The Knowlesville Lift Bridge is located on Knowlesville Road in Ridgeway, New York, and is a part of the New York State Canal System (formerly known as the New York State Barge Canal). [1] The vertical-lift bridge is a Warren truss with a length of 145 feet (44 m) sitting on concrete abutments, and has an open grate deck. [1] The east side of the bridge has a truss erected in 1964 used to carry a gas pipeline across the Erie Canal. [1] It has a normal water surface elevation of 514 feet (157 m), and a normal overhead clearance of 16.57 feet (5.05 m). [2] According to the New York State Department of Transportation, 1,100 vehicles use the bridge daily. [3]
The contract for building the bridge was awarded to the Thomas Crimmins Contracting Company of New York, and machinery operating the bridge was installed in 1910. [1] [4] The bridge was rehabilitated, and a new control building was built, in 1975. In 1985, the bridge's electrical systems were rehabilitated. [1] The bridge was closed for steel repairs in November 2017 and reopened the following year in June 2018. [5] [6]

A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently.
The Broadway Bridge is a vertical-lift bridge across the Harlem River Ship Canal in the borough of Manhattan in New York City. It connects the neighborhoods of Inwood on Manhattan Island and Marble Hill on the mainland. The bridge consists of two decks. The lower deck carries Broadway, which is designated as U.S. Route 9 at this location. The upper deck carries the New York City Subway's IRT Broadway–Seventh Avenue Line, serving the 1 train.

The Arthur Kill Vertical Lift Railroad Bridge is a rail vertical-lift bridge connecting Elizabethport, New Jersey and the Howland Hook Marine Terminal on Staten Island, New York, United States. The bridge was built by the Baltimore and Ohio Railroad in 1959 to replace the Arthur Kill Bridge, a swing bridge opened in 1890. It contains a single track that is used mainly to carry garbage out of New York City, as well as to transport freight to destinations in western Staten Island. The bridge parallels the Goethals Bridge, which carries Interstate 278. It has the longest lift span of any vertical-lift bridge in the world, with two 215-foot (66 m) towers and a 558-foot (170 m) truss span that allows a 500-foot (152 m) channel. It clears mean high water by 31 feet (9.45 m) when closed and 135 feet (41 m) when lifted.
The Hares Hill Road Bridge is a single-span, wrought iron, bowstring-shaped lattice girder bridge. It was built in 1869 by Moseley Iron Bridge and Roof Company and is the only known surviving example of this kind. The bridge spans French Creek, a Pennsylvania Scenic River.
Shaw Bridge, also known as Double-Span Whipple Bowstring Truss Bridge, is a historic bridge in Claverack, New York, United States. It carried Van Wyck Lane over Claverack Creek, but is now closed to all traffic, even pedestrians. It is "a structure of outstanding importance to the history of American engineering and transportation technology." Specifically designed by John D. Hutchinson, the bridge employs the basic design of Squire Whipple. It is the only extant double-span Whipple bowstring truss bridge in the U.S.
The Whipple Cast and Wrought Iron Bowstring Truss Bridge, is located near the entrance to Stevens Farm in southwestern Albany, New York, United States. It was built in 1867, but not moved to its present location until 1899. It is one of the oldest surviving iron bridges in the county, one of the few that use both cast and wrought iron and one of only two surviving examples of the Whipple bowstring truss type. In 1971 it was listed on the National Register of Historic Places, the only bridge in the city of Albany so far to be listed individually.
The Fairport Lift Bridge is a through-truss mechanical vertical-lift bridge that carries NY Route 250 over the Erie Canal in downtown Fairport, New York, United States. It was constructed in 1913–14 by the Lackawanna Bridge Company of Buffalo, New York, and contracted by H. S. Kerbaugh, Inc. of Philadelphia, Pennsylvania, replacing an 80-foot (24 m) fixed bridge built in 1886, which was removed when the Erie Canal was widened. The Fairport Lift Bridge officially opened to automobile traffic on August 15, 1914. Originally having a wooden deck made of yellow pine, the bridge floor was replaced with steel grating in later years. It is one of sixteen vertical lift bridges located along the western portion of the Erie Canal between Fairport and Lockport.
The New Hampton Pony Pratt Truss Bridge is a historic pony Pratt truss bridge on Shoddy Mill Road in New Hampton of Lebanon Township, Hunterdon County, New Jersey.

Lowthorp and built in 1868 by William Cowin of Lambertville, New Jersey. The bridge was added to the National Register of Historic Places on July 26, 1977 for its significance in engineering, industry and transportation. It is one of the few early examples of iron Pratt truss bridges remaining in the United States. It was later documented by the Historic American Engineering Record in 1991. It was added as a contributing property to the New Hampton Historic District on April 6, 1998.
