Henninger Farm Covered Bridge is the last covered bridge in Dauphin County standing in its original location. Constructed about 1880, it was reconstructed in 2003 after a fire. The bridge has a Burr arch truss as its structural support system. Like all covered bridges, it is roofed and sided to protect the decking and trusses from weather. In the early 1970's, Henninger was one of six covered bridges on Wiconisco Creek and one of nine in Dauphin County. The 1972 Agnes Flood destroyed all but three of the county bridges. In 1978, Henninger Farm Covered Bridge was listed on the National Register of Historic Places.
