Ouaquaga Lenticular Truss Bridge

The Ouaquaga Lenticular Truss Bridge extends 343 feet across the Susquehanna River with two identical through trusses featuring a distinctive lens-shaped design.

The Berlin Iron Bridge Company constructed this double-span structure in 1888, incorporating advanced engineering techniques that allowed for longer spans with reduced material usage.

The bridge location near the former Iroquois settlement of Onaquaga connects the structure to the Native American presence in the Susquehanna River Valley.

While closed to vehicles since 2008, the bridge remains accessible to pedestrians, offering opportunities to examine its metal 10-panel pin-connected construction.

The bridge incorporates a 13-degree skew in its design, requiring complex engineering solutions that demonstrate the technical capabilities of 19th-century bridge builders.
