Perspective
US 421 did not have any presence in Kentucky until it was extended into Kentucky and Indiana at one point between 1939 and 1957, probably in the late 1940s or early 1950s.[7] When US 421 was designated into Kentucky, it was routed onto the following existing routes:
- KY 66 from the Virginia state line to Harlan,[8]
- KY 257 from Harlan to Hyden,
- KY 80 from Hyden to Manchester,
- KY 21 from Manchester to Big Hill,
- KY 169 from Big Hill to Richmond (including US 25 concurrency),
- KY 50 from downtown Lexington to Frankfort,[8] and
- KY 37 from Frankfort to the Indiana state line at Milton.[9]
Current statuses for original assignments of pre-existing routes
- KY 37 now runs from Gravel Switch to Junction City to Danville, in Marion and Boyle Counties in Central Kentucky.
- The remainders of KY 21, KY 169, and KY 257 still retained their original alignments off the current US 421.
- KY 50 no longer exists in the state route system.
- KY 66 is now assigned to a road in Bell, western Leslie and eastern Clay Counties in southeast Kentucky from Middlesboro to US 421/KY 80 near Big Creek
