Route description
SR 91 is a two-lane highway that travels through rural areas of Cullman County. Although it is signed as a north–south highway, the first 8 mi of the highway from its southern terminus actually travels in southeasterly direction. In Arkadelphia, the highway takes a virtual 90-degree turn to the left and assumes a northeasterly trajectory, which it maintains for the duration of its length.

SR 91 has an interchange with Interstate 65 (I-65) approximately 11 mi southwest of Hanceville, and provides a connecting route for motorists heading to and from this town. Our Lady of the Angels Monastery, founded by Mother Angelica, is located near SR 91 between I-65 and Hanceville.

Much of the highway between Wilburn and I-65 is a narrow winding road through hilly rural terrain. In some places, the road is actually substandard for it to be a numbered state route. However, from I-65 north and east, the roadway is substantially better and contains less sharp turns and short sightlines.
