US 89A runs near or through Lee's Ferry, the Navajo Bridge, Vermilion Cliffs, the Kaibab Plateau, and Fredonia, Arizona.

From Jacob Lake, Arizona State Route 67 (AZ 67) branches off south, leading to the North Rim of Grand Canyon National Park.

It is also during this time that a new alignment for US 89 was constructed to serve the Glen Canyon Dam, with SR-11 being now signed as US 89A south of Kanab and US 89 to the north.

As part of the 1977 Utah state route renumbering to conform signage and legislative definitions, SR-11 was truncated to what is now signed US 89A.
