Bog Bridge

Bog Bridge, also known as the Cilleyville Bridge, is a historic covered bridge in Andover. Built in 1887 and located off New Hampshire Route 11 west of Andover center, the Town lattice truss bridge is one of New Hampshire's few surviving 19th-century covered bridges, and is relatively little altered since its construction, having had its roof replaced and an abutment reconstructed.
