Location: South Western Slope
Length*: 23.43mi
S End: New Mexico border south of Redmesa, connecting with NM 170 (link to Steve Riner's site)
N End: Jct US 160 north of Hesperus

Counites: La Plata
Places: Redmesa, Kline, Fort Lewis, Hesperus

Annual Average Daily Traffic (2008):

  • 1900 at New Mexico border

  • 2000 at US 160

SH 140 is along the La Plata River the whole time, and from the border passes through Redmesa, Kline, Breen, Fort Lewis, and Hesperus.

SH 140 is an original 1920s highway, but it started out as a spur which went from US 160 south to Ft. Lewis, and that was paved by 1938. By 1939, it had been extended to Kline, and by 1954 it went from US 160 for 14mi to Marvel. By 1963 it was extended south to the New Mexico border, and was not paved only from Kline to the border. Entirely paved by 1965.

N End: Jct BL I-70/US 6 west of Clifton

Counties: Dolores, San Miguel, Montrose, Mesa
Places: Dove Creek, Slick Rock, Naturita, Uravan, Gateway, Whitewater, Clifton

Mountain Passes: North of Dove Creek, SH 141 goes over Gypsum Pass (6100ft). Not exactly a high pass, but it's still on maps.

Scenic & Historic Byways: Unaweep/Tabeguache (SH 145 to US 50)

  • 156.75: North jct US 50
  • 162.30: BL I-70/US 6 west of Clifton (end SH 141)

Annual Average Daily Traffic (2008):

  • 730 at US 491
  • 480 north of CR K8
  • 1500 west of SH 145
  • 2400 west of SH 97, Naturita

  • 1400 at US 50, Whitewater
  • 6700 north of US 50
  • 23,500 at BL 70/US 6, Clifton

This is one long highway. After starting at US 491, it goes north to Egnar, then turns and takes a very curvy route east to Slick Rock. Then, it goes up and over Gypsum Pass, and continues northeast, hitting SH 145 east of Naturita, and the confluence of the Naturita and Maverick Creeks. SH 141 then goes west through Naturita and Vancorum, then travels down the San Miguel River northwest to Uravan, and west of the there starts on a very curvy route northwest down the Dolores River canyon to Gateway. Then, it goes northeast up the West Creek, and winds its way over a ridge, picks up the East Creek, and goes northeast to US 50 at Whitewater. It goes northwest on US 50 for about 2 miles, then turns north toward I-70, but stops short of it at BL 70 between Grand Junction and Clifton. The section from BL I-70 to US 50 serves as the route for cut-through traffic going from I-70 to Montrose.

SH 141 is an original 1920s highway, but was shorter than now, going from Naturita to Whitewater only. By 1954 a significant portion in the middle had been turned back, so it went from Naturita northwest for 15mi, and from Whitewater southwest for 9mi. By 1956 those sections had been lengthened to 39mi and 24mi, respectively. Finally the gap was closed by 1957. By 1961 the only section not paved was around Gateway, which was paved by 1965.

SH 141 was extended southwest from Naturita to Dove Creek along what had previously been SH 80 in the purge of 1968, to eliminate number duplication with I-80S. The section from US 50 to Clifton was brought into the state system about 1970, but originally was numbered SH 146. Renumbered as an extension of SH 141 about 1986.


Location: San Luis Valley
Length*: 33.84mi
W End: Jct US 285 at Romeo
E End: Jct SH 159 at San Luis

Counites: Conejos, Costilla
Places: Romeo, Manassa, San Acacio, San Luis

Scenic & Historic Byways: Los Caminos Antiguos

Milepost Guide:

  • 0.00: US 285, Romeo (begin SH 142 in Conejos County)
  • 14.21: Enter Costilla County
  • 33.84: SH 159, San Luis

Annual Average Daily Traffic (2008):

  • 2100 at US 285, Romeo
  • 2300 at 9th St, Manassa
  • 860 east of CR V
  • 220 east of CR 54
  • 440 at SH 159, San Luis

SH 142 starts at US 285 on the west side of Romeo, then heads due east through Manassa (Main St.), and crosses over the Rio Grande River halfway between Romeo and San Luis. It continues east, but the weird part is that instead of going like that straight to SH 159, four miles west of it SH 142 abruptly turns north for two miles to San Acacio, then goes east, ending at San Luis.

SH 142 is originally from the 1920s, but at first it went from US 285 only as far east as SH 136 south of La Sauses. Paved from Romeo to Manassa by 1939. Extended east to San Luis in 1954, but did not have the jog north through San Acacio. In 1955 it was rerouted so it did jog north through San Acacio. Entirely paved by 1957.


