This bridge is a good example of a state designed highway plate girder. While plate girders are common nationwide on railroads, some states did not build hardly any highway plate girders. Pennsylvania however, is one state that did build a fair number. This bridge retains good historic integrity including original lattice railings on the sidewalk. New Jersey barriers have been added to the inside of the girders.
Information and Findings From Pennsylvania's Historic Bridge Inventory
Discussion of Bridge
The skewed, 3 span, 204'-long thru girder bridge with floorbeams is supported on reinforced concrete abutments and piers. The bridge has a steel grid deck. In 1983 concrete safety shape barriers were added to the inside face of the built-up girders. A sidewalk with lattice railings is cantilevered from the downstream side of the bridge. The bridge was built in 1929 by the state highway department. The altered thru girder bridge is an example of a very common bridge type that was in widespread use from the mid-19th century through the mid- 20th century. Neither the bridge nor its setting or context are historically or technologically significant.
Discussion of Surrounding Area
The bridge carries a 2 lane road and a sidewalk over the East Branch of Brandywine Creek south of Downingtown. Near the bridge are some late-20th century industrial buildings. A pin-connected deck truss viaduct on high masonry piers carries Conrail (old Pennsylvania RR) over the creek and the highway above the bridge. The railroad bridge and the thru girder highway bridge are not historically or structurally associated.
