This bridge is an extremely early example of a truss bridge with bolted connections. Bolted connections only became popular in the second half of the 20th Century, as riveting lost favor as the preferred bridge fastener type. This bridge retains good historic integrity. It has been supplemented with post-tensioning cables, but these do not diminish the original material or design. The bridge is a short through truss at around 90 feet, and has 14.3 Feet of vertical clearance.
Information and Findings From DHPA Historic Bridge Survey
Statement of Significance
Bolted Pratt through structures are not common in Indiana. The varied size of the diagonals is also noteworthy. The bridge retains its original members, including latticed portals.
Seated upon concrete abutments and wingwalls, this largely-bolted Pratt through span extends 92' in six panels. A pair of channels riveted together with battens provides each set of intermediate verticals, and a pair of angles and battens supply the diagonals and counters. The angles of the outer diagonals are heavier than the inner ones. Only the two most central panels are countered. The I floor beams are bolted to gussets below the lower chord. The bridge carries a timber deck with a 15'8" roadway and 15' of vertical clearance.
