Pre-1927 Routes - Not a depiction of an actual route marker. Where the route has a common, continuous history with a newer route this symbol will appear with that listing. |
East terminus: Rt. 8 at Pojoaque
1927 designation: NM-4.
Present-day roads along this route: NM-4
This is probably another route that was renumbered in 1927 with a newly available designation to avoid posting a 3-digit number on the original route marker.
No connection with post-1927 NM-101.
Previously --- U.S. 80-85-180 (Main St.) (1960-88)
East terminus: NM-478 at Las Cruces
Previously --- I-25 (exit 1) (1960-2003)
Length: 1.420 mi.
County: Doña Ana
History: Created probably c. 1960 when the first piece of I-25 opened around Las Cruces, along University Avenue on the north side of NMSU. Originally extended south to U.S. 80 at the offramp from I-10. Probably in 1988, extended west to NM-28. In 2003, portion east of Main St. turned back to City of Las Cruces.
Improvements: Two to four lane paved.
Comments: In 1971, there was a U.S. 85 sign posted westbound at the NMSU exit (even though the exit always was marked NM-101). Possibly there was a plan to reroute 85 from I-25 onto this road, then onto Valley Drive. It was never posted any further than this.
North terminus: Rt. 65 E of Mosquero
1927 designation: NM-39.
Present-day roads along this route: NM-39
This was originally the south end of Rt. 39 but this piece was renumbered in the early 1920s as Rt. 102. Rt. 39 was rerouted onto a more westerly route to Tucumcari. It reverted to NM-39 in 1927 and has no connection to NM-102 even though that route was later established in the same general corner of the state.
No connection with post-1927 NM-102
Previously --- NM-18 (1940s-50s); NM-65 (1950s-88)
East terminus: NM-402 N of Amistad
Previously --- Sedan 1940s-50s); Texas State Line E of Sedan (1950s-88)
Length: 46.318 miles
County: Harding, Union
History: Original route, established in the 1940s, ran from NM-18 (402) to Sedan. This was extended to Texas in the early 1950s, and combined in mid-1950s with part of old NM-57 and old NM-171 (S of Bueyeros). In the 1988 renumbering, it also took over the part of old NM-65 (now NM-420) from the junction of 102 to NM-39. The original segment from NM-402 to Texas was renumbered NM-421.
Improvements: Two-lane paved highway
Comments:
| No indication that this number was used in the pre-1927 system. |
West terminus: NM-32 S of Quemado
East terminus: Quemado Lake
Length: 3.9 miles
County: Catron
History: Only shown on the 1995 and later official NM highway maps. Probably established in or after 1988.
Improvements: Two-lane paved highway
Comments:
East terminus: Rt. 3 at Cuervo
1927 designation: U.S. 66.
Present-day roads along this route: NM-156, Cuervo Road
This shows on a 1926 map as the main road east out of Santa Rosa, higher rated than Rt. 3. The original routing of U.S. 66 just east of Santa Rosa was along this road. By the early 1930s, U.S. 66 had been aligned along the more direct former route of Rt. 3.
No connection with post-1927 NM-104
Previously --- NM-65 near Trementina (mid 1930s-1950s)
East terminus: BL I-40 at Tucumcari
Previously --- NM-129 near Conchas Dam (1930s-40s)
Length: 106.897 miles
County: San Miguel, Quay
History: This route was first established in the 1930s to connect NM-65 to NM-129 near Conchas Dam. It was extended to Tucumcari in the 1940s and later overlaid with 65 from their east junction to Las Vegas. In 1988, NM-65 was dropped from the concurrent portion east of Las Vegas.
Improvements: Two-lane, paved
Comments: I'm not sure what the purpose of the overlay with 65 was, since 104 didn't apparently continue independently west of Las Vegas at that time.
East terminus: Rt. 4 at Road Forks
1927 designation: NM-14
Present-day roads along this route: I-10 follows this route closely
This was the connection to what became Arizona 86, and the more direct Rt. 42 (originally Rt. 4), future U.S. 80, southwest of Lordsburg appears to have been a better developed road. Since the original state route numbers appear to have been assigned sequentially as they were created, this road probably was improvevd much later than Rt. 4/42.
