The Vanderwarker Tunnel was part of the Marietta and Cincinnati Railroad's line that connected Marietta to Cincinnati. Under the direction of local landowner Thomas W. Moore, workers began carving the tunnel in 1855. It opened in 1865 and trains continued to pass through it until 1924, when part of the structure collapsed. Today a stream has reclaimed its course through part of the tunnel and not much physical evidence remains. However, the nearby community, named Tunnel because of the Vanderwarker Tunnel, serves as a reminder.
