In 1995 a massive earth slide dammed the North Fork of the Virgin River in Zion Canyon. The rerouted river destroyed the heavily traveled road on the opposite bank. Interim repairs were made to restore the roadway, including temporary bank stabilization using soil nails. As a permanent solution in 1996, a 22.5-foot tall T-WALL® was used for a new retaining wall to support the repaired section of road.
