US Highways that never were, US Highways that should be (US 47), US Highways that almost were (US 60N), and US Highways that could have been, and might still be (proposed US 121).

* US 560 was proposed in BPR 1925 for what became US 666 but never actually utilized on any US highway.

US Highways that Should Be (or Should Have Been) : AKA : My Wild Idea Bin.

US 0 is implied by the 1925-1926 numbering scheme. US 2 occupies where a major "0" digit route might have gone, but AASHO and BPR of the day decided against 0 as a route number. If it had actually used, it would have most likely gone from Sault St Marie, MI to Bonners Ferry, ID over the west section of US 2. What I would like to see would be 'The Canadian Route'. It would have run along the Canadian border, starting at Calais, ME. and ending at Blaine, WA. It would have followed US 1 to ME 6, then ME 16 to NH 16, NH 26, then US 3, VT 114, VT 111, VT 105, VT 78, onto US 2, US 11, NY 122, NY 37, NY 12, NY 12E, NY 3, NY 104, NY 18, I-190, NY 5, then PA 5, US 20 to OH 2, up I-75, I-94, MI 25, MI 13, US 23, I-75, MI 28, US 2, over to MN 61, MN 1, US 53, US 71, MN 11, US 59, MN 175, to ND 5, then MT 5, MT 13, US 2, MT 40, US 93, MT 37, again on US 2, WA 20, ending up on I-5. This route won't be signed because there is no need for a new transcontinental highway along this corridor. I don't think there are any Route Zeroes in existance, currently, anywhere. (RVD)

US A1A could be an extension of a numbering quirk in Florida. When FL 1 was reassigned in 1946, the new grid routing for it paralleled the existing US 1. It was rechristened FL A1A in 1947 to alleivate confusion and to pretend to be a US 1 Alternate route. (Highway enthusiasts, also known as "road geeks" refer to it as Atlantic 1 Alternate, even though there is no evidence that was the intent.) There is no single highway number stretching along the Atlantic coast as US 101 does along the Pacific coast. US 1, US 9, US 13, and US 17 come close at times to being a true Atlantic Coast Highway. A US A1A would start at Calais, ME, possibly connecting to a Canadian A1A. It would end in Key West, supplanting FL A1A on Roosevelt Blvd. It would cross the states of ME, NH, MA, CT, NY, NJ, DE, MD, VA, NC, SC, GA, FL. Routes along its alignment: US 1, ME 189, ME 191, US 1, ME 187, US 1, Alt US 1, US 1, ME 186, US 1, ME 172, ME 175, US 1, ME 9, US 1, NH 1A, MA 110, US 1, MA 1A, MA 133, MA 128, MA 127, MA 127A, MA 127, MA 1A, US 1, MA 3A, MA 3, MA 6A, MA 28, MA 28A, MA 28, US 6, MA 177, RI 177, RI 81, RI 179, RI 77, RI 24, RI 138, RI 138A, RI 138, RI 1A, US 1, RI 1A, US 1, Alt US 1, US 1, CT 251, US 1, Ferry, NY 25, Ferry, NY 114, Ferry, NY 114, NY 27, NY 27A, NY 27, I-278, Hylan Blvd, NY 440, NJ 440, NJ 35, NJ 36, NJ 71, NJ 35, NJ 37, US 9, Ferry, US 9, DE 1, MD 528, US 50, MD 611, MD 376, US 113, US 13, US 60, VA 149, VA 165, VA 168, NC 168, US 158, Bus US 158, US 264, NC 99, NC 92, Ferry, NC 306, Ferry, NC 33, NC 304, NC 306, Ferry, NC 306, NC 101, US 70, NC 58, NC 24, NC 172, US 17, NC 133, NC 87, NC 211, US 17, Bus US 17, NC 179, US 17, Bus US 17, US 17, US 21, SC 170, US 17, GA 204, GA 144, US 17, GA 99, US 17, FL A1A, US 1, FL A1A, US 1, FL A1A. If they ever bridge over or tunnel under the Florida Straits to Cuba, this road could extend even further. (Original idea by David Sturm) It is doubtful the public would accept this odd highway numbering. A true single Atlantic Coastal Highway would be nice.

US 39 was left blank in all numbering plans I know of, and has never been in any published list or map as a proposed number for a US highway. One possible corridor would link Clarksville, TN to Florence, AL. It would be routed down TN 13, then down AL 17. It could possibly be extended to Deer Park, AL down the rest of AL 17. This possible extended route is straddled by US 45 and US 51 through Alabama, and has relatively little population. (Original idea RVD, modified by Dave Schul, who also suggested US 143 for this route.)

