Pittsburgh, Pennsylvania, is often referred to as the "City of Bridges" due to its numerous bridges that span the city's rivers. With over 400 bridges, it boasts more bridges than any other city in the United States. This unique infrastructure is a result of the city's hilly terrain and the confluence of three rivers: the Allegheny, Monongahela, and Ohio.
The most common materials used in bridge building are generally steel or concrete for larger bridges, and stone or wood for smaller bridges.
