West terminus: U.S. 550 at Cuba
East terminus
: NM-4 at La Cueva

Length: 39.654 mi.

County: Sandoval

History: Established in the mid-1930s.

Improvements: Two lane paved, with gravel section on about half the route through the national forest..

Comments: My Benchmark Atlas showed this route turned back to the National Forest Service inside the national forest, but the 2003 state highway map and the current milepost map show it in its original entirety.

Original NM-127 South terminus: Salt Lake
North terminus
: U.S. 60 at Quemado

Length: 25 mi.

County: Catron

History: Established late 1930s. By the 1940s was part of NM-32, and is now part of NM-601.



West terminus: Idyllwild
East terminus
: U.S. 64 at Eagle Nest

Length: 3.53 mi.

County: Colfax

History: May be a relatively recent route (mid 1980s). A post-1988 route would have a 4xx designation. Not shown on any oil company maps.

Improvements: Two-lane paved highway


NM-128 West terminus: NM-31 E of Loving
East terminus:
Texas State Line (TX-128) E of Jal

Length 59.979 miles

County: Eddy, Lea

History: Established late 1950s. Incorporated NM-256 E of Jal, which had been established early 1950s.

Improvements: Two-lane paved


Highway Engineering 101: don't route a roadway through a swale if you can avoid it. Just east of NM-31, NM-128 runs along the north side of Salt Lake. Work is underway (as of the time the photo was taken) to relocate the road to higher ground to the north.

South terminus: I-40 (exit 300) at Newkirk
Previously --- NM-67 at Isidore (c. 1935-37)
North terminus: NM-104 S of Conchas Dam
Previously --- Conchas Dam (mid-1930s-1988)

Length: 17.383 miles

County: Guadalupe, San Miguel

History: Established in the 1930s, originally beginning at NM-67. When that route was truncated in the mid-1930s, NM-129 assumed the former route of NM-67 south to U.S. 66. On the north, the route ran to Conchas Dam, and even after NM-104 was extended to Tucumcari, these routes had a concurrent section south of the dam. NM-129 was truncated at the south junction with NM-104 in 1988.

Improvements: Two lane, paved



Photo taken near U.S. 82 junction at Cloudcroft

West terminus: U.S. 82 at Cloudcroft
Previously --- NM-24 N of Weed (1950s-88)
East terminus: U.S. 82 at Mayhill

Length: 21.872 mi.

County: Otero

History: Established mid 1950s from NM-24 to NM-83 (now U.S. 82). Assumed the former route of NM-24 west to Cloudcroft in 1988.

Improvements: Two lane, paved



West terminus: Manzano Mountains State Park
East terminus
: NM-55 at Manzano

Length: 2.401 mi.

County: Torrance

History: From its number, must have been established before 1988 (otherwise it would be a 3xx route). However, it does not show on any maps prior to the 2003 New Mexico official highway map, including the 1999 Benchmark Atlas.

Improvements: Two lane, paved


    NM-132 South terminus: NM-18 at Hobbs
North (bends east at its north end) terminus
Texas State Line (TX-83) E of Lovington
Previously --- NM-83 W of Texas State Line (1930s-88)

Length: 19.76 mi.

County: Lea

History: Established mid-1930s. Assumed the easternmost part of NM-83 in 1988, east to the Texas border.

Improvements: 2-lane, paved road

Comments: The number change at the east end of NM-83 is a bit illogical, even though 83 is a side road at this junction (the road bends 90° east a couple of miles north of the junction). Despite this jog to the north, 83 used to form a continuous route from Lovington to Denver City, TX.

NM-133 West terminus: NM-132
Previously --- NM-83 E of Lovington (1940s-80s)
East terminus:
Texas State Line (Texas FM-1757)

Length: 3.6 mi.

County: Lea

History: Established mid-1930s, probably the same time as 132. Extended west and north to NM-83 in the 1940s. This latter segment was removed from the state highway system by 1988.

