The HAER Documentation (attached) provides explanation. It is both aesthetic and also for reducing dead weight. In a sense you might think of an open spandrel arch bridge versus a closed spandrel arch. Perhaps bridges such as these were the first attempts to reduce the amount of material needed in an arch. As the documentation correctly notes, other examples of similar arch bridges (albeit often with half-circle openings) can be found overseas. I am aware of examples in Europe and China. https://en.wikipedia.org/wiki/Pont_du_Diable_(C%C3%A9ret) http://armchairtravelogue.blogspot.com/2009/08/more-bridges-...

Iíve never seen pierced spandrels like this, so I canít comment to the true reasoning behind them. However, they could possibly be purely decorative, or reduce the total dead load on the arches by reducing the amount of material supported.

This mornings paper where I live has a picture of this bridge on the front page concerning fishing on the schuylkill river.My fiancee asked me about the pierced spandrels which I told her i don't know why they were built into the bridge.Out of curiosity does anybody know why there are pierced spandrels built into this bridge and if it's for structural integrity?

Did anyone know that about 1.5 miles up the train line is a smaller 3 span bridge over Washington Rd and a small creek that is the same architecture as the Peacock bridge? It looks identical but smaller. How cool is that ?!?!
