It ran on the northern part of the Nashville downtown loop from 1965 to April 7, 2000.

[2] The highway started at the western end of the I-40 portion of the downtown loop, at I-40 exit 208.

It then crossed the Cumberland River on the Lyle H. Fulton Memorial Bridge and ended at an intersection with I-65 and I-24.

The auxiliary route formed traffic problems on the loop as people preferred the main I-65 route over the auxiliary loop.

In 2000, the designation was eliminated as I-65 was rerouted on the northwest and southwest parts of the downtown loop in an attempt to combat traffic issues.
