Bridge in East Fallowfield Township

Why it's listed
Over a dry mill race in the village of Mortonville, East Fallowfield Township, Chester County, Pennsylvania, stands a small single-span arch bridge carrying Strasburg Road. It spans about 12 feet 6 inches and is built of rubble masonry, with a semi-circular arch and masonry wing walls. The bridge lies beside the Brandywine Bridge and near an extant stone mill, and it remains in vehicular use. Its construction date is not known, though it may have been built during the Brandywine Bridge project. Its significance rests on engineering. The bridge is regarded as a very well preserved example of the many small, single-span rubble masonry bridges built across Chester County. Patch repointing is the principal alteration recorded. The nominated property covers a rectangle of about 30 by 25 feet bounded by the outside corners of the wing walls, and it includes only the superstructure and substructure of the bridge. It was listed in 1988 as part of a group of Pennsylvania Department of Transportation highway bridges.
Significance in brief: The nomination describes the bridge as a very well preserved representative of the numerous small, single-span rubble masonry bridges built in Chester County. It stands adjacent to the Brandywine Bridge and near an extant stone mill, and it is nominated under engineering 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.
