The middle schooler in our group was learning about bridges for a school project. Her teacher shared with her that the Sewickley Bridge built in 1911 and replaced in 1981 had four finials that were saved and placed in four different locations for public viewing. One in Sewickley Village, one in Sewickley closer to the Ohio River, this one across the river near the Coraopolis Library, and one along a different river, the Monongahela River, in Station Square, across from downtown Pittsburgh. We went on a hunt one afternoon to find all four and place a geocache nearby each of them. This is the third.
