1889 Hopkinton Covered Railroad Bridge over Contoocook River in Contoocook, NH

(Archived Bridge HunterBridge HunterHAERSatellite)

"Built 1889, Washed off abutments and restored 1936 & 1938; Abandoned 1962; Restored 1990; Major rehab 2003; Fire suppression and fire proofing 2009; Removal of center shelving 2017; Erosion control fixes, minor siding repairs, new staining 2019." [BridgeHunter]

"SIGNIFICANCE: "The Contoocook Railroad Bridge is one of eight surviving covered bridge in the United States. It is an excellent example of the double-web Town lattice truss used by the Boston & Maine Railroad in the late nineteenth century." [HAER_data]
They must have forgotten the adjective "railroad" in front of "covered bridge" because I have noted way more than eight covered bridges in the USA.
