For the most part, these suspension footbridges appear like the sidewalk outside a typical residence in that only one was posted with a "No Tresspasing" sign while another had "Walk At Your Risk" sign.
The map associated with this listing shows the location of the first one. The remaining seven are as one would work their way downstream on the Cane River in a predominately northeastern direction. Coordinates for all eight are below.

Immediately upstream a mile and a quarter from the first of these eight suspension footbridges is an NCDOT suspension footbridge listed here: http://bridgehunter.com/nc/yancey/bh63495/
