In service from 1877 to 1963. This tunnel was also the meeting place for north and south bound track crews during the construction. T15 was in the group of latest surviving tunnels on the CNO&TP. In 1961 Southern Railway drew up plans in cooperation with the City of Cincinnati, Ohio to completely bypass this tunnel via the current New River viaduct a few miles north/west of here. On July 9th, 1963 around 11:30pm the last train rolled through Tunnel 15. On July 10th, 1963 at 12:04am the first train rolled over the New River viaduct. The tunnel has sat here ever since.
It is eligible for the National Register of Historic Places due to its significance of being the meeting place of the construction of the rail line. However, time is running out. The potential for a bicycle/walking trail is there...but the tunnel is running out of time. Severe damage to the south portal is very evident from weather damage. The bore itself is stable, but the linings need work. Floor has sustained severe damage from water flow and garbage dumping by local vagrants.

- Potential for a bike/pedestrian pathway or trail between Robbins and Helenwood, TN. No plans for such idea are on the table at this time.
- Bored in 1877, lined and finished in 1879. Cincinnati construction crews and Chattanooga construction crews met with the building of the tracks in the center of this tunnel.
