This is the Big Tunnel, located in Tunnelton, IN which is just east of Bedford. This is the East entrance. When railroads were introduced into Lawrence County, the hills presented quite a challenge. Rather than go around one such hill located between Tunnelton and Ft. Ritner, the O&M (Ohio & Mississippi Railway) made the decision to tunnel through, thereby saving about eight miles of track. The hill became known as Tunnel Hill. The resulting tunnel was a 1750 foot-long, man-made cave carved through the solid rock of the hill and appropriately named The Big Tunnel. It is located approximately three miles southeast of Tunnelton on River Road.