Improvements: Two-lane, paved


Original NM-134 South terminus: U.S. 70 at Las Cruces
North terminus
: U.S. 85 at Ft. Selden

Length: 18 mi.

County: Doņa Ana

History: In the late 1930s, U.S. 85 north of Las Cruces was moved onto a more westerly alignment, and old U.S. 85 was given this designation. By the early 1940s, this was renumbered as an extension of NM-28. It is now a county road.



West terminus: Navajo Route 12 near McKinley-San Juan County Line
East terminus
: U.S. 491 at Sheep Springs

Length: 22.47 mi.

County: San Juan

History: Established 1980s

Improvements: Existing portion of the state route is paved.



West terminus: U.S. 66 W of downtown Albuquerque
East terminus
: U.S. 85 S of downtown Albuquerque

Length: 4 mi.

County: Bernalillo

History: Established early 1950s. Removed from state highway system by late 1960s.

Improvements: Existing portion of the state route is paved.

Comments: Ran along Bridge Blvd. from just west of the Barelas Bridge, where U.S. 85 turned south onto Isleta Blvd., to Central Avenue. Although late 1960s and early 1970s maps show this route as removed, I remember references to it from when I lived in Albuquerque in the mid-1970s. Whether on maps or actual posted signs I don't remember.

Original NM-136 South terminus: NM-17
North terminus: Colorado State Line

Length: ~7 mi.

County: Rio Arriba

History: Established early-mid 1930s as a replacement for the original route (NM-106) connecting New Mexico and Colorado northwest of Chama, prior to extension of U.S. 84. This road became U.S. 84 in the early 1940s.



This sign with the faded zia taken just west of the Texas-New Mexico state line west of I-10. East of here it is TX-178.

South terminus: Mexico Border W of El Paso
North/east terminus
Texas State Line (TX-178) at El Paso

Length: 8.8 mi.

National Highway System Route

County: Doņa Ana

History: Constructed in the 1990s as a connection to a new Port of Entry on the Mexican border at Santa Theresa.

Improvements: Two-lane and divided highway

Comments: The NHS map also shows a designated future route from this road, where it bends from north to east, to intersect I-10 north of Anthony. Also named Pete V. Domenici International Highway for the Senator. It currently connects with Artcraft Road (TX-178), which intersects I-10 north of El Paso.

NM-137 West terminus: Texas State Line at Dog Canyon (Guadalupe Mountains National Park)
Previously --- Probably El Paso Gap, but earlier maps are ambiguous and inconsistent
East terminus: U.S. 285 N of Carlsbad

Length: 55.007 mi.

County: Eddy

History: Established late 1940s. May have originally terminated at one of the road forks as the road heads west and south in to the mountains, but since maps are ambiguous it is possible it was always a state highway as far as El Paso Gap. It was extended south to the Texas border, probably 1990s.

Improvements: Two-lane paved road


NM-138 West terminus: NM-478 S of Mesilla Park
East terminus: Stern Drive (I-10 S. Frontage Road, FR 1035)

Length: 0.67 mi.

County: Doņa Ana

History: Probably established late 1990s or early 2000s.

Improvements: Two-lane paved road

Comments: Follows Main St. through Tortugas, goes under I-10, curves north along Espina Street to the frontage road. Formerly considered part of NM-342 spur.


No history of a state route with this number found.


West terminus: NM-185 E of Hatch
Previously --- NM-26 at Hatch (pre-1988)
East terminus:
I-25 at Rincon (exit 35)
Previously --- Rincon. Possible extension back to U.S. 85 in the 1960s before construction of I-25.

Length: 2.828 mi.

County: Doņa Ana

History: Established c. 1950, may have gone back to U.S. 85 at some point. In 1988, the connection from Rincon to Hatch became NM-154, and this route number was applied to the road from Rincon south to NM-185.

Improvements: Two-lane, paved


NM-141 West terminus: NM-11 S of Deming
East terminus
: (NM-497 or 198) and NM-141 near Rock Hound State Park

Length: 7 mi.