No connection with post-1927 NM-105
East terminus: NM-94 at Tierra Monte
Length: 9.1 miles
County: Mora, San Miguel
History: Established in the early 1950s. No changes in this route since then.
Improvements: Two lane, paved
Comments:
East terminus: Rt. 4 at Lordsburg
1927 designation: Probably none
Present-day roads along this route: NM-464(?), NM-92, possibly county roads may approximate the route
This was one of two routes from Lordsburg NW to the Arizona border, the other being Rt. 45. This road shows on a 1926 map as the better alternative to Arizona, but by 1927 U.S. 180 (I) was temporarily routed on Rt. 45 and this road had disappeared from the map. U.S. 180, later 70, was constructed on an alignment between old Rts. 45 and 106.
No connection with post-1927 NM-106
North terminus: Colorado State Line
Length: 11 mi.
County: Rio Arriba
History: Established early-mid 1930s as one of several routes that connected New Mexico and Colorado northwest of Chama, prior to extension of U.S. 84. This was actually the main route from Chama to Colorado in the early 1930s, and the designation for this route is not evident from this time period. Removed from state system within a few years
Comments:
North terminus: NM-76 at Española
Previously --- NM-68 (1980s-88)
Length: 0.752 mi.
County: Santa Fe
History: Established 1980s, originally ran to NM-68 along what is now NM-583. That segment renumbered in 1988.
Improvements: Two lane, paved
Comments: Runs along the extension of La Mesilla Road (south of 84-285 it is NM-399) through the hamlet of Sombrillo.
North terminus: Rt. 3 at Alamogordo
1927 designation: Probably none
Present-day roads along this route: No established roads appear to exist.
This was a road that essentially paralleled Rt. 50 to its east, south of Alamogordo.
No connection with post-1927 NM-107
North terminus: US-60 at Magdalena
Length: 41.722 mi.
County: Socorro
History: Established on essentially this alignment in the mid-1930s.
Improvements: Mostly a gravel road
Comments:
East terminus: Rt. 19 at Scholle
1927 designation: U.S. 70
Present-day roads along this route: U.S. 60
Appears to have been established as a more direct route from Mountainair to Socorro via Rt. 9. After 1927, the road was extended westward to join with U.S. 85.
No connection with post-1927 NM-108
North terminus: NM-19
Previously --- Hollene,early 1950s; NM-93 nr. Bellevue, mid-1950s-1980s
Length: 23.38 mi.
County: Curry
History: Established early 1950s, extended northward by the mid-50s as far as NM-93, then truncated at NM-19 in the 1980s.
Improvements: 2-lane, paved road
Comments: Runs just west of and parallel to the Texas state line
North terminus: Rt. 19 at Willard
1927 designation: NM-41
Present-day roads along this route: Northernmost portion does not correspond with any established roads; the southernmost part may include part of NM-55
No connection with post-1927 NM-109
North terminus: NM-309 E of Belen
Length: 7.757 mi.
County: Valencia
History: Appears to have been established around 1980.
Improvements: Two-lane, paved
Comments:
East terminus: Rt. 13 at Picacho (via Hope)
1927 designation: NM-33, NM-34
Present-day roads along this route: U.S. 82, Picacho Road
By the early 1930s, this was part of NM-83 west of Hope.
No connection with post-1927 NM-110
Previously --- U.S. 84 near Canjilon
East terminus: NM-554 at El Rito
Length: 3.798 mi.
County: Rio Arriba
History: This route, 100 and 111 have a little bit of an intertwined (and unclear) history. In the 1930s, this designation may have been assigned to what became NM-100 from Vallecitos to Tres Piedras, and 100 may have extended over what became this route east of Canjilon. In the mid-1930s, 110 extended from Vallecitos to NM-74 (U.S. 285) at Tres Piedras. By the 1940s, it was moved onto the route beginning near Canjilon and terminating at its present location. In the 1980s, the road from west of El Rito to Canjilon was removed from the state highway system and became a NFS road. West of Canjilon, it became NM-115.
