==Route description== Loop 121 begins at an intersection with FM 439 near Belton Lake. The highway travels through more rural areas of the city, running near the western edge of Belton and passes just east of the campus of University of Mary Hardin Baylor. Loop 121 travels through more commercial areas between I-14/US 190 and I-35 as the highway passes near the Bell County Expo Center. East of I-35, the highway travels through a more suburban area of Belton before ending at an intersection with FM 436.
==History== Loop 121 was first designated as '''Spur 121''' on May 29, 1941 as a highway in Brewster County, connecting SH 227 (now FM 170) to the town of Terlingua. This highway was cancelled on February 20, 1946, being removed from the state highway system.
Loop 121 was designated on October 31, 1958, running from I-35 eastward to FM 436. On October 11, 1978, the highway was extended west of I-35 to US 190, absorbing FM 594.<ref>{{TxDOT|FM|594|accessdate=January 27, 2018}}</ref> Loop 121 was extended northward from US 190 to FM 439 on July 10, 1988, absorbing FM 3467 in the process.<ref>{{TxDOT|FM|3467|accessdate=January 27, 2018}}</ref>
