Plans to build a rapid transit system in New York were first made in 1831. By 1868 the first elevated railway was erected. As the "El" became crowded, construction of an underground railway was proposed. Ground was broken on March 24, 1900. The original subway, which took opened October 27, 1904, ran 9.1 miles from City Hall to 145th Street and Broadway. The fare was a nickel. Extensions to the Bronx opened in 1905 and to Brooklyn in 1908, completing the first subway.

The 1.6-mile Holland Tunnel was the first underwater vehicular crossing of the Hudson River and the first tunnel specifically designed for automobiles and trucks. It dramatically reduced the time required to traverse the Hudson River, a trip previously possible only by ferry.
A major difficulty when tunneling beneath a river is to keep water and mud from inundating the workers and equipment in the tunnel. Builders of the Holland Tunnel used a shield that enveloped the work site as the excavation progressed; this also avoided obstruction of shipping traffic during construction.
