Well, how do you explain this map then:

Or this one:

Greensboro Urban Loop

Or this one:

They all show the loop carrying multiple designations.

Ok. Columbia SC: 26, 77, 20

Norfolk, VA: 64, 264, 564, 664

Washington DC: 95, 495

Baltimore, MD: 695, 83

Pittsburgh, PA: 79, 279, 376

Cleveland, OH: 90, 490, 71, 480

Ann Arbor, MI: 14, 23, 94

Grand Rapids, 6, 96, 196

Kansas City, MO 435/470 or 35/635

Dallas, TX: 635, 20, and either 408/12/35 or 161

Again - it's not that uncommon.

I'm not talking about a 'circle' having concurrent routes. I'm talking about the circle having ONE designation that lasts the entire route. Just pulling one of your 'examples':

I-495 Washington:
Interstate 495 (I-495) is a 64-mile (103 km) Interstate Highway that surrounds Washington, D.C.

Keyword: surrounds
The map on wikipedia will show you the same.

Right, even with concurrent routes, which IS common, ONE of them, generally the 3-digit number starting with an even number, is for the entire length of the route, like the ones you mentioned.
