"Tongue" routes

[Alps]

Couldn't think of a better name. These are loop routes that head out from the parent route and back in a loop wider than they are tall.

Examples:
* I-277, Charlotte
* Loop 202, Phoenix
* Hambley Blvd., Pikeville KY


I know there are some Business routes out there with this property. Tack on!

Truck PA 641 – notably provides an excellent view of the western portal of the Kittatinny Mountain Tunnel.

Maine has a few...
-US 1A (both the Bangor/Ellsworth and Machias ones)
-ME 186 near Winter Harbor
-ME 187 near Jonesport
-ME 102A on Mount Desert Island
-ME 230 in Trenton
-I'd go as far as to say that US 1 in the entire Downeast region of Maine is tongue-shaped

[dfwmapper]

I-10, downtown New Orleans (off I-610)
Both halves of I-275, Cincinnati
I-265 eastern half, Louisville, once the new bridge is done
I-270 northern half, Columbus
US 101, Olympic Peninsula, WA

If logically continuous routes that change numbers in the middle count:
I-280+I-680, SF Bay Area
I-270+I-259, St. Louis

When you say loops out from a parent route, do you mean only things like #XX branching off from XX?

If not, I submit M-75 off of US-131.

MA 145

NH/ME 16, probably the longest tongue route

NY 85A
NY 9J
NY 9L
NY 9P
NY 9R
US 9W ()

9R is the only one that fits.  9L & P (and 85A) are close I guess, but definitely "taller" than they are "wider".  9J & W aren't even loops.  Yeah, they meet the parent on both ends so maybe technically they are, but they're really parallel routes more than they are "loops".

Most of your interstate examples fall into the same category as 9L & P.

I-526 around Charleston, SC

I don't think we're clear on the concept yet. I believe you're looking for loop routes where the distance to the point on the loop that's farthest away from the parent route is greater than the distance between the two junctions of the loop with the parent?

Reverse tongue -- KY 1571 in Estill County. Both ends are at KY 52, but in this case KY 52 loops around and KY 1571 is the straighter route.

I-405, WA

I assumed when Steve said "wider than tall" , he meant in relation to the parent route. So we're talking about routes where the x distance is greater than the y, right?

That's what I gathered, but it makes more sense in your picture than in my words. :-)

Yes.

BUS I-15, Great Falls, MT
BUS I-35, Ames, IA (but barely noticeable)

Also CT 162, CT 142, CT 146, part of CT 154, part of CT 156, CT 215, and US 1A. Part of CT 30 from South Windsor to Rockville functions as a tongue for CT 74, although one has to use a short stretch of CT 194 to access 74.

Like US 101 and Alt US 101 near Ilwaco, WA. The Alt route is half a mile. The "main" route is 6 1/2 miles and passes through two towns.

[The High Plains Traveler]

MN-330, off U.S. 14 and through the University of Minnesota Southwest Research Station. This is just west of Lamberton, if it helps. I haven't driven it, and neither has Google Maps.

[DandyDan]

BUS I-15, Great Falls, MT
BUS I-35, Ames, IA (but barely noticeable)

BUS I-35 in Clear Lake, Iowa is much more noticeable.

Nice diagram!