Location: Eastern Mountains

Originally from the 1920s, SH 143 went from SH 96 east of Silver Cliff north to Caņon City, then was projected/unimproved north to Victor. It started again in Cripple Creek and went northwest to US 24 at Florissant. By 1939 the projected portion was eliminated. Gone in its entirety by 1954.


Location: North Eastern Plains
Length*: 28.79mi
W End: South frontage road at I-76 grade separation & CR 1 west of Wiggins (halfway between Exits 60 and 64)
E End: Jct SH 52 at Riverview Ave./Main St. in Fort Morgan

Counties: Morgan

Annual Average Daily Traffic (2008):

  • 160 at I-76 frontage road
  • 330 north of US 34
  • 630 east of SH 39, Goodrich
  • 1500 east of CR 12
  • 2900 northwest of I-76, Log Lane Village
  • 4500 at SH 52, Fort Morgan

SH 144 has a mysterious beginning at an I-76 underpass halfway between Exits 60 and 64. To get to it you have to exit I-76 at one of those interchanges then use the north frontage road. From there SH 144 heads due north, across US 34, northeast over the South Platte River, through Orchard, northeast through Goodrich, then southeast to Weldona, across the South Platte again, then southeast, via Log Lane Village toward Fort Morgan. It has an interchange with I-76 at Exit 79, then heads east on Riverview Ave., ending at SH 52 north of downtown. SH 144 is next to or near the South Platte River for most of its length, meandering in and out of cottonwood groves.

SH 144 dates from the 1920s, but used to be slightly different. In the west it at first only got as far south as US 34. By 1936 its east end had been moved from SH 52 to US 6-34 due south of Weldona via CR 12. By 1957 the east end was moved back to SH 52, and SH 144 was entirely paved by 1961. SH 144 was extended from US 34 over a gravel road to I-76 about 1974, and was paved by 1977.

SH 144 suffered severe damage from South Platte flooding west of Goodrich, due to heavy rain upstream Sept 11-15, 2013. SH 144 underwent emergency repairs and was reopened in early November 2013.

SH 145 starts at US 160 on the east side of Cortez, then heads north to Dolores, then follows the Dolores River northeast up toward Lizard Head Pass. Along the way, it goes through Stoner and Rico. From Lizard Head Pass, SH 145 goes north past Ophir then through Mountain Village. North of Mountain Village is the junction (which the USGS calls Society Turn) where you turn east to go to Telluride. SH 145 goes northwest from there along the San Miguel River northwest through Sawpit and Placerville. It breaks out of the canyon, and heads west to Norwood. Then, it stairsteps northwest to Redvale, and goes northwest ending at SH 141.

SH 145 is an original 1920s highway, going from US 450/SH 10 at Dolores northeast to Rico, then through Placerville and Norwood, ending at Naturita. SH 10 was rerouted in the Cortez area by 1938 so SH 145 was extended south from Dolores to Cortez. By 1947 the first two sections were paved, from Cortez to Dolores and from Placerville to Norwood. By 1954 a section from Rico to Telluride Junction had been turned back, but that was brought back into the state system the next year. Also by 1954 what had previously been SH 108 from SH 145 east into Telluride was renumbered as a Spur SH 145. By 1964 the only section not paved was around Rico, and that was paved by 1970. The spur was turned back between 1994 and 1997.


Location: South Western Slope
Length: ~1mi
S End: Mesa Verde National Park
N End: Jct US 160 east of Cortez

This is an original 1920s state highway, and was the number for the road from US 160 south into Mesa Verde National Park. Turned back about 1938.


Location: South Western Slope
Alignment: Spur which went west for 5mi from US 666 (current US 491) south of Cortez


Location: Western Slope
Length*: 5.32mi
S End: 1970-1971: Jct SH 340 east of Grand Junction; 1972-1986: Jct US 50 northwest of Whitewater
N End: Jct BL I-70/US 6 west of Clifton

SH 146 is the original number for current SH 141 from US 50 up toward I-70. That routing, however, didn't become a state highway until about 1970, and at first didn't reach US 50, only getting as far south as an old part of SH 340. It was extended south to US 50 by 1972. SH 146 was renumbered as an extension of SH 141 in 1986. Probably changed for route continuity, although I wouldn't see it as necessary.


