Brooklyn Bridge trolleys

From 1898 to 1950, various companies operated local trolley lines over the Brooklyn Bridge, taking passengers from many points in Brooklyn and Queens, New York City, United States to the Park Row terminal in Lower Manhattan.

This line was chosen because of its half-hour headway, and its cars began crossing the bridge on January 23, 1898.

[2][3] A new elevated trolley line on the Brooklyn end of the bridge opened on September 28, 1908, taking trolleys bound for Fulton Street through the Sands Street station of the elevated railways and underneath the connection to the Fulton Street Elevated.

The cable cars of the New York and Brooklyn Bridge Railway, on whose tracks the Brooklyn Rapid Transit Company was providing through elevated railway service, were discontinued the next day.

[5] Local trolley service ended on March 6, 1950 to permit the reconstruction of the bridge's roadway.
