The Northern Boulevard crossing, also called the "Flushing Bridge", is located north of the Roosevelt Avenue bridge and the former Whitestone Branch trestle. Several bridges have existed at the site, the first of which was built  1800–1801, making it the oldest crossing of the Flushing River.
Five additional drawbridges were built at this location. A replacement drawbridge was erected in the mid-19th century, followed by swing bridges in 1866 and 1890, an elaborate bascule bridge in 1906, and a simpler bascule bridge in 1939.
