Ricochetrider Posted December 22, 2023 Share Posted December 22, 2023 The Rockville Bridge crosses the Susquehanna River, just north of Harrisburg. It’s the longest stone masonryarch railroad viaduct ever built,[2] at 3,820 feet (1,160 m). It has 48 70-foot spans.[2] The bridge was listed on the National Register of Historic Places in 1975 and was designated as a National Historic Civil Engineering Landmark in 1979. 13 1 Link to comment Share on other sites More sharing options...

I’ve wondered if you were somewhere nearby, I’m in Camp Hill. I ❤️ the Rockville Bridge. 1 Link to comment Share on other sites More sharing options...

Whoa, very cool. This is reminiscent of bridges I’ve seen in Reading & Allentown, among other places in PA. Gotta make a road trip out to see this. 1 Link to comment Share on other sites More sharing options...
