County Bridge No. 124
Also known as: Co. Br. 124

Why it's listed
Beaver Creek carries this three-span stone arch bridge on Edge Hill Road in Caln Township, Chester County, Pennsylvania. The structure measures 72 feet overall, with three spans of 24 feet each, and was built in 1916 by Dunleavy Bros., as recorded on a plaque set into the parapet wall. It is built of squared ashlar in the manner of nineteenth-century Pennsylvania stone bridges, and its design is considered high in quality. Features include small conical piers and a continuous parapet topped with contrasting sandstone coping. The survey form records the bridge as unaltered and in good condition. It is regarded as a very well-preserved, typical example of the intermediate-length multi-span stone bridge found in Chester County. Its recognition is part of a group of Commonwealth-owned highway bridges, and engineering was added as an area of significance.

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.
