Fink truss

Albert Fink designed his truss bridges for several American railroads especially the Baltimore and Ohio and the Louisville and Nashville.

[3] It is identified by the presence of multiple diagonal members projecting down from the top of the end posts at a variety of angles.

This gives the bridge an unfinished saw-toothed appearance when viewed from the side or below, and makes the design very easy to identify.

The Zoarville Station Bridge consists of one of the original three spans of a through truss of Fink design built in 1868 by Smith, Latrobe and Company of Baltimore, Maryland.

[8] Fink design trusses are used today for pedestrian bridges and as roof trusses in building construction in an inverted (upside down) form where the lower chord is present and a central upward projecting vertical member and attached diagonals provide the bases for roofing.
