Interstate and US route in same state junction a number of states away equal to

[NE2]

their difference

US 69 and I-70 are both in Missouri and intersect in Kansas. Any more? What if the Interstate has to have exactly 56 exits between the state and junction? What if a sheep fucks a duck?

US 26 and 30 intersect 4 times in Idaho

Yeah what if a sheep fucks a duck?  I know they won't reproduce but like that will make you think of life.

US 6 and 44 intersect three times.....twice in Connecticut (Hartford, Manchester) and Rhode Island (Providence)

There are reasons why I did not miss this guy.

US 31 (no suffix) is in Kentucky, but does not intersect I-65 until Indiana.

Wrong shitty thread.

Interstate 74 and US 74 have a difference of zero, and intersect in North Carolina, which is zero states away from North Carolina where both routes exist.  There are 56 exits between the state and junction if you continually loop back and forth through their crummy incomplete concurrency by exiting and reentering in the opposite direction.  You may choose to exit by crossing the median if so desired.  The junction is in the state itself so this doesn't make any sense, but it still counts because I said so.  The sheep will find the duck is not all that it's quacked up to be and will duck the duck's calls.

What if a sheep fucks a duck?

Whatever happens, it won't be pretty:

When they pair off with mating partners, often one or several drakes end up left out. This group sometimes targets an isolated female duck, even one of a different species, and proceeds to chase and peck at her until she weakens, at which point the males take turns copulating with the female. Lebret (1961) calls this behaviour "Attempted Rape Flight" and Cramp & Simmons (1977) speak of "rape-intent flights". Male mallards also occasionally chase other male ducks of a different species, and even each other, in the same way. In one documented case of "homosexual necrophilia", a male mallard copulated with another male he was chasing after the chased male died upon flying into a glass window.[27] This paper was awarded with an Ig Nobel Prize in 2003.[28]

I-80 and US 46 are both in New Jersey and junction 34 states away in New Jersey.
Also, U-46: I-980?

[hbelkins]

I-26 and US 25 are both in Tennessee. They intersect in North Carolina, one state away.

How about US-101 and I-5 they run into each other at their ends such as the East LA Interchange in CA and in Olympia, Washington in the Puget sound.

[sipes23]

Illinois 72 and I-90 cross each other several times near Chicago, but not at all near Seattle.

Does US 1 count?  It's a lovely road. 

[agentsteel53]

I-8 and US-8 are 8 states apart.  they do not intersect, but neither do sheep and ducks.
