Henniger Farm Covered Bridge
Also known as: Dauphin County Bridge #43 (38-22-11)
Why it's listed
Spanning Wisconisco Creek in the northeast corner of Washington Township, Dauphin County, this single-span frame covered bridge measures 72 feet including its stone and concrete abutments. Its trussing combines Burr and double arch systems, and it carries a 16-foot plank deck with 11 feet of clearance. Six window openings under the projecting eaves admit light and air, and vertical planking painted white covers the exterior. Early advertisements remain painted on the interior beams and walls. The creek once powered grist mills, sawmills and factories, with ten to twelve operating on the Wisconisco by 1840. Floods in 1972 destroyed most of the county's remaining covered bridges, leaving this structure as the only in-situ covered bridge wholly within Dauphin County. Its construction date and builder are unrecorded.
Significance in brief: The nomination argues the bridge is significant as the only remaining in-situ covered bridge wholly in Dauphin County, after the 1972 Agnes Flood destroyed most of the county's remaining covered bridges. It also points to the creek's role as a source of power during the 1800s, when the Wisconisco supported numerous mills and factories.

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.
