Taking numbers of two us routes to form another in a state

[roadman65]

I was noticing this one here.  In New York you have both US 20 and US 2 and if you put the two route numbers together you get 20-2 or 202 which incidentally is another US route within NY.

Also I have found that in neighboring Pennsylvania you have US 1 and US 19 which comes to 119 and, of course PA has a US 119.

Then finally Georgia has both a US 1 and US 23 within its borders and has a US 123 which features all the numbers in succession if you pair it as US 1 and US 23.

I picked my brain to find other routes ( US routes only) that you can do that and come up with another route number of the same without rearranging the numbers.   Or is there others that you can think of.  If anyone even considers Maine with US 2 and US 1 to become US 201, it does not count as zero is a whole number as far as this is concerned.

The closest Connecticut would get is 1+5=6. Seeing as we have US routes 1, 5, 6, 7, 44 and 202 here, your math won't happen.

1 1 11

Wisconsin and Michigan both have US 10 and US 2 = decommissioned US 102

i'm not surprised that you picked your brain and only came up with those
1+30=130

omg :trollface: autoroute 5 + 40 = 540

[Mapmikey]

1+76 = 176
1+78 = 178
1+70 = decommissioned 170
70+1 = 701
1+11 = decommissioned 111
1+13 = 113
1+20 = decommissioned 120
1+17 = 117
1+21 = decommissioned and future 121
52+1 = 521
1+22 = decommissioned 122
6+11 = decommissioned 611
1+29 = 129
20+9 = 209
1+40 = decommissioned 140
1+58 = decommissioned (within) VA 158
50+1 = 501
1+92 = 192

US-2 and US-23 in Michigan = US-223

PA: US 20 and 6  206 (all 1/2 mile of it)

I did not see that one.  Good find.

Also I did not go all the way to it, but if I went one state east of my US 123 find  I would have US 178 from US 1 & 78, and US 176 from US 1 & 76.

Yes I forgot that one there.  I wanted to see how you and your buddy from MIT would react and I was right!  Both with Elementary School level type of mentality for two men in their thirties.  Plus autoroutes are not US routes, but you knew that one anyway.

Montana: US2 + US87 = US287

I don't think there are any Ohio examples, as our only 1dUS is 6, and I don't think we have any 3dUS starting or ending with 6. On the other hand, if we allow addition instead of concatenation, we have US 6 + US 30 = US 36.

Florida has 1+29 129

[Mapmikey]

2+81 = 281
2+12 = 212 (MT and MN)
6+41 = 641 (truncated)

[hotdogPi]

"2"+"20"="220" (NY, even though both 2 and 220 are extremely short in New York)
