Tioronda Bridge

The Tioronda Bridge once carried South Avenue in Beacon, New York, across Fishkill Creek. Built between 1869 and 1873 by the Ohio Bridge Company, it was demolished by the city in December 2006. [2] The bridge had been listed on the National Register of Historic Places in 1976, but a decade later had deteriorated to the point that it had to be closed. [3]


Three stone abutments laid in randomly coursed ashlar remain in the river, with one steel stringer and some utility pipes. They supported three spans 34 feet (10 m) in length for a total span of 110 feet (34 m). The bowstrings, arched hollow tubes which once carried the load but later only became guardrails, were the bridge's distinctive structural feature. [1]

It was one of the last remaining bowstring truss bridges in the United States, one of the oldest vehicular bridges in New York and one of the few 19th century iron bridges known to have been based on a patent model. Only one other bridge, over Sandy Creek in Allegheny County, Pennsylvania, is known to have been built from that model as the Ohio Bridge Company ceased operations in 1873, possibly due to that year's economic crisis. [1]

The trusses themselves were preserved for possible ornamental use on a rebuilt bridge. [2] However, it is not known when such rebuilding would take place, and the city's police and fire departments would like a rebuilt bridge to be wider than the current abutments and decking, still in place, would allow for.

The Coraopolis Bridge is a girder bridge over the back channel of the Ohio River connecting Grand Avenue on Neville Island to Ferree Street in Coraopolis, Pennsylvania. It opened in 1995 to replace a structure of historic significance. The original Pratt/Bowstring/Pennsylvania through truss spans, designed by Theodore Cooper, were formerly the (third) Sixth Street Bridge, spanning the Allegheny River, in downtown Pittsburgh, and were built in 1892 by the Union Bridge Company. They were floated downstream by the Foundation Company in 1927 rather than being demolished when the bridge was removed to enable construction of the present (fourth) Three Sisters (Pittsburgh) Sixth Street Self-anchored suspension bridge. However, by the late 1980s, the old bridge could no longer support traffic volumes and was replaced by a newer structure.

<span class="mw-page-title-main">Laughery Creek Bridge</span> Bridge in Indiana and Ohio County, Indiana

The Laughery Creek Bridge is a triple whipple truss bridge on the border of Dearborn County, Indiana, and Ohio County, Indiana. It crosses Laughery Creek. This bridge was built in 1878. The Wrought Iron Bridge Company, a prolific late 19th-century bridge company, constructed the bridge. The bridge is seated on stone abutments. The deck surface is not original and is currently concrete. The bridge, nearly 300 feet in length, is a single span pin connected triple intersection Whipple through truss, and is the only example in the world of this truss type. The name bridge's nickname, "Triple Whipple Bridge" is a play on words. The double-intersection Pratt, which was called the Whipple truss configuration, was a far more common variation of the standard Pratt configuration. Since the Laughery Creek Bridge's members have three intersections instead of two, this gives rise to the "Triple Whipple" name. This bridge was listed on the National Register of Historic Places in 1976.

The Bollman Truss Railroad Bridge across the Little Patuxent River at Savage, Maryland, is one of the oldest standing iron railroad bridges in the United States and the sole surviving example of a revolutionary design in the history of American bridge engineering. The 160-foot (48.8 m) double-span was built in 1852 at an unknown location on the main line of the Baltimore and Ohio Railroad. It was moved 35 years later to its present location, where it replaced the very first Bollman bridge. Today, it carries the Savage Mill Trail.

<span class="mw-page-title-main">Shinn Covered Bridge</span> United States historic place

The Shinn Covered Bridge is a historic wooden covered bridge in the southeastern part of the U.S. state of Ohio. Located in the countryside northeast of Bartlett in Washington County, this single-span truss bridge was built in 1886 by local carpenter Charles T. Shinn. Built of weatherboarded walls with stone abutments and a metal roof, the bridge features vertical siding, and its portals have remained vertical and resisted creeping into another shape. The heart of the bridge's structure employs the Burr Truss design, which mixes the king post truss with a wooden arch designed by Andrea Palladio in the sixteenth century. Shinn built his bridge to span the western branch of Wolf Creek in Palmer Township. Measuring 98 feet (30 m) in length, the bridge was constructed soon after the drowning of one of Shinn's children.
