Factory Bridge
Also known as: Horsham Bridge

Why it's listed
Built in 1880, the Factory Bridge is a single-span covered bridge of 60 feet that crosses White Deer Creek in White Deer Township, about a mile from the village of West Deer in Union County. It has a combination of multiple King and Queen trusses and a roadbed 16 feet wide. The bridge takes its name from a woolens mill that once stood nearby and drew its water power from the creek. That mill burned about a century before the nomination was prepared, but a cluster of houses remains a short distance away on the old White Deer Turnpike. The bridge was repaired in 1954 and again in 1976, and it is in good condition after recent painting. Its significance rests on its engineering, its trusswork, and its connection to the local industrial history of White Deer Creek. It is also the only surviving covered bridge on that stream.
Significance in brief: The nomination ties the bridge to a former woolens mill nearby that took its power from the creek and gave the bridge its name. It is described as the only remaining covered bridge on White Deer Creek. The form also cites its multiple King and Queen truss construction as a notable engineering type.

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.
