The Old Stone Arch is a stone arch bridge along the former route of the National Road in Marshall, Illinois.

The National Road, the most-traveled U.S. road in the early 1800s and the first built by the U.S. government, connected Illinois to the Eastern United States and helped bring settlers and goods to the state during its early years.

The bridge has served road traffic continuously since its construction and was part of U.S. Route 40 from the route's creation to 1953.

[2] The bridge was added to the National Register of Historic Places on February 20, 1975.
