Little Wiconisco Creek Bridge

Map 

Description 

FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: The 1 lane bridge carries a 2 lane road over a stream in a rural setting of active farms. Pastures are at each of the quadrants except the southeast quadrant where is located a late 19th century vernacular frame dwelling with replacement fenestration, siding, and large front and rear additions. The setting does not have the integrity or cohesiveness of a historic district.

The one-span 43'-long steel stringer bridge built ca. 1920 has a concrete jack arch deck, pipe railings, and is supported on stone abutments. The stringers are rolled I-beams with jack arch deck formed by corrugated steel pipe, except for the center-line stringer that is back-to-back channels with inverted-V section concrete deck formed by flat sheet metal with timber bracing. The difference in construction suggests that the center-line stringer and deck section are replacement materials (ca. 1950), although available maintenance records do not document the alteration. The bridge has stone wingwalls topped by concrete parapets, which have been cut down to half their original height (ca. 1980). The substructure has numerous repairs including concrete skirts and a replacement concrete wingwall at the northeast corner. The bridge is an altered example of over 4,300 pre-1957 steel stringer bridges in the state, and one of over 110 with the jack arch deck that was popular from the 1910s to the 1930s. Earlier and more complete bridges in the region represent the significance of the bridge type and design. The bridge is not historically or technologically distinguished by its setting or context.
