The original  Route 136 was established in mid-1930s as a replacement for Route 106 connecting New Mexico and Colorado, northwest of Chama. This road became U.S. Route 84 (US 84) in the early 1940s. NM 136 was approved and built by the New Mexico State Highway Commission concurrently with SH 178 and Santa Teresa Port of Entry in 1988-1990, and officially opened in 1991. Santa Teresa Port of Entry was opened in 1992 and was designed to alleviate cross-border traffic through other border crossings in central El Paso. Both NM 136 and SH 178 were built to accommodate heavy tractor -trailers and provide ready access to I-10 northwest of El Paso. Leroy Sandoval, former Transportation Planning Division Director, appeared before the New Mexico State Highway Commission and requested the Commission designate NM 136 as the Pete V. Domenici International Highway in honor of New Mexico senator Pete Domenici. The State Highway Commission concurred and approved the designation of NM 136 as the Pete V. Domenici International Highway on May 14, 1998, and appropriated $16,000 to erect signs for the new road name.
