- Talks of a rails to trails type project have been pitched around for several years according to a few local residents. Allegedly, this has not happened because Norfolk Southern does not want to install a pedestrian crossing to link Tunnels 23 and 24.
- Built in 1878 by the Cincinnati, New Orleans & Texas Pacific Railroad in cooperation with the city of Cincinnati, Ohio

- Tunnel of the bare rock bore variety. The tunnel never had portals nor any kind of lining. This is because it is bored through solid limestone and sandstone. The lease agreements with the CNO&TP specified only bores with a mix of shale, slate or clay in them had to be lined.
