Tunnel 21 was bored in 1878 through a small mountain at Lancing, Tennessee. It was one of the first tunnels to be bypassed, eliminated or raised. It was eliminated through a process called day-lighting, where the roof was simply blown off and a cut made. This is said to have occurred in 1903. The tunnel was allegedly 347 feet long, of course, these are pieces of data so old and nearly lost they are sketchy as far as accuracy is concerned. Other early bypasses/eliminations were Tunnel 6 in Kentucky and Tunnel 27, the last "Rathole" located in Harriman, Tennessee. You may get to this tunnel by taking the adjacent road, and then sliding down into the ditch next to the current tracks. A small portion of the original tunnel lining remains. Be watchful of trains and please stay off the tracks.
