not a re-entry into a state, but I-8 crosses between San Diego and Imperial Counties about five times.  The county border is a straight line drawn over a mountain range ... the freeway is somewhat more winding.

Did you know: I-90 is the only interstate to have both its termini with non-Interstates.

What about I-75? It's northern terminus is at the International Bridge in Sault St. Marie, and it's southern terminus is at FL-826.
Barring interstates that hit borders.  I forgot to mention that.  By that rationale, I-75 is eliminated.  Anyway, I-90 is almost 2000 miles longer than I-75.

Actually only 1234 miles longer; I-75 is 1786 miles long, while I-90 is about 3021 miles long.

When I-86 is (ever) complete in NY, it could be considered the only Interstate to enter a single state more than twice, no???

I-24 enters Tennessee twice since it briefly dips south into Georgia.

they've raised it in Utah as well?

last time I was there, I went from 15 to 70, and didn't see anything.  I'd imagine that the area south of 70, down to about St. George, would be eligible for the higher limit too ... pretty abandoned stretch going in both directions from 70.

oh and 70 itself should be eligible for speed limit 80.  There are a few winding mountain sections, but it's a very lightly traveled road.

Jeff sent us an article on the 80 mph limits in Utah back in January:

The highest exit number in the country is 880 (I-10, Texas).

The highest exit number on a sequentially numbered highway is 100 (I-395, Connecticut, continuing numbers from the CT turnpike).

US 90 is the only highway in FL to enter two sets of counties twice each in its trek through the state (Holmes/Washington and Leon/Jefferson).

Before I-65 in Nashville was rerouted over the former I-265, the junction on the southeast corner of the inner loop was a rare junction of three 2dis with each leg being multiplexed.

Former alignment:
West leg: I-40, I-65
North leg: I-24, I-65
East leg: I-24, I-40

With I-65 out of the equation, it's just another interchange.  Though I still travel north/south on the old I-65 alignment and not the new one.  Outside of rush hour, it's faster.

When I-86 is completed in NY it will beat this with 131.

H is the highest-lettered exit without a number!  2Y is in Kansas City as many know... who knows where the H is?
I will guess Atlantic City, NJ since they are pretty hardcore on the lettered exits.
Here, perhaps?

The section of expressway that has the longest continually lighted section is I-95 from the NY State line to just east of Branford, CT.

I-45 is the shortest 2di ending in 5 in the Interstate system, at 285 miles.  It is also the only intrastate x5 route.

There's an approximately 40 mile stretch of I-81 where you can cross three state lines and, hence, be in four states in less than an hour.  (Maybe a half-hour if you push it.  :wow:)

Starting in Virginia at exit 323, you cross into West Virginia for 26 miles, then you make a 12 mile sojourn through Maryland until you enter Pennsylvania.

The longest stretch between exits on an Interstate Highway is located on the I-80 in Utah between Wendover and Knolls, with 37 miles (60 km) between those exits.

Yup you're right.  I-94's the longest, but I-81 is still the longest N-S route of the above criteria.

That beats I-70/76 on the PA Turnpike between exits 110 and 146 (36 miles) by one mile.  (mentioned earlier in this thread)

BTW It would be interesting to know the exact distances between both pairs of exits.

The longest interstate that doesn't cross a state line? I-87. 333.49 miles, all in New York.

The shortest interstate that does? I-535, extending a mere 2.78 miles south out of Duluth, Minnesota into Wisconsin.

The 405 is the busiest freeway in the United States with an average of 380,000 vehicles per day.

I take it that would be the 405 in Los Angeles, not Portland, Oregon. The actual busiest stretch might be the section between LAX and the San Fernando Valley; there's no such thing as rush hour on that stretch; it's congested (both directions!)from about 6AM to about 8PM or even later.