Location: South Western Slope

SH 147 dates from the 1920s, and at first went from SH 145 at Dolores north to SH 145 near Norwood via McPhee Park and Cone Reservoir. By 1938 it was extended from Dolores west to US 160 at Lewis. By 1946 the first section was paved from Lewis to Dolores. By 1954 the section north of Dolores was gone, so SH 147 went the *8.13mi from Lewis to Dolores only. By 1977 it was extended southeast ~6mi toward Summit Reservoir. All of it was renumbered as part of SH 184 in 1978.


Location: Eastern Plains
Length: 10mi
W End: Jct SH 51 north of Holyoke
E End: Jct SH 176 at the Nebraska border

Original 1920s highway. Deleted by 1954. Was a link which went from SH 51 (current US 385) due east to the point where current SH 23 (then SH 176) hit the Nebraska border.

  • 370 north of Browns Lake Rd
  • 2100 at 3rd St, Lake City
  • 520 north of CR 13
  • 690 at US 50

After starting at South Fork, SH 149 heads northwest up the Rio Grande River. Peaking out the Strange Town Name Meter is a town passed through named Wagon Wheel Gap. Then, it's northwest to Creede along the Willow Creek, and there SH 149 takes two 90 degree turns and heads back southeast along the other side of Willow Creek. That doesn't last long, though, and SH 149 picks up the Rio Grande again going southwest, then northwest. It uses a very curvy route going over the passes mentioned above, then goes into Lake City. It follows Gunnison St. through town, then picks up the Lake Fork of the Gunnison River heading north. At Gateview, it turns off that and heads east to Powderhorn, then turns north and ends at US 50 at the east end of Blue Mesa Reservoir.

SH 149 is an original 1920s state highway. By 1954 the middle portion of it between Creede and Lake City had been turned back, and was paved from South Fork to Wagon Wheel Gap. By 1960 it was paved northwest to Creede. By 1963 the only portion not paved was around the north end at US 50. By 1964 SH 149 was extended southwest from Creede over gravel to the Spar City turnoff. In 1966 the highway's end at US 50 at Iola had to be realigned because of the construction of Blue Mesa Reservoir.

By 1970 SH 149 was extended from Lake City to Spring Creek Pass, and by 1974 had been extended from the Spar City turnoff southwest for ~6mi. By 1977 the only gap in SH 149 was near Santa Maria Lake, and every other segment had been paved. Gap was closed by 1984.


Location: San Luis Valley
W End: Jct SH 17 at Mosca
E End: 1920s-1953: Jct SH 69 at Gardner; 1960-1973: Great Sand Dunes National Monument

This SH 150 is an original 1920s highway, which started at SH 17 at Mosca, went due east to GSDNM, to Red Wing, then went to SH 69 at Gardner. It had a projected/unimproved section through the Sangre de Cristo Mountains over Mosca Pass. By 1954, SH 150 had been turned back in its entirety, and there was no state road which serviced GSDNM.

About 1960 SH 150 was brought back and went from Mosca east, ending at GSDNM. That was a gravel road which was paved by 1963. This SH 150 was turned back in 1973 and the current SH 150 (see below) implemented. Old 150 from Mosca to GSDNM is now CR 6N Lane.

  • 4200 at SH 172, Ignacio
  • 1400 east of CR 334
  • 900 northeast of Arboles
  • 770 at US 160

SH 151 starts at SH 172, and heads east out of Ignacio on Ute St. Then, it goes southeast to Allison, east to Arboles, and comes within about one and a half miles of the New Mexico border, but the Navajo Reservoir is now in the way (it didn't used to be). SH 151 then heads northeast up the Stollsteimer Creek, ending at US 160.

SH 151 is an original 1920s state highway. Went from US 160 south to Arboles, then south to New Mexico. By 1954, it ended at Arboles, but at the same time SH 172 came southeast and ended there, so they ended at each other. By 1963 SH 151 was paved from US 160 halfway to Arboles. It was extended northwest to Ignacio up what used to by SH 172 about 1972.


Location: San Luis Valley
Length: 1920s-1953: ~20mi; 1954-1982: *5.55mi
W End: Jct SH 159 in San Luis
E End: 1920s-1953: Jct SH 111 at Monument Park; 1954-1982: Chama

Original 1920s highway. Went from SH 159 at San Luis east to Chama, then was projected over the Sangre de Cristo Mtns. via Whiskey Pass to SH 111 (current SH 12) at Monument Park. By 1954, it had been relegated back as a spur which went from San Luis to east of Chama only. Paved by 1957. Turned back in its entirety about 1982. The San Luis to Chama section is now CR P.6.


