SHREVEPORT, La. (KTAL/KMSS) — Before phones and the internet, the Pony Express helped deliver letters and news across the United States.

The mail service began in 1860 and used riders on horseback to carry messages between Missouri and California. A trip that once took weeks could be completed in about 10 days.

The Pony Express only lasted about 18 months before the telegraph replaced it, but it became a symbol of determination and the country’s westward expansion. Today, it remains an important part of American history.
