SEPTA - Wissahickon Creek Viaduct
This stone bridge made of Talcose slate spans Wissahickon Creek just north of the Ridge Avenue Bridge in Philadelphia,PA.
Two tracks occupy the viaduct that the Nolan & Brothers completed in 1881 and 1882 for $375,000, a figure which accounted for the foundations already constructed. The only repair on record is in regards to iron tie rods done in 1930.
While the creek only flows beneath one span near the western end, the entire length is necessary to span the wide PHILADELPHIA & READING valley. The park's Lincoln Drive passes under two spans near the eastern end.
The five main arches each span 70'-0" long, with a rise of 23'-0", between piers 9'-6" wide at the spring line. At each end, two l0'-0" arches reduce the volume of masonry in the abutments.
Interesting to note is that P&R Chief Engineer William Lorenz's name appears first on the builder's plaque; however, his assistant C. W. Buchholz apparently deserves credit for the design.
