Title: Commonly confused routes
Post by: hotdogPi on November 27, 2013, 03:32:49 PM
* 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 (https://maps.google.com/?ll=35.652484,-97.424001&spn=0.004786,0.007532&t=m&z=17)

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

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.

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.

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.

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.

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?

As a general rule, ALT, BUS and other routes can pose problems.

One example, from a wedding reception a few friends went to: Directions say to go down XYZ Road for several miles.  At the traffic light, turn left onto Rt. 553.  Destination will be on the left in 2 miles.

The problem was, there was an ALT 553 the guests will arrive at first (2 traffic lights and 1 mile before the true Rt. 553) .  With a traffic light.  And with many people being from outside the area, they wouldn't know 553 from 553 Alt.  Hell, the bride, groom & whoever came up with the directions probably wouldn't know the different either.  So there was many, many lost guests as a result of the little "Alt" that most people never pay attention to.

Dyslexics are not dysnumerics. (I've known a few, and this has come up.) The problem is when they read individual characters and try to parse it into a word - in other words, the language center of the brain. Math goes a different route.

FM 121 and TX 121/121 Toll near McKinney TX. There are signs on southbound US 75 saying to continue further south for DFW.

In Shreveport, LA on I-220 before it's western terminus, the last exit before it becomes LA 3132 is for Jefferson Paige Rd. The road is technically LA 3231 from I-220 east to US 79/80 (actually I think there is one sign in the field for it), but I'm sure they didn't sign the number on that exit for the numbers being so close.

I remember once in Haines City. FL on US 27 SB at Polk County Road 17, there used to be a "TO US 17" shield pointing straight ahead so that SB travelers there would not confuse the two.

Of course now there is a FL 17 that replaced US 27 Alternate from Haines City to Frostproof that intersects US 17 in Downtown Haines City where FDOT does not think people will get confused there on Hinson Avenue.  The SR 17 shield stands alone without a US 17 shield next to it at the intersection as well.

Pacific Coast Highway or PCH (SR-1) and Pacific Highway (US 101) in the San Diego area. Pacific Coast Highway ends in Dana Point, Coast Highway is the name south of there. Pacific Highway is the name for an old US 101 alignment in the downtown San Diego area. Pacific Highway also was the name for US 99, though not really until north of Sacramento.

OH 61 intersects Morrow CR 61. Morrow County uses the white square on all its county routes, which is not wildly different from the state route marker at a glance.  At the intersection, there's a sign for CR 61, but none (facing OH 61 traffic) for OH 61.  I'm surprised there isn't an OH 61 sign with an up-arrow next to the CR 61 sign with its right or left arrow – I think if someone isn't paying close attention, they might turn there intending to follow OH 61.

In Alexandria/Pineville, LA the US routes can be confusing until you are used to them. US 71, US 165, and US 167, plus 165 and 167 have "business" routes (not much business on either of them...) I think it's mainly the digits 6 and 7 that get one tongue-tied.

I think the confusion for me used to be that MacArthur Drive, the main drag around town, is 71/165 at one point and 71/167 at another. Also the criss-crossing of all 3 routes on the Pineville side were a pain to remember.


The best way to keep them straight was to remember those highways in Louisiana as a large X:

I feel like the 6xx series of the New Jersey County Road system would be confusing to any out of staters - if you see a CR 601 shield in Somerset County, the 601 you just found over in Hunterdon County is not the same road. To add on to this confusion, sometimes the numbers change on the same road once you pass into the next county - Mercer CR 604 becomes Somerset CR 601 is an example of this. It gets even worse when you find shields that don't have any indication of what county you're in... but the only ones I've seen these for are 5xx routes which don't change numbers through the counties. And as far as I remember, there are no 6xx shields on guide signs anywhere.

Sounds just like state highways in different states.

It appears that the 5XX county routes are Inter-County whereas the 6XX county routes are only Intra-County.

I get many of the Washington 5xx'es confused.

interestingly, I probably wouldn't have that problem if they instead numbered them 105, 205, 305, ...

I agree, especially since they're numbered in order (south to north), which leads to clustering.  If I'm driving, I'm sure to pay extra attention and don't have a problem, but just sitting here going from memory, distinguishing between 524 through 529 in Lynnwood/Everett or anything besides 539 in Whatcom County is virtually impossible.

Pretty much - except you're still in the same state.

Yeah, that's the basis of it. 5xx routes do not change from county to county, but 6xx routes do.

Not dissimilar to Virginia's secondary routes and West Virginia's county routes.

Right, but NE2's point was that these are county routes, not state routes.  So you should probably expect them to repeat from county to county, just like state routes repeat from state to state.

All county routes look the same within a state, except for the number and sometimes the county name.

State routes usually look different between states, either by shape or by pattern.

Unless you're in New England, land of the boring squares.  But still, point taken.

But I doubt two county routes in two different counties is what the OP had in mind... except you're the OP, so I'll just stop talking and go sit in the corner.

I did not have it in mind. I don't think it will be confused unless someone travels on it, since most of them are obscure.

In Washington, D.C., I-295, D.C. 295 and the southern end of Md. 201 (which connects to D.C. 295 at the Eastern Avenue overpass near Beaver Heights, Maryland) are frequently confused (even by traffic reporters) even though they are effectively one travel corridor.

My family missed the exit from US 50 west to MD 201 south because we were looking for 295. (I assume the current sign with TO I-295 was not there.)

Not true. Ohio has quite a menagerie of county route markers.  White squares and blue pentagons are the most popular, of course. Some counties use green squares.  Some attempt to use the shape of the county.  Many just put the county road number in small text under the name on blade signs.  Several put the county road number in normal size text on blade signs, because the road doesn't have any other name.  There's no statewide agreement at all.

I've even seen multiple styles within the same county, and the signs look equally new.

I don't think these are commonly confused...the CA routes are essentially extensions of the Interstate using the same highway number, all envisioned as one contiguous highway (with contiguous exit numbering). 15 & 210 are eventually to be adopted into the Interstate system.

The Las Vegas Beltway with I-215 & CR 215 is equivalent. It is simply referred to as "the 215" and is understood to be one complete route.

True, but 99% of people don't need to know the difference. They're all part of one corridor, so when you say "the 210", it doesn't make a difference if you're referring to I-210 or CA-210. They numbered them that way to reduce confusion.

EDIT: Oh, roadfro beat me to the punch.
