US Highways that Should Be (or Should Have Been): A.K.A. : My wild idea bin. I am not adding any more reader submitted new routes to this list. If you have ideas you want to share, post them to misc.transport.road, or even make a page on your website for them. I'll link to it.
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,

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. (Thanks to David Sturm for the original
idea) 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.) Another possible idea would be to replace Alt US 41
from Hopkinsville, KY to Monteagle, TN.

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. It has been signed in Montana, apparently. 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 I chose
this route was 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
through Douglas 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,

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, there
is even an END US 99 already posted there). (RVD)
US 100 is
implied by the 1925-1926 numbering scheme. My plan for '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 my favored alignment (per 1998 RMcN):
From Miami, FL along US 41 to Bradenton, FL. Then it would cross

US 402 is
often kicked about as a potential highway number. MSR 200 is
often mentioned as a potential candiate for this route, to the
point of assigning US 200 along it. I prefer US 402 because it
fits in the existing grid. On his website, Steve Riner suggests a
different US 402. His route would run from just east of Sioux
Falls, SD to just south of Sault Ste. Marie, MI. 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?
If you
have posted an idea for the routing of a new, improved, or
extended US highway or Highways on a web site, or even another
renumbering, E-mail me and I will add your site to the links
below.
Andrew Field has a proposal for US 789
Drop me a line if you can think of any more.
US highways existed for about a year, many only in the planning stage. State highway agencies have sometimes reported these as posted. There was serious talk of a series of cross country tollways in the 1940's - using the noertheastern and midwestern toll roads as a model. These could have used the unused-at-thtat-time US n00 series : even first number for the four east-west mainlines, and odd numbers for the north-south mainlines. US 100 = I-95, US 200 = I-90, US 300 = I-75, US 400 = I-80, US 500 = I-55, US 600 = I-40, US 700 = I-25, US 800 = I-10, US 900 = I-5. Other corridors would remain free and upgrade as funds became available. Some numbers have appeared as map companies jumped the gun and made maps 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 (numbers from that proposal still not re-used listed below). All routes listed below are considered historic (apocryphal), but were not labeled in(this) manner for clarity.

The 1959 Texaco 49 State Road Atlas included a small map of Hawaii, pre-statehood. It appeared to show a network of US numbered nighways.Oscar Voss's Hawaii Highways explains about these territorial routes. They did exist during World War II and used US-style shielding. Hawaii was not happy about this old map resurfacing. The newly minted state had its own roads to promote and next year got an updated entry.
Washington, D.C. used a US style shield from the mid-1930's
to the mid-1950's for extensions of Maryland state highways 4 and
5 within its borders. A full size photograph of the
thumbnail on the right is in Library of Congress
archives at
http://memory.loc.gov/pnp/fsa/8b14000/8b14400/8b14423r.jpg.
There is a 1942 Esso map of these routes at http://memory.loc.gov/cgi-bin/query/D?gmd:1:./temp/~ammem_VuzL::@@@mdb=gmd,
ending south of the White House at 17th St (US 1).
I have access to a 1950 Bureau of Public Roads highway map that suggests there may have been other US Territorial Highways, but it gives no routing or numbering information.
US Highways that Could Have Been
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.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 areitalicized. Matthew Salek researched these and other multi-state state routes in a site maintained by J.P. Kirby.

| MSR 120 | Toledo, OH | OH MI IN | Elkhart, IN | OH-120 MI-120 IN-120 | US 120? Michigan segment now a County Road. |
| MSR 121 | Rock Hill, SC | SC GA FL | Lebanon Sta., FL | SC-121 GA-121 FL-121 | US 121? Commissioned 1961; One of the very few numbers Florida carries over from another state that is not a US or I-route. A new US 121 has been proposed, maybe US 621 could cgo on this route. |
| MSR 200 | (Duluth, MN) Jacobson, MN |
MN ND MT IDWA | Sandpoint, ID (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 now. I like the idea of just making it Alt US 2. |

There would be too many parts of the route concurrent with other numbers for most of the DOT's involved. First proposed 1941 by Colorado. Has existed since 1954, S exten to CO in 1955, NM and AZ in 1956. Most states dropped the number in the 1980's, leaving Wyoming with an oddly numbered highway. |
Definitions of the abbreviations used as well as some of the more obscure termini can be found here.