US 47 was left blank in all numbering plans I know of, and has never been in any published list or map as a proposed number for a US highway. One possible corridor would link Union City, TN to Yazoo City, MS. It would replace US 45W south to Fairview. It would multiplex with US 45 for two miles to Byp US 45 at Jackson, then multiplex agian for four miles. It would follow TN 18 across the border, then down MS 7 to Greenwood and replace US 49E to Yazoo City, MS where it would terminate. Current US 49E from Greenwood to Tutwiler could become part of MS 7. This route could even be extended up TN 21 and KY 239 & KY 123, then cross the Mississippi between KY 80 and MO 80 , then turn north at Whiting to terminate at Charleston, MO after a short trip up MO 102. One reason this route was chosen because it linked a pair of divided routes, a type which AASHTO is discouraging. (Original idea RVD, modified by Adam Froehlig, with other suggestions by Dave Schul.)

US 88 was left blank in all numbering plans I know of, and has never been in any published list or map as a proposed number for a US highway. This route would link El Paso, TX to Benson, AZ. It would begin at US 85, or even replace part of it into El Paso. It would cross the Rio Grande on current TX-273 / NM-273 then to Santa Theresa, then follow NM 9 to NM 80 near Rodeo, then AZ 80 to Benson. If it was extended further up the old US 80 alignment, it would multiplex with I-10 from there to Tuscon, where it would head north on AZ 77 to Catalina, then north on AZ 79 to end at Florence Junction. It would multiplex with US 60 from Florence Junction to Phoenix, then with I-10 to near Buckeye. The final leg would run down AZ-85 to Gila Bend at I-8. A more southern extension would multiplex with I-10 from there to Tuscon, then west on AZ 86 to Why, AZ. From there it could go north on AZ 85 to Buckeye, AZ or south on AZ 85 to Lukeville, AZ and Mexico. In the event of a possible US 93 extension to Lukeville, US 88 would be truncated at Why. (RVD, with suggestions by Alan Hamilton)

US 99 existed from 1926 to 1974 along what is now the I-5 corridor. Washington, Oregon, and California still have highways with the "99" number. This is a possible recommissioning. If adopted, this new 99 would provide an additional Canamex trade corridor along the west coast. A new US 99 would start at the Canadian border at Lynden, WA where Alt US 99 used to end. Former Alt US 99 would be followed south along current WA 539, then down another former Alt US 99 south of Bellingham, WA along WA 11. From Burlington, WA to Everett, WA, US 99 would have to be signed along I-5. From Everett southward, WA 99 is the obvious choice. Where WA 99 ends near Tacoma, WA the new US 99 would continue south on WA 7 till WA 507 breaks free from it south of Spanaway, WA. WA 507 would be followed south to Centralia, WA. US 99 would hop back on I-5 after that, and leave it at Toledo, WA. WA 411 would be followed south from there to Longview, WA, and across the existing bridge to Oregon. In Oregon, US 99 would follow US 30 south to west of Portland, then BYP US 30 up to OR 99W. OR 99W (Former US 99W) would become the new mainline US 99 southward, at Oregon's option OR 99E (old US 99E) would become Alt US 99. At Junction City, OR, US 99 would start to replace OR 99 southwards. At Eugene, OR, US 99 would rejoin I-5, following or paralleling it southwards to California, absorbing posted OR 99 into its alignment. US 99 would do much the same thing in California, absorbing former US 99 along its route to Red Bluff. From there southward, US 99 would start to follow CA 99, the former US 99E. At Bakersfield, CA, the new US 99 would leave CA 99, the remained of CA 99 would have to be re-numbered, possibly as CA 58. New US 99 would head eastward on CA 58 (former US 466) to Barstow, CA. From there, US 99 would go south on CA 247, then west around Joshua Tree National Monument on CA 62, cross I-10, then follow CA 111 (former US 99) to near Mecca, CA, south on CA 86 (former US 99) to Heber, CA, then it would finish its route south to Calexico, CA on the Mexican border on CA 111 (former US 99). (RVD)

US 100 is implied by the 1925-1926 numbering scheme. 'The Trans-Mexican Route' would have run along the Gulf of Mexico to the Mexican Border, starting at Miami, FL and ending at Chula Vista, CA. Routes along its alignment (per 1998 RMcN): US 41, US 19, US 98, US 90, LA 14, LA 27, LA 82, TX 87, TX 3005, TX 332, TX 36, TX 35, US 181, TX 44, US 77, US 281, US 83, US 277, US 90, I-10, TX 20, NM 9, NM 80, AZ 80, AZ 92, AZ 90, AZ 82, I-19, AZ 86, AZ 85, I-8, CA 98, I-8, CA 94, CA 188, CA 54. This route won't be signed because there is no need for a new transcontinental highway along this corridor. (RVD)