Improvements: Existing portion of the state route is paved.
Comments: Its southern terminus, NM-554, was originally part of NM-96
Previously --- (west terminus) NM-74/U.S. 285 at Tres Piedras (1930s-40s)
North terminus: Rio Arriba County Rd. 450 at Cañon Plaza
Previously --- (east terminus) NM-3 at Arroyo Hondo (1930s-74).
Length: 19.519 mi.
County: Rio Arriba
History: Originally, this number was assigned in the 1930s to the route from Tres Piedras to Arroyo Hondo. It was extended south to Vallecitos and further south along its current alignment to U.S. 285 in the 1940s. In 1974, U.S. 64 replaced the original part of this route between U.S. 285 and NM-3 (522).
Improvements: Existing portion of the state route is paved.
Comments:
East terminus: Rt. 3 at Tularosa
1927 designation: NM-52
Present-day roads along this route: Road closed to public through White Sands Missile Range
This was a direct extension of Rt. 26 that was numbered Rt. 112 for a short time in the mid-1920s.
No connection with post-1927 NM-112
Previously --- El Vado (1930s)
North terminus: U.S. 84 at Los Ojos
Length: 44.755 mi.
County: Rio Arriba

Improvements: Paved road
Comments:
East terminus: Rt. 58 at Pasamonte
1927 designation: NM-62
Present-day roads along this route: NM-120
This was a direct extension of Rt. 62 that was numbered Rt. 114 for a short time in the mid-1920s.
No connection with post-1927 NM-114
North terminus: U.S. 60 at Magdalena
Length: 3 mi.
County: Socorro
History: Established early 1950s, remained in state highway system until 1970s.
Improvements: Gravel road
Comments: Must've been something at Kelly to warrant a state highway. Maybe a big mine?
East terminus: Texas State Line (TX-114)
Length: 47.054 mi.
County: Roosevelt
History: Renumbered from NM-116 in the 1980s, which had in turn been renumbered from NM-92 in the 1950s. Both renumberings were in response to the corresponding Texas route being renumbered.
Improvements: Two-lane, paved
Comments: NM/TX-114 created a continuous route to Dallas.
East terminus: Rt. 8 at Española
1927 designation: NM-2
Present-day roads along this route: U.S. 84
Although Rt. 36 appears to have connected to Española, this designation appears to have replaced Rt. 36 for a few years in the 1920s.
No connection with post-1927 NM-115
East terminus: Rio Arriba County Rd. 455 at Canjilon
Length: 3.457 mi.
County: Rio Arriba
History: Created in the 1980s when part of NM-110 was removed from the state highway system.
Improvements: Paved
Comments:
North terminus: Colorado state line near Palmillo
1927 designation: NM-74
Present-day roads along this route: U.S. 285
This appears to have been the first state designation for this particular route, which became more important and ultimately became U.S. 285.
No connection with post-1927 NM-116
East terminus: Texas State Line (TX-116)
Length: 47 mi.
County: Roosevelt
History: Redesignated from NM-92 in the mid-1950s when the corresponding Texas route was renumbered TX-116. In the 1980s, it was again renumbered NM-114 when TX-116 was changed to TX-114.
Comments:
North terminus: BL I-25 (near I-25 exit 190)
Length: 15.792 mi.
County: Socorro, Valencia
History: An old piece of U.S. 85 that was restored to the state system in the 1980s. Not sure if it is part of the 1988 renumbering since U.S. 85 wasn't on this road at that time.
