| I would suggest adding Minneapolis/St. Paul as a bonus- while it doesn't technically fit the description of a "single" interstate, I-494 and I-694 do form a loop around the city and functionally act as a single highway (they are given different numbers to distinguish the part north of Highway 94 (I-694) with the part located south of I-94 (I-494), most likely to make navigation easier for tourists entering the city) |
