1869

Spanning the Little Patuxent River is the sole surviving example of the bridging system invented, 1850, by Wendel Bollman, Baltimore engineer. It was the first system, entirely of iron, used by the Baltimore and Ohio railroad and the first in America. Through 1873 the company built about 100 such bridges.
