Pennsylvania Overview

Pennsylvania is a major area of coverage for this website, with a focus on the western part of the state. The region has some of the richest variety and highest quantity of metal truss bridges in the country. Unfortunately, very little effort is being made to preserve these bridges, even the particularly rare bridges, and this region's population of historic bridges is dropping rapidly.
