Bridge Documentation

View Archived National Bridge Inventory Report - Has Additional Details and Evaluation

This bridge was built ca. 1930. It follows a state standard plan for truss bridges. In 1957, it was moved and reused here in its current location. The relocation of truss bridges has historically not been uncommon since the structure type is easy to relocate. Bridges that became insufficient for busy roads could be moved and used on quieter rural roads. Even today, truss bridges continue to be moved, but more often for historic preservation reasons.

Statement of Significance

The design of this structure is quite conventional for the period. It follows IDH patterns established in the 1920s, except that some truss members are a bit heavier than was typical in the previous decade. Variations between panels in the diagonals and lower chord members reflect additional stiffening. The bridge retains its original latticed guardrails.

Architectural Description

The Indiana Department of Highways continued to design riveted Warren pony trusses throughout the 1930s for some spans requiring less than 100'. Brown County had each truss of this structure cut into three sections and moved from a state highway to its current location where the trusses and floor beams were bolted into place.

The bridge consists of a single, half-hip span of 84' in seven panels erected upon replacement concrete abutments and wingwalls. Its diagonals are made from a pair of angles which are heavier at the endposts than towards center span. The lower-chord members are also varied in size, the outer-panel ones being fabricated from a pair of angles and battens and the inner ones each using two pairs of angles. The verticals consist of two pairs of angles riveted together with batten plates shared with the external braces. The battens integrate the sway bracing with the vertical members. The I floor beams are bolted to gussets and the verticals above the lower chord and carry a fairly new concrete deck with its 22' roadway.

ALTERATIONS: New concrete deck, replacement concrete abutments & wingwalls, additional stiffening to diagonals & lower chord members.
