Arroyo was a lumber town in western Pennsylvania in the United States that also had an extensive hide tanning industry.
[1] It was founded by Thomas Irwin and located in the township of Spring Creek, on the Clarion River, and 10 miles (16 km) from Ridgway.
[1] The Arroyo Bridge Company was incorporated in April, 1883, with F. Shaffner, E. M. Rogers, C. H. Smith, James B. Wicks and Charles Millen, directors.
[citation needed] Elk County purchased the bridge and replaced it in 1901, when it became the site for many summer social events and dances.
[1] The bridge was such an important structure in the town that dances and parties were held on its deck during Arroyo's heyday.
