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

This attractive state standard riveted through truss bridge was lucky enough in 2003-2004 to receive a repainting. The new paint color is a deep, yet vibrant blue color that really helps this bridge's beautiful details stand out. Sometimes a bridge might be painted a more dull color to help it blend in with its surroundings. However it is nice to see a brighter colors used as well, since historic bridges deserve to be noticeable, and a vibrant paint color can help a bridge be noticed. The bridge has cantilevered sidewalks on each side which have a riveted lattice railing with elongated lattice design that is not like the standard found on most state standard truss bridges. The bridge has no significant alterations and thus its historic integrity is good.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The 1936, riveted, single span, 221'-long, Parker thru truss bridge is supported on concrete abutments with flared, stepped wingwalls. Built to a state highway department standard design, the bridge is an example of a common technology with no innovative or distinctive details. It was part of the rebuilding efforts following the devastating 1936 St. Patrick's Day flood. Over 275 bridges, mostly in the western and central portions of Pennsylvania, were destroyed or damaged beyond repair. To replace them the department turned to established technologies like riveted metal truss bridges, which had been used in the state since about 1900. The bridge is neither historically nor technologically significant.

Discussion of Surrounding Area

The bridge carries a 2 lane street over a stream on the south edge of Meadville, southeast of the National Register-listed Meadville Downtown Historic District. The bridge is separated from it by an area dominated by post-WW II commercial and industrial development along SR 19. To the north are a parking lot and a 1960s office building. To the south is a neighborhood of undistinguished, predominantly early 20th century houses with scattered commercial buildings. Most houses have modern siding and altered windows. The area adjacent to the bridge does not have historic district potential.
