Long Description:

The plaque reads:

National Historic Civil Engineering Site

BLACKFRIARS BRIDGE

A tribute to the civil engineers, contractors, and workers who designed, fabricated and erected this bridge to maintain an important social, political, and economic link between London and Petersville. The bridge is a rare survivor of the through arch-truss form fabricated by the Wrought Iron Bridge Company of Canton Ohio. The original pedestrian design loadings are consistent with those specified in modern codes. The centre four truss panels feature a double-panel diagonal configuration that was patented in America one year after the bridge opened on 27 September 1875. Blackfriars Bridge has also been woven into the cultural fabric of London.
