Bridge Documentation

View Archived National Bridge Inventory Report - Has Additional Details and Evaluation

This is an attractive and fairly long surviving concrete arch bridge. It has attractive architectural detailing on the spandrel walls and retains original solid parapet type railing. It also has a single sidewalk. The sidewalk is not cantilevered. The sidewalk also includes a low-level railing that separates the sidewalk from the traffic lanes, which appears to be an original detail, and therefore unusual, since such railings were not normally included on bridges built during this time. The bridge appears to retain excellent historic integrity.

Do not be misled by the outdated assessment of Pennsylvania's Historic Bridge Inventory, which claims that this bridge is common. Concrete arch bridges in excess of two spans that also retain good historic integrity including original railings are anything but common. This should be considered a noteworthy bridge.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The 5 span, 650'-long reinforced concrete deck arch bridge built in 1922 is supported on concrete piers and abutments. The spandrels are paneled to accent the arches. It has paneled parapets and paneled pilasters at the piers. A concrete railing separates the roadway from the sidewalk. Built as a joint-county project using a design prepared by the county engineers, the bridge is an example of a very common bridge type/design with no unusual or distinctive features. Statewide, over 200 examples from before 1916 survive, and 270 reinforced concrete closed spandrel arch bridges predate 1920. The bridge is not historically or technologically distinguished by its setting or context.

Discussion of Surrounding Area

The bridge carries a 2 lane highway with a sidewalk over the Juniata River near its junction with the Susquehanna River. The bridge spans between Perry and Dauphin Counties. At the west end of the bridge is a campground. At the east end of the bridge are two concrete block commercial buildings (ca. 1950) and the intersection of US 322 and SR 849. The setting does not have the integrity or cohesiveness of a historic district.

Bridge Considered Historic By Survey: No
