Description 

Significance: The South High Street Bridge is one of four surviving lenticular truss bridges in the Commonwealth of Pennsylvania and one of fifty remaining in the United States. The truss derives its name from the lens shape created by the upper and lower chords of the span. This 80'-9" bridge is typical of the early polygonal pony truss designs patented by William O. Douglas and built by the Berlin Iron Bridge Company of East Berlin, Connecticut. The Berlin Iron Bridge Company was the main producer of this unusual truss form, which was erected in many rural and urban settings throughout the United States between 1878 and 1900.
