Despite this, the Carroll Street Bridge is actually a New York City historic landmark. It is one of only three remaining retractable bridges operating in the United States! It is also the only wooden bridge in NYC used for cars! (More bridge fun facts: one of the other two retractable bridges also resides in NYC, the Borden Avenue Bridge in Hunters Point, Queens).

By the 1860s, the Gowanus Canal was becoming a central hub of modern-day industrial activity for the city of Brooklyn. To advance this industrialization, the city built six bridges to cross the canal. One of them was the original and non-retractable Carroll Street Bridge, an old wooden swing bridge, which closed in 1887 due to fears of its imminent collapse.

In 1888, Brooklyn Mayor Alfred Chapin and the Brooklyn Common Council announced their plans for a replacement bridge. One request by local landowners for the new design was a retractable span that could slide into the shore to allow an easier passage for boats (the canal was narrower at Carroll Street). The city approved this design and construction began that same year.

The new Carroll Street Bridge opened in 1889 at the cost of $29,600 to build and was designed by the Department of City Works engineers Robert Van Buren and George Ingram. Since then, there have been only slight alterations to the structure. One necessary modification came in 1908 when the bridge’s steam motors were replaced by electric motors.

Despite being closed twice in the 1970s, as well as an incident in the mid-1980s that resulted in the bridge being stuck in the open position for several years, the Carroll Street Bridge is a resilient little piece of architecture. In 1987, the New York City Landmarks Preservation Commission designated the bridge an official city landmark.
