Stone Quarry Bridge
Also known as: Bridge Number3111

Why it's listed
Quarry Bridge carries a township road over the Embarras River northeast of Charleston, Illinois, close to the Charleston Stone Company quarry that gave it its name. Built in 1883 by the King Iron Bridge Company of Cleveland, Ohio, at a cost to Coles County of $4000, it is the oldest bridge in the county. The single span is a double intersection Pratt pinned through-truss of steel and iron with a timber deck. Its main truss measures 180 feet in 12 panels, with a roadway 16 feet wide. The bridge lies on the old Paris to Pana trail and linked the eastern third of the county with Charleston, the county seat. Its engineering interest lies in the truss type, developed by Squire Whipple in 1846 and marked by long diagonals crossing two panels. The design was widely used between 1865 and 1885, and this is the only example in Coles County. Rust is considerable, and the bridge was rated fair in a recent state inspection.
Significance in brief: It is the oldest bridge in Coles County and the only double intersection Pratt truss in the county. It served as a connector between the eastern third of the county and the county seat at Charleston. It was built near the end of the period when this Whipple-type truss was popular, roughly 1865-1885.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