Improvements: Paved two lane
Comments:
Photo taken October 2005 at junction of NM-36
Previously --- U.S. 60 at Quemado (1940s-88); U.S. 60 at Pie Town (1930s-40s)
North terminus: NM-122 at Grants
Previously --- NM-36 S of Trechado (1930s-50s); U.S. 66/I-40 E of Grants (1950s-1988)
Length: 62.058 miles
County: Cibola
History: Originally established in the 1930s between U.S. 60 at Pie Town and NM-36 at Trechado (became NM-36, currently NM-603). Moved in 1940s to new route from Quemado to Trechado, extended in the early 1950s to U.S. 66 (current I-40) near Grants. Took over former NM-124 running parallel to I-40 west to Grants around 2000. On south, truncated to NM-36 at Trechado in 1988.
Improvements: Paved, two-lane road
Comments: Note that this took over former NM-124 from the I-40 interchange to Grants. Why the route shuffle took place, probably in conjunction with former BL I-40 through Grants being redesignated as NM-122, isn't clear.
East terminus: I-40 (exit 36)
Length: 36.852 mi.
County: McKinley
| History: Redesignated mid-1980s. |  |
Improvements: Two-lane, paved except divided section through Gallup
Comments: This road can be reached at the Arizona welcome center and rest area at Lupton by taking the north frontage road. Concurrent with BL I-40 through Gallup.
East terminus: U.S. 84 at Dilia
Length 5.647 mi.
County: Guadalupe
History: Established early 1950s. Unchanged since that time.
Improvements: Two-lane, paved
Comments:
East terminus: U.S. 56-412 E of Gladstone
Previously --- NM-39 at Roy (c. 1930-35); U.S. 64-87 at Grenville (1935-88)
Length 119.031 mi.
County: Harding, Union
History: Renumbered from NM-62 in 1932 when U.S. 62 was extended into the state. Extended northeast and north in the mid-1930s to Grenville. Segment north of U.S. 56 renumbered as NM-434 in 1988.
Improvements: Two-lane, paved except for gravel from Black Lake to Ocate.
Comments: This is the longest continuous state-numbered route. (Previously, it was NM-44 until that became U.S. 550, and before that it was NM-18 until the 1988 renumbering). If NM-9 is extended east of its current terminus, that road will take the honor.
North terminus: Colorado state line N of Shiprock
Motor trails: Navajo Trail, National Park to Park Hwy
1927 designation: U.S. 666
Present-day roads along this route: U.S. 491
Although this road north from Shiprock existed by the 1920s, and appears to have been a significant route, it did not receive a state route designation until probably 1925-26. This may be the highest pre-1927 numbered route.
No connection with post-1927 NM-121
North terminus: Chacon
Length 8.581 mi.
County: Mora
History: Established early 1950s.
Improvements: Paved, two lane
Comments:

Previously --- I-40 exit 79 at Milan (1980s-2000s)
Length 38.740 mi.
County: McKinley, Cibola
| History: Redesignated mid-1980s. Assumed part of the former BL I-40 around 2000 as far east as the east Grants exit. | |
Improvements: Two-lane, paved except divided section through Gallup
Comments: Note that this took over the former I-40 business route through Grants.
East terminus: U.S. 85 at Watrous
Length: ~30 mi.
County: Mora
History: Established c. 1930. Removed from state system by mid-1930s, then portion of route between Watrous and Fort Union restored as state highway in mid-1950s as NM-477. This segment is now part of NM-161.
Comment: The road between Ft. Union and La Cueva does not even show on maps any more. This designation does not appear to have been reused since the early 1930s.
Previously --- I-40 exit 79 at Milan (1980s-2000s)
East terminus: I-40 (exit 114) at Laguna Pueblo
Length: 25.523 mi.
County: Cibola
| History: Redesignated mid-1980s. | |
Improvements: Paved, two lane
Comments: Part of Route 66. Gave up part of its route to NM-117 around 2000, probably at the time that BL-40 through Grants became NM-122.
East terminus: Texas State Line (TX-125)
Length: 25.412 mi.
County: Lea, Roosevelt
History: Established mid-1950s as NM-294, renumbered in late 1950s as NM-125 presumably to match the renumbered adjoining Texas route.
Improvements: Two-lane, paved.
Comments:
