Cilleyville-Bog Bridge
No. 16
Built in 1887 by Prentice Charles Atwood for $522.63, the Cilleyville-Bog Bridge originally was known as the Bog Bridge. After the nearby Cilleyville Bridge burned in 1908, it became known as the Cilleyville Bridge. The 61-foot Town lattice truss spans Pleasant Brook and is notable for its distinctive tilt, which local legend attributes to timbers intentionally cut short by members of the construction crew.
After decades of deterioration, the bridge was closed in 1997 and temporarily suspended above the brook in 1999 while the community raised funds for its restoration. Barns and Bridges of New England, working with Hoyle, Tanner & Associates, completed the rehabilitation in 2002-2003. About half of the original latticework was retained, along with other historic materials, while the roof framing and abutments were reconstructed. The bridge reopened in July 2003 and received a New Hampshire Preservation Alliance award for outstanding restoration and stewardship that year.
It has been permanently closed since 2024 pending further repairs.
