Numbers derived from previous route numberings

[MNHighwayMan]

Somebody mentioned MN 62 previously, as it was previously CR 62. What wasn't mentioned was that it was (probably) numbered CR 62 in the first place because it lines up with 62nd Street in Minneapolis's street grid.

ROAD-CEPTION!!!!   

Petition to create I-62 now in the works.

I love and hate everything about this proposal.

I-290 in Chicago is the former route of I-90. I was 8 when they rerouted I-90 from the Ike to the Kennedy, so I'm old enough to have ridden on its original route.

BC-99 derives its number from US-99 which no longer exists (and WA-99 makes it nowhere near the border either).

Arizona 80 is the former route of US 80 south and east of Benson.  It continues east as New Mexico 80, which is also the former route of US 80.

When US 89 was truncated at Flagstaff, the routes south of I-40 that used to be US 89 and Alternate US 89 became Arizona 89 and 89A, respectively.

There are two spur routes off of I-19 north of Nogales that are Arizona 189 (which leads to the alternate International Border crossing) and 289, even though there is no longer any kind of route 89 anywhere near them.

Literally any state or county route named after US 66 or 99, etc.

[US 89]

Oklahoma's SH 325 was numbered because it originally connected to NM 325, which has since been rerouted and replaced by NM 456.

Sorry for the late comment, but I just got around to reading this thread.

In Indiana, along the new US-24 expressway/Hoosier Heartland Highway, former routings of US-24 which still service towns or have plenty of traffic are designated x24.  I believe the same is true along US-31.

The only state highways currently numbered x24 are 124 and 524, and while both derive their numbering from US 24, I can't find any previous routing of US 24 that follows those routes.  Former routings through Wabash and Peru are designated as Bus US 24 (though poorly signed) and former routings through Fort Wayne, Huntington and Logansport are not designated as anything.

Former routings of US 30 and US 31 do have 900 series state routes along former routings in Fort Wayne, South Bend and Kokomo.

Add US 33 to the list of old US routings that got renumbered as SR-9xx. When US 33 was truncated at US 20 on Elkhart's south side, the portion in St. Joseph County became 933. I still wonder what was wrong with 33 running all the way to Benton Harbor, MI.

Once the US 20 bypass was completed around Mishawaka/Elkhart, INDOT no longer wanted to maintain the previous routing of US 33.  That would have forced US 33 to be concurrent with US 20 and then US 31 from Dunlap to Benton Harbor, and thus it was truncated to Dunlap. 

Elkhart city and county took over their parts of the old routing, but St. Joseph County, Mishawaka and South Bend cities refused, so thus we have 933.

Yeah, I realized why INDOT chose to truncate 33 at Dunlap, I just disagree with that decision. Like many such cases, INDOT makes perfectly good routes discontinuous to avoid maintaining them.

I rather like that INDOT is focusing their resources on actual highways rather than Main Street and Franklin Street in Elkhart.  I do wish there were a way to keep highway designations on these streets even though they are under local control, but I don't know how well that would work.

Anyone mention NB-95 yet? (comes from the fact that it continues from I-95)

Ditto Manitoba 29, 59, 75, and 83.

MB-89, not 83; also 310. I also thought MB-29 was eliminated, since the US-75/MB-75 border crossing was closed and 75 was re-routed to meet I-29 at the border.

You're correct on MB 29; when it did exist it (for over 40 years, apparently) was a continuation of I-29.

MB 83 is a continuation of US 83

It also appears MB 32 is a continuation of ND 32.

I'm pretty sure the OP is looking for decommissioned or truncated routes, not the other sense of "previous route numberings".

Oops, I was just thinking of the ones in Minnesota, forgetting that there are going to be some in North Dakota too.
