Commonly confused routes

[hotdogPi]

* I-95 and MA 128 when they aren't together

* Interstate 84, 86, 88 (confused with the one on the other side of the country)

* I-74 and US 74

* NY 25 and NY 27 (or maybe it's just me, I'm not sure)

* I-86ESSSSEEEEEEE and 86ESSSSEEEEEES

* I-287 and I-278

* MN 11 and ON 11 (again, not sure)

* US 66 and OK 66

* I-93 and MA 3 (on the Weather Channel)

I always mix up I-5 and US-70.

NJ 3 and NJ 495
NJ Turnpike and GS Parkway (this actually happens, I've heard)
NJ 139 and US 1&9
NJ 7 and CR 506 ("Belleville Pike becomes Route 7")
AC Expressway and NJ 42 freeway and I-76 (and then I-676)
NJ Turnpike and I-95

NJ 3 and NJ 495

I've seen/heard NJ 495 mistakenly called I-495 too many times to count. Even NYCDOT and NYSDOT screw this up by policy - plenty of I-495 shields pointing to the Lincoln Tunnel, but not a single NY or NJ 495 shield to be found anywhere in Manhattan.

But I can't recall ever seeing/hearing it confused with NJ 3.

How about Suffolk CR 111 and NY 111?  A lot of people heading out to Montauk get off the wrong exit because they don't know that there's both a county route and a state route with the same number.

Also, Montauk Highway is NY 27A, Suffolk CR 85, Suffolk CR 80, and NY 27.  No one but a serious roadgeek keeps track of where the different designations start and end.

The way to the tunnel is Route 3.

Il-394 is missed called I-394 by many


IL-390 was missed called I-390 on the radio on the day it got numbed.

US 20 and 26 in Idaho and Wyohming

[Occidental Tourist]

I-305 and US 50.
CA 480 and empty airspace 40 feet above The Embarcadero.
I-405 and my local mall's parking lot on Black Friday.

[cpzilliacus]

Capital Beltway and any other freeway in the metropolitan Washington, D.C. area.

Baltimore Beltway and any other freeway in the metropolitan Baltimore  area.

[SD Mapman]

US 87 and SD 87 by the NPS. (Street View)

[NE2]

I-86ESSESSSEEEEEEEES and I-86ESSESSSSESSESE

[Dr Frankenstein]

A-30 and any of its spurs (530, 730, 930).

132 and anything it's multiplexed with near Montreal (A-15, A-20). But I agree it's a clusterfuck near the Champlain Bridge. A-20 and A-25 get mixed up in the area too.

[Doctor Whom]

Capital Beltway and any other freeway in the metropolitan Washington, D.C. area.

I once read in a newspaper about the beltways leading into Washington, D.C. 

In Maryland, I-270 and I-270 West Spur (secret I-270Y).

In Virginia, Rte. 110 and the GW Parkway.

In D.C., any of the n95's.

The direction of I-64 in Hampton Roads.

NJ Turnpike and GS Parkway
NJ Turnpike and I-95

These are easy mistakes for people from states like IN, OH, PA, where there's only one Turnpike and that Turnpike carries a major Interstate most of its length. When I was a kid on a roadtrip to Nova Scotia, I thought GSPkwy, NJTP, and I-95 were the same road.

The same can be said for NJTP, which is the only Turnpike and carries I-95 for nearly 60% of its length. And PA Turnpike has more extensions that are not I-76 than the NJ does. If anything, NY is much more confusing, what with the Thruway and I-87 and I-90 and I-287 and I-95 being on different parts of the Thruway system and having long segments that are not on the Thruway system.

GS Parkway is another "Turnpike" as fas as I'm concerned.  I (and presumably other Ohioans) sometimes refer to the Indiana East—West Toll Road as "the Indiana Turnpike".  As for PA, the only "branch" of the Turnpike I was familiar with at the time was the NE Extension, and that's all the way at the far end of the state so it's easily missed.  Even now I'm not sure if all the other Turnpike sections existed back then, and I think awareness of those is generally fairly low outside of the areas they serve.

Il-394 is missed called I-394 by many


IL-390 was missed called I-390 on the radio on the day it got numbed.

Tack onto that one Illinois 53 and I-290 (between I-90 and I-355).  It's I-290 but called "Route 53" even though 53 hasn't gone south of Biesterfield for years.

I-495 in NJ was never called it, and NJ 495 as its been for over 30 years is still called Route 3 as that number was retired almost 50 years ago.

NJ 139 is still called Route 1 & 9 (or One and Nine) and traffic announcers do not help either.

* Interstate 84, 86, 88 (confused with the one on the other side of the country)

Forgive me, but I'm going to have to call BS on this one.

(scene: Middletown, NY)
"Pardon me, sir, but can you tell me how to get to Jamestown? I'm on my way to a Lucille Ball convention..."
"Sure, just get on Route 17 heading west, follow that out to Interstate 86...."
(interrupts) "Interstate 86?"
"Yes–when you get to Elmira, you'll start to see signs for I-86..."
"Oh Elmira..."
"Yes."
"...as in New York."
"Yes."
"For a moment there, I thought you were telling me to go to Pocatello, Idaho!"

US 66 does not exist so it can't be confused with OK 66.  However, in many places there are several different former alignments of US 66 which can be confusing.

A good example of roads being confusing is Siloam Springs/West Siloam Springs, where AR 59 comes within a mile or so of US 59.

How does NC do it with both I-74 and US 74 which are not near each other, not on top of each other either, but on each other?
