Longest distances between freeway exits

[kphoger]

WI: 13.5 miles between the waterpark exit and the skiing exit. (can you guess where those exits are?)

I thought the longest in WI was on I-90 passing through Fort McCoy.

As I measure them, the two stretches are the same length.  Maybe one could split the hairs more finely than I did to find out the correct answer but, for me at least, they're a tie.

I will be that man. But I also have found something of a discrepancy. Going by the mileage points as listed on the Wikipedia, the distances are as follows:

Exits 28 to 41: 13.24 miles
Exits 92 to 106: 12.60 miles

But if you measure from bridge to bridge on Google Maps, you get the following:

Exits 28 to 41: 13.2 miles
Exits 92 to 106: 13.5 miles

That second one is way inconsistent, for some reason. So, who knows. I'm inclined to go with the Goog, though.

I'll go with google if you measured it pretty accurately with the ruler tool. Like when I made fictional exit numbers for US 36 in various states a while ago, almost all of the wikipedia mileposts on the section between Boulder and Denver are 7 miles lower than what I got out of the ruler tool, so I just went with the ruler tool results for my exit numbers.

You have sort of I-895 in Maryland.  It has all partial interchanges on both sides of Harbor Tunnel so anyone entering from its south end from I-95 has to travel 8 miles to Childs Street to exit even though many ramps lead on in between.  It used to be longer as Childs Street is a newby and the first exit prior was Holibard Avenue north of the Tunnel being close to 11 miles from the south end.

How does one define 'distance between exits'?  Is it from bridge to bridge, or from gore point to gore point?

I see bridge to bridge used the most, as with Wikipedia's exit lists in most cases. The mile marker at the bridge is where the exit number comes from in most places, how it rounds at like a x.9 mile marker can vary.

been up there a couple of times, lemme guess without referencing a map

waterpark one is the easternmost exit for Wisconsin Dells with US 12
ski one, I don't remember the road it exits too, but it's one west of the I-39 exit

Ding ding ding! It's WI-33.

Nope. That's 12.5 miles.

FWIW I measured 13.3 miles between the westernmost merge point of the WI-33 exit and the easternmost merge point of the US-12 exit, did the same between the WI-131 and WI-71 exits, and got 12.5 miles.

If not a winner, a contender: G7 in Inner Mongolia, at 179 km, or 112 miles (there are two intermediary full trumpet interchanges, but go nowhere as of yet according to Satellite View).

Then a 294 km/184 mile here:

You missed two exits in that supposed 294 km section. It is only half of that: https://www.google.com/maps/dir/41.7021059,103.1393613/42.0207531,101.5265201/@41.9335939,101.8637033,119052m/data=!3m1!1e3!4m2!4m1!3e0!5m1!1e4. However, there's another 98 km (61 mile) gap East of this.

The longest exit gap in Spain is the 52 km (32 miles) between exits 3 and 4 of AP-2. Toll-free freeways (some may consider this a redundancy) have more exits and closely spaced, but I know two 17 km (11 mile) gaps on A-23.
