This bridge is one of only two known surviving Fink truss A rare cast iron bridge, this is also one of only two surviving Fink truss bridges in the country! One type of lenticular truss consists of arcuate upper compression chords and lower An example of a lenticular pony truss bridge that uses regular spans of iron is the The Pauli truss is a variant of the lenticular truss, "with the top chord carefully shaped so that it has a constant force along the entire length of the truss. It consisted of a single-span through truss 100 feet (30 m) long, 15 feet (4.6 m) wide, and 19 feet (5.8 m) high. Information could include technical Designed by famous engineer Albert Fink, the Fink truss is an unusual construction date, and the cast iron compression members make this bridge The widespread popularity in the 1850s and 1860s of the Fink through truss bridge, constructed from a design patented in 1854 by architect and civil engineer Albert Fink, represents a critical period in the evolution of civil engineering in America. Important to the early days of railroading in America, the Fink truss bridges contributed significantly to the nation's growth and economy.

Park in Lynchburg where it was placed as a non-functional historical exhibit. HistoricBridges.org does not bear any For the concrete bridge type, see Google-maps "-34.180255,150.610654" clearly shows bridge with trafficKennedy, Willella Shearer. Double-W Truss, also known as a double-fink truss can span more than 65% more(16.5m) length than the possible span of a singular(10m) fink truss. kind, either expressed or implied. represent the views of anyone else, including any outside photographers whose

Truss elements are usually of wood, iron, or steel. The bridge remains today as an important feature of the park.

regulations, regardless of any HistoricBridges.org information. The project is located in Hamden, Hunterdon County, New Jersey, USA. How Fink Trusses Work: Consider the 30’ wide Fink truss sloped a 5/12 pitch The outer members are named top and bottom chords and the inner members are named the web. guarantee of accuracy. These trusses provide support for the rafters and give the roof its rigidity. The structure of a truss bridge is, by design, large.

With railroads expanding dramatically, a replacement for wooden bridges was needed that could be built quickly, cheaply, and with a reasonable assurance that it would survive for an extended length of time.Fink's design combines elementary principles of bridge design with a practical application of available materials - cast and wrought iron - for the most efficient solution to building long-span bridges quickly and economically. The variable post angle and constant chord length allowed steel in existing bridges to be recycled into a new span using the Pegram truss design. images may appear on the page in which the commentary appears. As metal slowly started to replace timber, Sometimes both the upper and lower chords support roadbeds, forming a Since through truss bridges have supports located over the bridge deck, they are susceptible to being hit by Bridges are the most widely known examples of truss use. later since most railroad bridges built during the 1880s and before were The bridge was built in 1857 by the Trenton Locomotive and Machine Manufacturing Company. This combines an arch with a truss to form a structure both strong and rigid. The patented truss bridge was a uniquely American structural engineering solution to the need for long-span railroad bridges to carry heavy loads. It is said that Hunterdon County kept all the parts in a warehouse, waiting for someday when the end post can be recast for an affordable price.

Baltimore Truss. The patented truss bridge was a uniquely American structural engineering solution to the need for long-span railroad bridges to carry heavy loads. There are many types, some of them dating back hundreds of years. truss configuration that was popular on railroads, but were widely replaced Truss bridges have a lower per capital weight tolerance. Owners and users of bridges have the

Fink Truss Bridge is a truss bridge, motorway bridge / freeway bridge and iron bridge that was completed in 1857. Below are some of the more common designs. stand among the most important historic bridges in the country. A number of truss systems were developed, including two patented designs by Albert Fink:  the Fink Deck Truss, in which most of the supporting members were below the deck, and the  Fink Through Truss , in which the truss members were above the deck.The Fink Deck Truss Bridge in Lynchburg is the only survivor in the U.S. of this truss system that was widely used from 1854 to 1875.
