Title: Concurrency/3di Homonyms
Post by: dmuzika on January 19, 2021, 01:30:24 AM
I'm wondering if there are any two concurrent highways (specifically a 1di & 2di) that are similar to an area 3di highway and thus sound the same when spoken (a homonym)?

For example, let's say that Interstates 5 & 80 overlap in Northern California (I realize in reality they don't) - the section would be I-5/I-80 and could be referenced as "five eighty". There is also an I-580 would also be referenced as "five eighty". Are there examples where this happens (Interstate or otherwise)?

The closest example of it actually happening was in Edmonton where Highways 2 and 16 shared a concurrency during the 1990s, while Highway 216 was commissioned as the developing ring road. The Hwy 2/16 concurrency was along city streets, while Hwy 216 is also named Anthony Henday Drive, so traffic reports, etc. would reference the name instead of "highway two sixteen".

Not quite what you're looking for, but To 95 / 295

Trying to thing of some examples where both numbers are normally said when referring to a roadway...

There's 1&9 in North Jersey, but that's pronounced "1 and 9". I guess that's kinda close to 109 in Cape May.

There's also 13/40 in Delaware, often pronounced "13 40"...but no 1340 route to go along with it in that state!

I-535/US 53/WI 35, and I-35 next door in MN
(https://www.google.com/maps/@46.7337945,-92.0941389,3a,75y,293.14h,93.48t/data=!3m6!1e1!3m4!1sTyyQPVZetlmEXEecG7ocdQ!2e0!7i16384!8i8192)

For people familiar with the area: How often are WI 35 and I-35 confused with each other? Those 2 highways are very close to each other north of the Twin Cities.

Fifteen and fifty are notoriously easy to confuse when spoken.

I have no idea whether they're ever referred to together, but US-1 runs concurrently with I-95 for a short distance in Pawtucket, Rhode Island, and I-195 begins (or ends, depending on your point of view) nearby in Providence.

And for that matter, so are these:

Thirteen and thirty
Fourteen and forty
Sixteen and sixty
Seventeen and seventy
Eighteen and eighty
Nineteen and ninety

Actually, I think that's a great example!  Although nobody actually says out loud "take TO-95 for three miles".  But still.

That's not what the OP is asking for.  "five thirty-five fifty-three thirty-five" does not sound the same as "thirty-five".

About a 4 mile separation, but I-91 intersects CT 2 with a single ramp (used to be a partial interchange), then intersects I-291. 

In Brewster, NY you have US 6, I-84, and I-684 all coming together at almost the same point.

No one confuses them at all. WIS 35 mostly handles local/regional traffic, and anyone going long distance is either on I-35 or on US 53 if they're going to the east.

Interesting
I thought there's going to be a similar sign like this one on I-70 WB in MD (https://www.google.com/maps/@39.6531383,-77.9074997,3a,75y,305.49h,88.09t/data=!3m6!1e1!3m4!1sQiPGlWXMqLTHqOL_VlNgQQ!2e0!7i16384!8i8192) with two routes sharing a number, one is an interstate, other is a local state route. But at the same time, it seems like MD really want WB I-70 drivers to shunpike the PA turnpike, so that may be a part of it.

Granted, I've never been to that area and am just looking at a map, but...  I'm trying to think of what traffic would even end up on the wrong road, and I just can't imagine that the amount of traffic any possible confusion would apply to would be very much at all.

I guess that would apply to most if not all 2xx Interstates. There were plenty of times when living in the Harrisburg area where I gave someone directions along the lines of "take two eighty-three to eighty-three"  and had to be careful about the pauses between words.

Locals of Raleigh NC call the US 1/64 duplex "one sixty four" so it sounds like US 164 to me

I gave directions from where I am in Cincinnati to DTW airport for a family member before. I mentioned "take I-275 till exit 43B to I-75" once, and also two different I-275, one in Cincinnati, the other in Detroit.

Here's something else: counting up all the I-275 variants, it goes through the same number of states as I-75, although there's one state different for each; I-75 in GA and I-275 in IN.

LA 1 and US 71 overlap in north Shreveport, LA and US 171 is in the same city but they've never been confused with one another. MAYBE when US 171 was routed to end in downtown Shreveport at 1/71 for a couple of decades it could have been an issue but I doubt it.
