Kentucky Route 9 (KY 9) is a 116.285-mile-long (187.143 km) state highway maintained by the Kentucky Transportation Cabinet in the U.S. Commonwealth of Kentucky. The highway extends from Grayson to Newport (a city in Kentucky across the Ohio River from Cincinnati, Ohio), roughly paralleling the Ohio River between Vanceburg and Newport.
Most of its path, from Grayson to the Interstate 275 loop in Wilder, is also known as the AA Highway (officially, the "John Y. Brown Jr. AA Highway"). KY 10 forms a branch of the AA Highway between Vanceburg and the Jesse Stuart Memorial Bridge in Grays Branch, near Greenup.
The AA Highway follows a general northwest-southeast orientation. For most of its length, the AA Highway is a two lane road that passes through a sparsely populated rural area of Northern Kentucky. While the highway passes through terrain that is rolling to hilly, the highway is generally level with moderate grades and no steep grades. Except for Carter County, all counties that the AA Highway passes through border the Ohio River. The only municipalities on the highway are Vanceburg and Maysville and suburban areas of Cincinnati at its western terminus. Those areas are also the only areas with any services used by motorists such as motels, gas stations, restaurants, convenience stores, etc. The only traffic signals on the AA Highway are near Maysville (along a commercial strip with many retail establishments and restaurants), suburban Cincinnati, and at its eastern terminus just north of Interstate 64 near Grayson. There are no rest areas on the AA Highway. Other than the portions that traverse the edge of Maysville and enter suburban Cincinnati, there are no shopping centers or major retail stores along the AA Highway.
While the AA highway is not an expressway, it nonetheless serves as the shortest highway link between Cincinnati and Ashland, Kentucky. As such, it provides a link between Cincinnati and other Midwestern cities such as Chicago, Indianapolis, and Dayton and cities south and east of Ashland such as Huntington and Charleston in West Virginia, Charlottesville and Richmond in Virginia, and Charlotte and Winston-Salem in North Carolina.
The AA Highway is a rural two-lane highway for most of its length and traverses through some desolate terrain. Driver inattention and speeding, in combination with the numerous side road entrances and at-grade intersections have made it a dangerous and deadly road. To address these issues, guide signs comparable to interstate-styled signs have been installed along the highway at major intersections, along with additional overhead lighting. Other measures to improve safety and increase capacity are under consideration.
Construction began in 1985 on the first segment of the AA Highway. Estimated to cost $266 million to complete, it was designed primarily as a two-lane controlled-access facility. The first phase included the construction of 86 miles (138 km) of the AA Highway from the junction of Interstate 275 and Licking Pike (existing KY 9) in Campbell County east to Vanceburg. The first phase also included the design of two twenty-five mile-long spurs running east from Vanceburg, one ending at US 23 near Lloyd and the Jesse Stuart Memorial Bridge, the other ending near Interstate 64 in Grayson.
When construction began, the costs for the first phase had risen to $292.7 million; the state had sold $300 million in bonds to pay for it. Segments of the highway, from Clarksburg just west of Vanceburg to Tollesboro was routed on an earlier relocated alignment of KY 10.
It officially opened in 1995, however, it was not formally dedicated until 2003.
The AA Highway including the Greenup spur was originally designated as KY 546, and the Grayson spur was signed as KY 694. On May 26, 1988, the designation, "AA Highway," was proposed to be signed along with KY 546 and KY 694. A few years later, this designation was put in place with the AA Highway being co-signed with KY 546 and KY 694, however, many motorists were soon confused by the ever-changing designations.
To solve this issue, the AA Highway was renumbered in late 1995. The AA Highway including the Grayson spur was renumbered KY 9, and the Greenup spur was renumbered as KY 10. KY 10 also overlaps portions of the AA Highway throughout the entire highway's existence. Old KY 9 in Campbell county was renumbered as KY 915, and old KY 10 between Vanceburg and South Portsmouth was redesignated as KY 8.

The Kentucky Transportation Cabinet is proposing widening and correcting some deficiencies and addressing growing traffic concerns along the AA Highway from its western terminus near Covington to Maysville. Several options are being considered, such as: removing some of the at-grade intersections, widening to four lanes from two with partial control access, and full control access.
The AA Highway widening study was undertaken. Many residents and users of the road were concerned about intersection safety, while others discussed the high volume of traffic and the lack of passing lanes. Four alternatives were considered:
Two median types were considered: a concrete barrier wall and a depressed grass median. Mountable medians in rural areas are not recommended. With each median type option, there would be 12-foot (3.7 m) travel lanes and 12-foot (3.7 m) shoulders. The depressed grass median would be 40 to 60 feet (18 m), separating the two opposing traffic flows effectively. Due to the high speed of travel, access control with a minimum of 12,000 feet (3,700 m) is recommended for the limited access alternate.
Also under consideration is using the existing alignment of the AA Highway as the eastward continuation of Interstate 74 from Cincinnati to Grayson, where it would connect with Interstate 64. This would necessitate adoption of Alternate Four described above.
