Kentucky Route 404

The highway connects mostly rural areas of Magoffin and Floyd counties with Prestonsburg.

It curves to the east-northeast and stops paralleling the branch when it ends.

The highway intersects the northern terminus of KY 1210 (Caney Fork Road) and crosses over Buckeye Branch before it travels through Blue River.

It crosses over Sam Hale and Blue River branches and then enters the far western part of Prestonsburg.

There, it crosses over Middle Creek and meets its eastern terminus, an intersection with KY 114.
