Hardesty & Hanover LLP of New York City, is 90 feet (27 m) wide and 270 feet (82 m) long with two 30-foot (9.1 m) tower spans and six 100-foot (30 m)-long approach spans. The lift span weighs almost 6,500,000 pounds (2,900,000 kg) with a total load-to-move of 13,000,000 pounds (5,900,000 kg). It provides a channel with 240 feet (73 m) horizontal clearance and 13 feet (4.0 m) vertical clearance when the span is closed, and an additional 62 feet (19 m) vertical clearance when it is open.

When closed, clearance under the bridge was 12 feet (3.7 m) at mean high water, ranging from 8–17 feet (2.4–5.2 m) at extreme high tide to extreme low tide. The channel width was 117 feet (36 m), with a total span length between centers of 148 feet (45 m). The builder was the

The first bridge here was erected in 1797 by Isaac
Tomlinson's group to replace profits from their ferry ruined by a new bridge. This 27-foot (8.2 m)-wide covered wooden truss bridge included a draw to allow vessels through. It has also been described as a "wood and sandstone" bridge.

The second bridge, 1885-1922, was an iron bridge which was never particularly good, having been salvaged from a scrap yard, and not thought well of even before then. By 1913, this bridge was opening 17,000 times a year. Plans for replacement were created during
