High Bridge

This railroad bridge crossing the Kentucky River between Jessamine and Mercer counties is simply known as "High Bridge".

It began in the 1850s as a suspension bridge with stone towers, designed by John A. Roebling (designer of the Roebling Suspension Bridge that takes you from Covington to Cincinnati, as well as the Brooklyn Bridge in NYC). That project went unfinished, however, and its remains were later revised with a cantilever design. At its completion in 1876, it was the first cantilever bridge in the United States and the tallest railroad bridge in the world.

The bridge was modified and expanded greatly in 1911, and then again in 1929. It's still in operation today, serving the Norfolk Southern Railway.
