Prescott to Jerome

SR 89A's southern terminus is at a junction with SR 89 north of Prescott near the Antelope Hills Golf Course and Ernest A. Love Field.^[6] The road heads east from the junction with SR 89 as the Pioneer Parkway, a four-lane divided highway with diamond interchanges at most intersections. It continues as a divided highway until it reaches Fain Road in Prescott Valley.^[7] The route continues beyond this intersection as a two-lane undivided highway.^[1][8] The only at-grade intersection in this stretch is a junction with Great Western Drive, near milepost 321.^[1]

SR 89A north of Cottonwood

As SR 89A moves to the northeast, it begins to ascend the Black Hills mountain range.^[1][8] ADOT has designated this section of SR 89A as the Mingus Mountain Scenic Road by ADOT.^[9] The roadway follows the terrain through a series of hairpin turns as it climbs in elevation. Once SR 89A reaches passes over the mountains, it begins its descent into the Verde Valley. During its descent, SR 89A enters the town of Jerome. In Jerome, the highway provides access to the nearby Jerome State Historic Park.^[1][8]

Jerome to Sedona

Upon exiting Jerome, SR 89A heads northeast through the Verde Valley.^[8] The highway also picks up the Historic US 89A designation on the south end of Jerome. Officially named the Jerome-Clarkdale-Cottonwood Historic Road by the Arizona Department of Transportation, Historic US 89A is one of only four state designated historic routes in Arizona, the others being Historic Route 66, Historic U.S. Route 80 and the Apache Trail Historic Road.^[9][11] The historic route was designated on May 13, 1992 by ADOT and is about 10 miles long.^[12]

After SR 89A and Historic US 89A enter the town of Clarkdale, SR 89A turns southeast at a roundabout with Clarkdale Parkway. The route continues toward the southeast through Clarkdale before entering the town of Cottonwood. There, the highway starts heading east at Cottonwood Street before reaching an intersection with Main Street.^[1][8]

Historic US 89A, runs through the old downtown areas of both Clarkdale and Cottonwood. From the present day traffic circle between SR 89A and Clarkdale Parkway, Historic 89A continues north along Clarkdale Parkway, turning right at Main Street in Clarkdale, and then right again at Broadway. It continues past Tuzigoot National Monument, becoming Main Street in Cottonwood, and providing access to Dead Horse Ranch State Park. The route intersects Cottonwood Street, where the bypass route now intersects Main Street.^[9][8]

SR 89A in Sedona

Following the intersection with Cottonwood Street, the road follows Main Street to an intersection with SR 260, which heads to the south toward Camp Verde and I-17. SR 89A then moves northeastward towards Sedona.^[1][8] As the highway leaves Cottonwood, it again becomes a divided highway north of Rocking Chair Road, heading into desert. Before reaching Sedona, SR 89A provides access to Red Rock State Park.

The route remains a divided highway until it reaches Sedona, an arts and resort community known for its red sandstone formations.^[5] As it enters the city of Sedona, the route is known as the Si Birch Memorial Highway. The route continues east through Sedona, providing access to the Sedona Airport.^[13] SR 89A continues toward the east through Sedona to an intersection with SR 179, which heads south from this intersection through the southern part of Sedona to provide access to I-17.^[1][8]

Sedona to Flagstaff

Upon leaving Sedona, SR 89A becomes the state designated Sedona–Oak Creek Canyon Scenic Road.^[9] The highway heads northeast into a wooded area from Sedona and follows Oak Creek as it enters Oak Creek Canyon. SR 89A then curves to the north as it follows the creek and provides access to Slide Rock State Park along this portion of the highway. The roadway leaves the creek as it begins to ascend through the canyon. At the edge of the canyon, the Scenic Road designation ends.^[14][8]

Upon ascending, the road goes through a series of hairpin turns (no trucks over 50 ft.) toward the Mogollon Rim. The roadway continues northward away from the canyon towards Flagstaff. It curves northeastward as it passes to the west of the Forest Highlands Golf Club. The route continues to the northeast towards I-17 near Flagstaff Pulliam Airport.

SR 89A begins to run concurrently with I-17 as a freeway northward. The two highways continue north to an interchange with I-40, where I-17 terminates. The route continues north along Milton Road, to the west of Northern Arizona University before reaching its northern terminus at I-40 Business in Flagstaff.^[1][8]