County: Luna

History: Not sure of the history of this route, possibly created c. 1988. Removed from state highway system by 2003, now Luna County B026.

Improvements: Paved two lane

Comments: Ended at an intersection where each leg had a different route number. The two other legs were consolidated into NM-143, the only surviving route to Rockhound State Park.


South terminus: NM-52 near Cuchillo
North terminus
: S of Placitas
Previously --- NM-52 at Ojo Caliente (1930s-1980s)

Length: 10.088 mi.

County: Sierra

History: Created in the late 1930s. Shortened probably in the 1980s.

Improvements: Paved



Photo taken at junction with Luna County B026 (former NM-141).

South terminus: Rock Hound State Park
Previously --- NM-497 and NM-141
North terminus: NM-549 E of Deming

Length: 6.147 mi.

County: Luna

History: Created 1988 as part of a highway transfer agreement with Luna County. Apparently ended at a three-way terminus with NM-141 and NM-497. When 141 was removed from state system after 2000, this route and 497 were merged into a single route.

Improvements: Paved two lane



West terminus: Camp Luna Technical-Vocational Institute
East terminus
: NM-65 NW of Las Vegas

Length: 1.23 mi.

County: San Miguel

History: Would probably pre-date 1988, since new routes in this area would be NM-5xx.

Comments: Only exists to serve the school.

NM-145 West terminus: NM-184 near Black Springs
East terminus
: NM-52

Length: ~25 mi.

County: Catron

History: Created in the mid 1930s. Shortly thereafter, combined with other routes to form the extension of NM-78 which existed until 1988. Now called NM-163.

Comments: One of several routes in the northern part of the Black Range that were created in the 1930s and then redesignated within a few years. Only shows on a 1936 map.

NM-145 West terminus: NM-80 S of Road Forks
East terminus: NM-338 N of Cotton City

Length: 3.5 mi.

County: Hidalgo

History: Designated c, 1988.

Improvements: Two-lane, paved


NM-146 South terminus: NM-9 at Hachita
North terminus
I-10 (exit 49) W of Wilna

Length 19.157 mi.

County: Luna

History: Established 1940s as part of NM-81. This segment, due to short concurrency with NM-9, was redesignated as NM-146 in 1988.

Improvements: Two-lane, paved


NM-147 West terminus: NM-314 at Isleta Pueblo
East terminus
: NM-47 at Isleta Pueblo

Length 1.07 mi.

County: Bernalillo

History: Established 1980s (?) as link between old U.S. 85 and NM-47 at Isleta Pueblo.

Improvements: Two-lane, paved

Comments: Coincidence, or is this a rare instance (for New Mexico) of a three-digit state route number based on one of its intersecting routes (47 --> 147)?

NM-148 West terminus: NM-331 S of Deming
East terminus
: NM-497 S of Deming

Length: ~2 mi.

County: Luna

History: Beginning and ending not known with certainty, and its existence is only indicated by its being shown on on-line maps. From its number, it probably would have been established in 1988. Most likely removed after a few years.

Comments: This would have followed Solana Road west of NM-497, which presently or formerly came south from Deming parallel to and west of NM-11 before turning east on Solana Road. It may currently be Luna County Road C-57. This route is shown ambiguously on Mapquest along the same route as the indicated county designation. NM-331, its western terminus, I believe has been removed from the state highway system.


No history of a state route with this number found.
NM-150 South terminus: NM-522/U.S. 64 N of Taos
North terminus
: Taos Ski Valley

Length 14.547 mi.

County: Taos

History: Established c. 1960, may have been T route with one leg going to NM-3 (present-day NM-522) at Arroyo Hondo. Appears to have been routed onto a new road that intersects 522 and U.S. 64 at their junction.

Improvements: Two-lane, paved

Comments: Passes through the artist colony of Arroyo Seco. North of there, after the north junction with NM-230, runs up the Rio Hondo canyon to the Taos Ski Valley.
