What is your favorite piece of interstate in your state?

Doing this for Iowa is tough. I am inclined to go with I-235 through Des Moines because it's fast and doesn't get the truck traffic I-35/80 gets.

Except I-235 has the permanent speed cameras.  I-80/I-35 doesn't have any for now.  I used to use I-235 more through Des Moines, but now find the risk of a camera ticket is enough of a trade off to put up with I-35/I-80.

In Kansas, it's the section of I-35 that goes through southern Chase County.  The heart of the Flint Hills.

Definitely the winner for me too, hands down.

But it's my least favorite stretch of Interstate when there's ice or heavy rain.  Drainage along that part of the KTA leaves something to be desired.

You know, for all the love Glenwood Canyon gets for I-70 in Colorado, I think De Beque Canyon (Mesa County) really deserves honorable mention.

For PA
6) I-99 with the US 322 overlap

Really? I love 99 south of Port Matilda (i.e. where 322 splits off). Long, straight freeway for twenty miles with stunning views and almost no traffic... perfect place to figure out how fast your car can really go obey the speed limit at 70mph.

I-80 through the Poconos is pretty nice. It may not be interstate - yet - but US-15 (future 99) north of Williamsport to the state line is a beautiful drive. Actually, leaving aside that it's boring as hell, most of I-80 in PA is a really nice drive.

Am I allowed to split directions? I-99 north from exits 39-68 is fine... but southbound on that stretch is amazing. Slight downhill, perfect views to the right, 80mph traffic pace on the slow end. It's perfect.

Minnesota, I nominate:

I-90 entry from Wisconsin. Hugs the bottom of the Mississippi River bluffs with a quick climb to the Nodine exit.  Best views heading eastbound.  Unfortunately, that's it for scenery as I-90 progressively become extremely level with few trees and lots of flat cornfields all the way to South Dakota. 

1-35 descent into Duluth. Biggest grade change on a MN interstate with a commanding view of the port of Duluth and Superior harbor and Lake Superior.  An unusually narrow median also. 

I-35W approaches to downtown Minneapolis, NB and SB.  Great views of skyline.  Major reconfiguration of the freeway south of DT under construction now.

Milwaukee's interchanges - though not as good as the ones in Texas.

My WI pick is I-94 between Osseo and Black River Falls, especially the section between WIS 95 and WIS 121. Gentle yet long ascents and descents through the rolling central WI farmland.

For scenery, I agree.

I would also nominate I-794 NB across the Milwaukee Harbor on the Hoan Bridge.  Fun view of skyline with Lake Michigan just below.

From back when I lived in Illinois, my favorite was I-24 from Tunnel Hill to Vienna.

Not in Ohio, but in the Cincinnati metro area, I-71/75 Northbound approaching the Brent Spence Bridge:

From back when I lived in Illinois, my favorite was I-24 from Tunnel Hill to Vienna.

I would go with this same section but extend the eastern/southern limit to be to the start of the flat section prior to the Big Bay/New Columbia interchange.

For second place, I would go with the ascent/descent west of the Illinois River bridges on I-72.

[TravelingBethelite]

It's hard to choose on account of how binary Missouri's interstates are (urban traffic & suburban hell vs boring plains, for the most part). That said, I've enjoyed I-44 between Springfield and Rolla every time I've been on it. The Meramec Caverns signs are my favorite part to boot.

1-35 descent into Duluth. Biggest grade change on a MN interstate with a commanding view of the port of Duluth and Superior harbor and Lake Superior.  An unusually narrow median also.

The section from Boundary Ave to US 2 was more or less overlaid directly onto the existing US 61 expressway. There are still remnants of the original Thompson Hill rest area which I-35 was partly built on top of, but they're not really visible from road level.

I was going to say - such a short section! What makes it stand out?

I was just thinking small.  As a whole, I enjoy the entire section from I-57 to the Kentucky border.
