The road then goes through the hilly terrain of Jackson County, and runs past Annville and reaches US 421 at Tyner.

At this point, the road is no longer a standard highway and runs as a concurrency to the northern part of Tyner, where it goes east towards Mummie.

From here, the road curves and goes into the town of Jackson where it then goes on another curvy route into Magoffin County where it meets its eastern terminus in Salyersville.

Work has been done to improve the route of KY 30, to establish it as a corridor between London and the impoverished areas the road currently runs through.

In a separate segment, a new ~7 mile alignment was constructed in Owsley County between Levi and Travellers Rest.
