The Thomas Viaduct built for the Baltimore and Ohio railroad between July 4, 1833, and July 4, 1835 is still standing today, after 179 years. It continues to carry the mainline of the CSX between Baltimore and all points south. It was the first multi-span curved stone arch bridge in the US. Not visible in this photo, it consists of 8 arches and is about 600′ from end to end.
