Bridges are the oldest transportation structures ever known, trans-versing difficult terrains from plains, hills to water bodies. Simply no river has ever been too wide for feats of engineering to demonstrate their technological prowess. Bridges are not only known for transportation but also for international trade.

The first bridge was called Charles Carrollton bridge because he lay the first stone of the rail bridge. This bridge was the first masonry railroad bridge, designed as a two-arch stone bridge by Casper Wever.
Part of the bridge spans the Gwynns Falls while the rest crosses a wagon road. This bridge was completed in the year 1829 and started operating in 1830 on New Year’s Day. This became the first United States’ rail road destination.
In fact, it was already termed as a historic civil engineering landmark by the year 1982. Flashing forward seventy years later, it remains to be the oldest standing structure with the capability of carrying modern high-speed trains with ease.
Causey Arch

The Causey Arch is also known as Tanfield Arch, built in 1727, most people term it to be the oldest rail bridge still in existence.

Being a single span bridge at 105′ wide and 85′ high, it was termed as the largest in the country for 30 years.
Wood was used to build the rail road but there was the fear that it would collapse just like the one built in 1725. Later, in 1739 the Arch was destroyed and reinforced in 1980s, still in use till date.
