This bridge is noteworthy for its use of bolted connections. While not the earliest example of the use of bolted connections, it is still part of a period of time in history where bolted connections were occasionally used as builders transitioned from pins to rivets in connections. Bolted connections would later make a comeback in the second half of the 20th Century.

Statement of Significance
Bolted Warren ponies represent a fairly short, intermediate stage in the truss' development towards all-riveted structures. This bridge is of standard design for its type and stage and retains its original members, including latticed guardrails.
Concrete abutments and wingwalls support the single-span, somewhat skewed Warren pony truss. The largely-bolted structure extends 64' in four panels. Its all-interior verticals and its diagonals are manufactured from a pair of angles riveted together with battens. The I floor beams are bolted to gussets and the verticals below the lower chord and carry the asphalt-over-concrete deck with its 16' roadway.
This bridge was built over McHargue Ditch, near the Weddle property in Brownstown Township, by a local contractor, Henry Harman, for the sum of $1044.00. The contract letting date was 11 March 1918. [county research results]
