On the south side of the Canyon, the phone line left the South Rim developed area near Bright Angel Lodge, went down Pipe Creek, and crossed the Colorado River.

On the north side, the phone line followed Bright Angel Creek up to the rim to the Wylie Way Tourist Camp before the construction of the Grand Canyon Inn.

The line extended for 18 miles (29 km), paralleling the Bright Angel Trail and the North Kaibab Trail, providing a direct link between the North and South Rims, as well as the Inner Canyon.

[1] Only small portions of the cable are currently in use after a Digital Subscriber Line (DSL) circuit to Havasupai Garden was disconnected and the signal moved to a Starlink connection.

The National Park Service awarded US Park Ranger Elizabeth "Betsy" Aurnou the 2023 NPS Wright Brothers Aviation Award for her efforts in removing this historic telephone line from the Grand Canyon.
