Title: Highways where each terminus is a palindrome of the other
Post by: ElishaGOtis on November 18, 2024, 08:03:42 AM
Probably best described through an example... I-24 goes between I-57 and I-75. What other highways do something similar where one terminus ends at a number opposite the other?

I'd like to shy away from routes that are a palindrome regardless, like I-55 or US-202, mainly because I'm thinking of cases where the palindrome is a different number entirely (I.e. 57 and 75, or 01 and 10).

Illinois Route 22 goes between US 14 and US 41.

CT/MA 41 goes between Dutchess CR (0)2 and US 20

M-100's south terminus is I-69, north terminus is I-96.

M-204's western and eastern termini are both M-22.  Does that count?   :bigass:

ND 67 runs from US 12 to ND 21.

Both WA 155 and WA 211 run between WA 20 and US (0)2.

Stretching this further, MT 56 runs between MT 200 and US (00)2.

I don't think there's any highway in Oregon that does this exactly. Our route numbering scheme doesn't really allow for this to happen. Xonhulu also listed the examples we have in Washington, so really, I don't know what to go for here PNW wise, considering I'm not very familiar with Idaho. More familiar with the Pacific Southwest state wise.

I think California's geographic numbering scheme from 1934 mostly prevents this from happening, i.e. Route 20 is way up north from where Route 2 is as a result.

That being said, there are some that may have been possible due to post-Interstate changes:

- Route (0)1 and I-10 as termini: almost-but-not-quite for I-710 on each end. 
- Interstate (0)5 and US 50 as termini: the forthcoming Capital Southeast Connector, though not sure this will be a numbered route

FM 1013 in Texas? I believe it connects US 69 to US 96.

TX 327 definitely does.

FM 1013's west terminus is at US 69, but the east terminus is past US 96 by a few miles.

I thought Rec.Rd. 255 might, but it goes on past US 96 to the south end of Toledo Bend.
