Significance: The bridge is an excellent example of a widely used bridge type in New Hampshire, a concrete tee beam bridge. Within that category the bridge is unusual due to its continuous tee beams of variable section and significant length. The survival of its original concrete guardrails and curved surface of the exterior fascia of the tee beams is also significant. Built in 1935 as part of a road widening and straightening U.S. Public Works Project, the bridge serves as a major connector on Route 12 from Keene center south to Swanzey. The road and crossing were in place as early as 1805.