US 402 is often kicked about as a potential highway number. MSR 200 is often mentioned as a potential candiate. Steve Riner suggests a "Soo to Soo Highway." His route would run from just east of Sioux Falls, SD to just south of Sault Ste. Marie, MI (Thus the name). It would run on existing highways as follows: MN-23 from Beaver Creek, MN (Junction with I-90) northeast to I-35 just south of Hinckley. Brief duplex with I-35 north about five miles to the junction with MN-48. Past the Grand Casino and east into Wisconsin and WI-77. Across Wisconsin on WI-77 to Hurley and Junction U.S. 51. Business route through downtown Hurley and Ironwood, mainline marked on U.S. 51 and U.S. 2 east. East to Wakefield duplexed with U.S. 2, then replace M-28 east past Marquette to I-75. Most of the Minnesota and Michigan segments of this route are NHS designated. The Wisconsin segment is not NHS, but is a major connecting route.

What if there had been no Interstates?

  1. The system of Toll Roads that was starting to grow in the 1950's would have expanded. Some of those would have entered the US numbered highway system as TOLL US xx.
  2. Many of the midwestern and western roads that became four-lane limited access Interstates would still be two-lane highways today.
  3. More bannered routes, especially BY-PASS and CITY (B and C suffixes).
  4. Almost no truncations, and fewer decomissionings. US 66 and US 99 would still be active.
  5. Slower replacement of the train by trucks as the primary transcontinental freight haulers.
  6. Highway fatalities would have increased at a higher rate.
  7. More three digit US routes and some extensions of existing two-digit US routes.Many of the straighter geographic routes would have made it to the US system, especially in Utah and Arizona, possibly as limited access tollways.

If you have posted an idea for the routing of a new ,improved, or extended US highway on a web site, E-mail me and I will add your site to the links below.

Landry Heaton has ideas for possible routes US 0, US 39, US 47, US 88, US 100, US 389, US 789, and US 893.

Andrew Field has proposals for US 289, US 430, US 530, and US 789.

Adam Froehlig and Jeremy Lance have ideas for US 47, US 213, and some extensions of existing US highways

US Highways that Almost Were:

US highways existed for about a year, many only in the planning stage. State highway agencies have sometimes reported these as posted. Some map companies have 'jumped the gun', making a map from a proposal as opposed to the approved plan. The most famous example is the 1926 Rand McNally US Road Atlas, based on the preliminary report from BPR of 1925. Click here to see those 1925 routes. All routes are historic (retired), but were not labeled in (this) manner for space considerations.

US Highways that Could Have Been, and Might Yet Still Be.

Some of the numbers in this table have confused road enthusiasts at times, and some of these have even been referred to as US highways in some national publications. Also listed here are US highways recently propsed by State DOT's. NOTE: To keep this table managable, only the maximum termini have been shown if the highway was truncated, with the cities and states it is no longer in are italicized. Matthew Salek researched these and other multi-state state routes in a site now maintained by J.P. Kirby.

US 48 [III] Strasburg, VA VA WV Elkins, WV VA-55 WV-55 WV-93 WV-32 US-219 Proposed by WVDOT & VaDOT.
MSR 120 Toledo, OH OH MI IN Elkhart, IN OH-120 CR-120 IN-120 US 120? MI part now a CR.
MSR 121 Rock Hill, SC SC GA FL Lebanon Sta., FL SC-121 GA-121 FL-121 US 121? Extnd FL @1961; One of the very few numbers FL carries over from another state that is not a US or I-route.
US 121 [II] Beckley, WV WV VA Grundy, VA WV-16 WV-83 VA-83 Proposed by WVDOT & VaDOT, a US 419 would fit the numbering scheme better.
MSR 200 (Duluth, MN)
Jacobson, MN

(Spokane, WA)
MN-210 MN-200 ND-200 MT-200 ID-200 US-2 US 402?, maybe US 102 [II]?. US 200 is a possibility, there is a US 400.
MSR 789 (Sweetgrass, MT)
Frannie, WY

There would be too many parts of the route concurrent with other numbers for AzDOT. Has existed since 1954, exten S to CO in 1955, NM and AZ in 1956
