This bridge is painted an unusual purple color. It is a representative example of a standard plan bridge design that was built throughout Pennsylvania with frequency from 1920-1941. The practice of building these bold and attractive structures would ensure that no drive on a Pennsylvania highway would be without something interesting to look for decades to come. Now, as these bridges begin to age, it is time to re-evaluate these bridges to recognize their increasing rarity as PennDOT moves to demolish many of them, and seek their preservation. They are strong, sturdy structures that if preserved would continue to be viable for decades to come. The East Troy Bridge is a perfect example.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The single span, 192'-long riveted Parker thru truss is supported on concrete abutments. The top and bottom chords are built-up members. Rolled beam sections are used for the vertical and diagonal truss members. Rolled floorbeams and stringers support the concrete deck, which was replaced in 1988. Concrete barriers were constructed at that time, and numerous repairs to the steel truss were made. The 1941 bridge is a late and altered example of its type, which was widely used since the late 1920s throughout the state. Promoted in the 1910s and 1920s as the Roosevelt Highway, one of many tourist trails in the state, the highway was designated as US 6 in 1928, and named as the Pennsylvania section of the Grand Army of the Republic highway in 1948. US 6 has never been a principal east-west road. It is noted for its scenic vistas and low traffic volumes that has limited post-World War II improvements. The highway itself is not a historic district.

Discussion of Surrounding Area

The bridge carries a 2 lane state highway, US 6, over a stream east of the village of East Troy. The setting is predominantly wooded, and it does not appear to have historic district potential. Developed beginning in the early 19th century, SR 6 became part of the state highway system in 1911 and was improved to state standards in the 1920s. The highway itself is not a historic district.
