Highways with the same number that intersect

[bugo]

This thread is intended to be a complete list of highways with the same number that intersect. Interstates that "turn into" state highways like I-440 and AR 440 do not count. I-41 and US 41 do not count either. Here's a start.

US 27/GA 27
US 70/TX 70
I-74/US 74
US 360/VA 360
US 287/MT 287
US 95/AZ 95
I-64/IN 64

"Almost"
US 59/AR 59
US 30/UT 30
US 89/WY 89

Which ones am I forgetting? Do CO 24, CO 36 and CO 40 still exist, and do they meet their respective US highways?

[Hurricane Rex]

Am I right to assume that suffixes do not count? Example Interstate 35W and 35 E.

In Oregon there is a near miss between I 82 and OR 82. Although they are 50 miles apart, in the Origional interstate plan, I 84 was to be signed as I 82 and OR 82 already existed at the time. I'm already surprised to see this many intersections.

NY 90 crosses over I-90, but there is no interchange.

[jakeroot]

There's a few states where this isn't possible. Washington and Utah come to mind. I thought Oregon was the same way, but ^^ evidently not.

I-20/GA 20

Pretty sure we've had this thread before.

Pretty sure we've had this thread before.

Possibly more than once...

Here is a more recent iteration:  https://www.aaroads.com/forum/index.php?topic=20643.0

Now we have two threads with the same subject intersecting in a forum...

I-74/US 74

I'm not sure where these intersect.  I-74 is a mess in NC.  The segment of it I was on last year was mostly concurrent with I-73 and US 220, making the number completely unnecessary.  A few days later, I was on US 1 heading to US 74 and there was NO I-74 signage there.  From the maps I've seen, I haven't seen anywhere where I-74 and US 74 cross or split.  I-74 just randomly shows up in various places.  NC is doing us no favors by signing it in broken segments.

That said, it's also I-73, and it intersects NC 73 west of the Sandhills area, so that one can be added.

I-74/US 74 intersects US 74 Bus and US 74 ALT all at the same interchange.  There is no one angle to see all 4 shields but here it is:

In the days before the Interstate system, it was supposed to be a single number for a single type. Older versions of the highway commission document "Descriptions of OR and US routes" stated that Oregon Routes 228, 230 and 297 were not to be issued so as to reserve the numbers for potential US route expansions. Only those numbers were reserved because Oregon's secondary route system only used 2xx numbers at the time. Of course, both OR-228 and OR-230 were assigned in that same document. IIRC after US-26 was extended into Oregon and US-28 was deprecated, the number changed to OR-226/US-226 that was reserved. I'll have to dig out the documents when I have more time and extract the exact text to post here.

Oregon also has about as far of a miss as you can get within the state with I-205 and OR-205.

I-695 and MD 695 is a strange case.  Google Maps and Apple Maps show a MD 695 on Broening Highway that leads to Dundalk Marine Terminal, but it officially known as MD 695A.  Meanwhile, MD 695 is the official designation of I-695 between the northern junction of I-95 and I-97.

[1995hoo]

US-360 and VA-360 famously (amongst roadgeeks) meet at an intersection where the signage has auxiliary "US"  and "STATE"  signage.

[KeithE4Phx]

US 95 and AZ 95 meet at I-10 in Quartzsite AZ.

A future instance is I-69 and US 69 around Lufkin, TX.

[Hurricane Rex]

A future instance is I-69 and US 69 around Lufkin, TX.

Which is against interstate rules. I remember reading that Interstates and US highways with the same number can't be in the same state. I 69 was amusing enough before but this gives it a little extra value.

[Max Rockatansky]

I'm surprised nobody has mentioned US 1 and A1A.

I-24 and US-24 in Illinois say hello, even though they're in different parts of the state.

Tell that to Wisconsin.

I-64 and IN 64 intersect
I-265 and IN 265 are connecting segments of the same highway

IL could have expanded it first beyond US 24 and I-24. US 51 would have been just fine, grid-wise (or at least close enough), as I-51 north of Bloomington-Normal into Wisconsin, in lieu of I-39. 20/20 hindsight

There's a few states where this isn't possible. Washington and Utah come to mind. I thought Oregon was the same way, but ^^ evidently not.

Also California and Massachusetts.

Yes and no for Massachusetts.  The only exception to the no duplication rule in MA is I-295 and MA 295.  Of course, they're at opposite ends of the state and both are continuations of routes from another state.  CT, RI, VT, ME, and NJ have no duplication at all. NH only has 1: US/NH 4 as the result of a continuation of ME 4, and they come within 5 miles of each other.   PA only has 3 duplicates (86, 99, and 380); the first 2 were the result of interstates that came much later, and the last one are routes that are over 300 miles apart.  DE only has 1 exception that qualifies (US/DE 202 doesn't): US 9 and DE 9.

[TheHighwayMan3561]

A few states like MN and WI had non-duplication policies until specific instances came up; here it was MN 62 (the two are about 100 miles apart) and in WI it was I-39 coexisting with WIS 39 separated by about 40 miles.

There are a few of these signs posted on US 41 to avoid confusion between the two 64s. https://goo.gl/maps/vj9FTDE1qiR2
