Danville, Virginia has a vibrant railroad past, and it still has a passenger Amtrak line and busy Norfolk Southern freight line which pass through; Amtrak being a nice way to travel to New York City to the north, or New Orleans to the south. The first image below is the concrete arch railroad bridge crossing the Dan River. There are several auto and truck traffic bridges across the river at Danville as well.
The bridge which has always attracted my attention, however, is the original, steel-truss, Civil War era railroad bridge, that has been converted into a walking, biking and jogging path, for thousands of people annually. The details of the old bridge have always been of interest to this (not so old really) Army Engineer, and I suspect there are many just like me with the same opinion. Enjoy seeing what I saw.
