, cyclists, and privately-owned carriages used the span. In 1908, the Brooklyn Union Elevated Railroad Company (later the Brooklyn Rapid Transit Co., now the BMT) became the first mass transportation line to cross the bridge.
