Then And Now: Same Intersection, Different Route Numbers

[thenetwork]

After doing a bit of research on some towns I was passing through on my work route, the town of Shiprock, NM had a dubious honor:

In 2020, US-64 and US-491 intersect just east of the San Juan River.  However, when I first passed through there on a family vacation in 1983, there were two different routes that met at that same intersection -- US 550 and US-666.

Today, US-666 had since been renumbered, while US-550 goes south to Albuquerque once it hits Broomfield about 45 miles east..

What other city intersections have completely different route numbers than in earlier days?

Outside Appleton WI, there was an at-grade intersection of US 10 and US 45.  Due to freeway construction and state highway extension and realignment, it is now the intersection of WI 76 and WI 96.

Are freeway interchanges included?

I know the MacArthur interchange started out as US-40, US-50, and US-101 E when the Bay Bridge opened but that is now known as I-880, I-80 and I-580.

Near Frankenmuth and Birch Run M-54 and M-83 come up to Birch Run Road in opposite directions on the same road then run together on Birch Run Road to end at I-75.

Pick any intersection that doesn't involve any National highway in Spain. 40 years ago, the roads had different numbers.

For example, this intersection was N-240 straight, HU-311 to the right and HU-530 (IIRC, not sure of its number) to the left in 1980. The latter became an extended C-125 in 1982. Since sometime in the 90s the three roads are numbered A-132, A-1206 and A-125 respectively.

Flint, I think you have the concept wrong.  The OP is asking where an intersection used to be Route A and B, and now it is Route X and Y because of route number changes.

M-45 and M-11 on the west side of Grand Rapids used to be US-16 and M-50.

And an almost-winner in Clinton MI (the town in Lenawee County, not the much larger Township in Macomb County).  It used to be the intersection of US-112 with M-92 and M-52.  Now it's the intersection of US-12 and only M-52.

Do we want to go back to before the advent of the US system?  There must be loads of changes related to that.  I can name several just in Michigan.  For example in Rapid River, it used to be M-12 and M-15, now it's US-2 and US-41. 

Not as many exist in the LP, since the location of the original M- routes replaced by US- routes have often been superseded by freeways.  I can think of the intersections of US-31 with US-131 in Petosky.  They used to be M-11 and M-13, respectively.

Toledo OH:  At the intersection of Monroe St. And Detroit Ave:

1985:  Monroe was US-223, Detroit was SR-25 (nee US-25).

1986:  Monroe became SR-51, Detroit became US-24.

Before US 33 and US 35 existed in Indiana, IN 33 and IN 35 existed and intersected at Mauckport.  They got renumbered to IN 11 and IN 135 respectively.

After re reading it I have to agree with ya. I was just by there the other night on Birch Run Road and thought well this is cool, one way is south M-54 and the other way is north M-83. I got the idea now though with your examples.

[Flint1979]

I think I might have an example in Saginaw.

Use to be US-10/M-47 and M-47
Then it was M-81 and M-84
Now it's M-58 and M-84.

Not sure if the top one counts, because I-394 is still US-12.
If it does then this also counts:

Glastonbury, CT (original corner of Main St and New London Tpke, and ignoring Hebron Ave for clarity):
NE 17 and SH 104
CT 2 and CT 15
CT 2 and CT 17
CT 2A and CT 17A (briefly)
no numbered routes now

So "Route 17" came back, in a different outfit (NE 17 and CT 17 are not related). Any examples where two route numbers "came back" (especially if they switched)?

What other city intersections have completely different route numbers than in earlier days?

Really the entire Four Corners area has had way too many renumberings like this. Cortez, CO would be another good example (although the actual location of the route junctions may have shifted around a bit): it was originally the junction of US 450 and US 666, but it now has US 160 and US 491.

But in my opinion, the one that really stands out is Monticello, UT. That is a simple three way intersection that has been served by six US highways over the years:

Early 1920s: SR-9
1926: US 450 (legally SR-9)
1927-1939: US 450 (legally SR-9) and SR-47
1939-1970: US 160 (legally SR-9) and SR-47
1970-1977: US 163 and US 666 (legally SR-9 and SR-47)
1977-1981: US 163 and US 666
1981-1985: US 163, US 191, and US 666
1985-2003: US 191 (unsigned US 163) and US 666
2003-2008: US 191 (unsigned US 163) and US 491
2008-current: US 191 and US 491

In Fremont, Nimitz Freeway at Mission Boulevard in the 1960s was Routes 17 and Route 21 (with Route 9 continuing on from Nimitz to 21 north); since 1984 has been the junction of I-880 and Route 262.

In Los Angeles Arroyo Seco Parkway at Golden State Freeway was originally the junction of US 6, US 66, and US 99, but is today I-5 at Route 110.  Several miles southeast in East Los Angeles, the Santa Ana Freeway at Long Beach Freeway interchange was originally US 101 at pre-1964 Route 15, then was I-5 at Route 7, and is now I-5 at I-710.

I-110 at Route 1 in San Pedro was originally Route 11/US 6 at US 101A.  Likewise, in Long Beach, I-710 at Route 1 was originally Route 15 at US 6/US 101A/US 91.

The split between the Capital City Freeway and the North Sacramento Freeway near Arden Fair Mall was originally US 40 and US 99E, but is now Route 160 at Business 80/unsigned Route 51.

San Diego has several:

Route 163 and I-8 was originally the junction of US 395 and US 80
I-5 at I-8 was originally US 101 at US 80
I-5 at Route 163 was originally US 101 at US 395
I-8 at Route 125 was originally US 80 at Route 67 briefly

The I-10/Business I-10 (Jefferson Street) interchange in Indio was originally where US 99 split off US 60/70.


In Mojave, Route 14 at Business Route 58 is the former junction of US 6 and US 466.

I-215 at Route 259 in San Bernardino used to be the junction of I-15/US 395/US 66/US 91 with Route 18.

Route 70 at Route 65 in Linda (south of Marysville) was originally Route 24 at US 99E.  I THINK that the current junction of US 395 and Route 70 north of Reno was originally pre-1964 Route 7 with Route 24.

South of Torrance, today's Route 1 and Route 107 junction was originally 1934-1937 Route 3 at Route 7.

In Berkeley, today's intersection of Route 123 with Route 13 was originally Business US 40 at Route 24.

Near Lathrop, what was once the junction of US 48 and US 99W is now today's I-5/Route 120 interchange.

In Vallejo, what had been the 1935-1964 junction of US 40 and Route 48 is now I-80 and Route 37.

Today's I-580/I-80 split in Albany was originally US 40 and Route 17.

The Route 273/Route 44 junction in Redding was originally US 99 and 1934-1935 Route 440.

One that doesn't count but yet is an interesting footnote (and has been discussed extensively on these forums) - the Y interchange still awaiting to be built between the Route 132 expressway realignment and the Route 99 freeway was originally planned when 132 was to have been I-5W and 99 there was to have been I-5 south of that point and I-5E north of it.

I found 2 changes related to the Iowa 1969 highway renumbering:
1. The previous Iowa 17 and Iowa 64 in Panora became Iowa 4 and Iowa 44.
2. This is a concurrency, so it may not strictly be what the OP was after, but the concurrency through Pomeroy went from IA 17 and IA 5 to IA 4 and IA 7.
