Benjamin H. Latrobe, Jr.

Benjamin H. Latrobe, Jr.

One of two brothers who spent most of their professional careers working for the B&O Railroad during several decades of the 19th century,. Benjamin, originally trained as a lawyer, became America’s pioneer railroad engineer. One of his many notable construction projects was the design of the famous Thomas Viaduct across the Patapsco River Valley at the beginning of the Washington Branch connecting the mainline of the B&O with the nation’s capital. Upon completion in 1835, the 700 foot long stone bridge was the largest in the United States. It was also the first bridge in America built with a curving alignment, an engineering marvel at the time. The Thomas Viaduct contains 63,000 tons of granite, and stands today as a monument to the skill and determination of Benjamin Latrobe. Trains continue to rumble across the 66 foot high span today.