Location: Southeast Metro Denver

SH 153 is an old metro Denver highway, generally along Colorado Blvd. Starting in 1936, it went from SH 177 at Yale/University east on Yale to Colorado, then north to SH 83 at Leetsdale. By 1939 it used Quincy to go from Santa Fe Drive (US 85) east to Colorado, then north to Leetsdale. By 1954 the Valley Highway (SH 185/US 87) was being built, and SH 153 went from that north to Colfax (US 40/SH 2). By 1960 it was extended south from the Valley to Hampden (SH 70). Renumbered as an extension of SH 2 in the purge of 1968.

If you ask me, what they should have done instead in 1968 was renumber Colorado north of Colfax as an extension of SH 153, but keep SH 2 from US 6-85 through Commerce City up to I-76.


Location: North Eastern Plains
W End: Jct US 38 (later US 6) east of Sterling
E End: 1929-1936: Holyoke; 1936-1954: Jct SH 59 south of Haxtun

SH 154 was created in 1929 after the routing of SH 14/US 38 east of Sterling was changed. Orignally the road northeast from Sterling through the sand hills to Fleming didn't exist, so SH 14/US 38 went east from Sterling on either modern CR 22 or CR 24, then north on either CR 67 or 71, and east to Fleming. SH 14/US 38 had its route northeast from Sterling built by 1929 (modern US 6), so SH 154 was created along its former route (including the modern east-west section of SH 61) from east of Sterling, east along CR 22, and east all the way to Holyoke. By 1936 SH 154 had its east end trimmed back to SH 59 south of Haxtun. In 1954, SH 154 was eliminated, and the section west of SH 61 was made an extension of that highway.


Location: North Eastern Plains
Length: 31mi
SE End: Jct SH 14 northwest of Buckingham
NW End: Wyoming border north of Hereford, maybe connecting with WY 214?? (link to Andy Field's site)
Places: Keota, Grover, Hereford

SH 155 is an original 1920s highway, which went from SH 14 west of Buckingham northwest via CR 390 through Grover to the Wyoming line. Almost all maps show this county road nowadays. Turned back by 1954. In its heyday, it might have connected with WY 214.


Location: San Luis Valley
Length: ~20mi
SW End: Jct US 450 east of Alamosa
NE End: Jct SH 150 near Great Sand Dunes National Monument

Original 1920s highway in the area north of Alamosa. It went from US 450 (current US 160) east of Alamosa northeast to SH 150. Deleted by 1939.


Location: San Luis Valley
Alignment: Spur from SH 17 at Mosca due west to the Rio Grande/Alamosa County line


Location: Eastern Plains
Places: Falcon, Elbert, Kiowa

SH 157 is an original 1920s highway. At first it started at SH 85 then went east to Falcon then northeast through Elbert to Kiowa. By 1936 the section west of Falcon was eliminated, so it went only from US 24 to SH 86. By 1936 a spur was added which took it another 7mi north from Kiowa. By 1954 most of it had been turned back, and was only a spur which went north from Falcon for 4mi. Gone entirely by 1955.

SH 157 starts at a somewhat odd interchange with US 36. It's a pretty complicated interchange, with Foothills Pkwy, the Boulder Turnpike, Table Mesa Dr. ("Table Table" Dr. with the translation), and South Boulder Road all getting a piece of the action. What matters is that one can get from southbound 157 to southeastbound 36 (and the reverse movement) with no stopping. From there, Foothills goes north, and is a divided expressway with a speed limit of 45mph. They actually got the "parkway" part right, because the median is landscaped, and there is very little access.

The first access point is a signal light at Baseline Road, a mile north of US 36. Next thing north is Colorado Ave., then a massive intersection at Arapahoe Ave. (SH 7). North of that, SH 157 climbs up an artificial incline, and goes over Pearl St., where there is a diamond interchange. Next access point is at Valmont Road, with a signal light. North of that, SH 157 has an interchange with SH 119, where it ends. See my SH 119 listing for more on the 119-157 interchange.

CDH started having plans for Foothills Parkway in the early 1970s. In the 1971 route log it is listed, but all of it is "projected" since it hadn't been built yet. Also, apparently CDH at first envisioned it as longer, continuing southwest from its current end, because the 1971 log lists its south end as SH 93 south of Boulder, but that plan was scrapped by 1976.

Foothills Parkway was built in stages coming north from US 36. The first segment was from US 36 north to Baseline Rd., completed by 1975. Next was north to SH 7 (Arapahoe Ave.) by 1980. Then it was north to Pearl St. by 1984, to Valmont Rd. by 1988, and finally completed to SH 119 by 1989.
