Built in 1889 by the Berlin Bridge Company of Connecticut, this wrought iron bridge is a rare surviving example of the pin-connected lenticular truss design used for iron bridges from 1880 to 1890. It originally spanned the Ham Branch at the end of Delage Farm Road in Franconia from 1889 to 2001, carrying horse-drawn wagons over a narrow river to serve the Delage Farm. The Dow Bridge, a mile southeast on Main Street, shares the same rare design. Restored for modern use, the bridge was saved for viewing here through the cooperative efforts of the Franconia Board of Selectmen, the Conservation Commission, the Franconia Area Heritage Council, and contractor David Presby.
