Previously in Texas, the "151" designation was originally used for Spur 151, which was designated on May 18, 1944 from Denison to the southern boundary of the Federal Government Property. Spur 151 was cancelled on May 21, 1946 and instead replaced by SH 75A, which in turn became SH 91 on December 21, 1994. Loop 151 was designated on August 27, 1958 from I-30 to US 82. On January 20, 1966, Loop 151 extended south to US 59. On December 21, 1982, Loop 151 was transferred to US 59, so Loop 151 was reassigned to the old route of US 59. On February 7, 1985, Loop 151 was transferred to SH 93, so Loop 151 was reused for the route from US 59 to Arkansas, its current route.
