 | | In 1904, Lindenthal, who oversaw the opening of the Williamsburg Bridge and the construction of the ongoing Manhattan Bridge and Queensboro Bridge projects, was chosen as consulting engineer and bridge architect by the Pennsylvania Railroad, which had just acquired the New York Connecting Railroad. |
 | | The 1,017-ft bridge is a two-hinged steel arch with a clear span from center to center of skewback hinges of 977.6 ft. Built to accommodate four railroad tracks, it was designed for a total live and dead load of 76,000 lb per lineal foot. |
 | | The bridge was erected by cantilevering from each pier the arms held in place by tiebacks. |
