One of the most historic of bridges in the US a person should visit is the Thomas Viaduct. The viaduct features eight spans of stone arch (each one has a span of 58 feet or 18 meters) with a total length of 612 feet (187 meters). It’s 59 feet in height. Built in 1835, it was named after Philip Thomas, the first president of the Baltimore and Ohio Railroad Company, which had built, owned and operated the viaduct. The bridge’s last rehabilitation project happened almost 90 years ago. Since then, it has been in use with no known repairs done to it. The bridge can be found in Maryland, between Elkridge and Relay, along the Patapsco River.

The rest of the story and photos can be seen in this film produced by an avid railroader. Produced in 2019, this narrator shows you all the views of this gorgeous viaduct while telling you some more interesting facts about it.  Hope you enjoy it! 🙂
