Best “roller coaster” roads

[Ketchup99]

US 322's divided section from Tusseyville to Milroy. Speed limit 55, truck limit 20. Sharp curves, steep incline. Super, super fun drive.

[Rothman]

Practically any back road in central and northern PA.  Be careful with your suspension.

I'm thinking something in Missouri should be in the higher tiers - perhaps parts of US 160?

Agreed, especially MO-19 in the Current River region, in addition to MO 125 south of Sparta, which is in the same "White River Hills" region as US-160. However, MoDOT recently started a project to make the so-called "Tecumseh Curves" less curvy (Revive 755's second link).

MN 50 between US 52 and US 61 has the roller coaster effect, but it's a straight shot.
MN 18 in rural Pine County has some of that too.

MN 1 east of US 53 is pretty damn nice and has lots of curves out in the Iron Ranges.

Many of the town roads and county highways in the hilly Driftless Area of Southwest Wisconsin would qualify. Most of these roads are built to the lay of the land, with very few road cuts. Some can be straight and hilly, and others are both curvy and hilly. One of my favorites is Holland Rd. in Lafayette County, just west of Darlington. The stretch from CTH Z west to CTH O is probable the best stretch.

Another is the aptly named Roller Coaster Rd just southeast of Darlington.

But just about any county highway or town road in Lafayette, Iowa, or Grant counties in southwest Wisconsin could be considered a roller coaster.

The "Rim of the World Highway" in the San Bernardino Mountains has lots of horizontal curves. And CA-138 between the western junction with CA-18  and CA-2 has lots of vertical curves

CA 243/Panoramic Highway and CA 74/Pines to Palms Highway are also worthwhile for the "roller coaster"  purpose in the same vicinity.

I've brought this up on similar threads, but Adirondack Drive between Farmingville and Selden, New York has to be on a list like this.

Waterway Drive in the Lake Barcroft neighborhood east of Annandale, Virginia. You can't go too fast because it's a residential area, but the divided segment in particular is a fun little roller coaster.

(For those of you who have visited Kings Dominion, Waterway Drive's roller coaster is like the Scooby Doo roller coaster aimed at the younger demographic, whereas some of the other roads named above are more like the Rebel Yell or the Grizzly.)

Kennon Road has a rollercoaster factor for roads in the Philippines heading to the Baguio city area.

All of the Missouri Ozarks.

122nd Ave in Allegan County, Michigan

Heh.  Just thought of the "ski slope" in northern Manhattan, upper east side.

The Breezeway - part of intercounty route C-48 in NW Lower Michigan:  http://www.ridethebreezeway.com/

As kids we always liked Egypt Valley Road in Kent County.  I'm not sure how many hills it actually has, but I think there were some.  At the time it was gravel; we looked out the back of the station wagon (look it up youngsters) to see the dust cloud and said that the butterflies were coughing.

CA 2 in Angeles National Forest.

A few examples of what would likely be considered "roller coaster" roads here in CA:  CA 108 over Sonora Pass,  the National Park road that is functionally CA 89 through Lassen Park, CA 168 east of US 395 to CA 266 near the NV state line, and one of the most fun SoCal entries, CA 33 from Ojai to CA 166.  Except Lassen Park/CA 89 during the summer (in non-COVID years, of course!), most of these roads don't see a huge amount of traffic, so they're pretty enjoyable to drive without having to constantly put up with the whims of your fellow motorists.

89/Lassen Park Highway was a blast during COVID, hardly a person in sight last year.  Some others they come to mind up in that part of the state are; 96, 299 and 36 east of US to I-5.

VA 6, especially west of Scottsville.

US‐550 between Ouray and Durango is full of switchbacks.  And I get to drive it regularly for my work! 

Granted I have to stick closer to the speed limit than most as my company monitors my speed and harsher cornerings, but it's still a fun drive in my Ford Transit van.

Box Canyon Road east of Coachella, California (former US 60/70 and CA 195) has some good rolling movements.  It was built on sandy soil in the days before highway engineering emphasized gradual elevation changes.

That poor grading is what led to a lot of it being wiped out a couple years ago after it washed away.  It was a lot of fun to drive the repaired/resurfaced roadway back in late 2019.

I just got back from a bunch of twisted roads in southeastern Ohio.  Particularly memorable was Ohio 565 and other highways in the vicinity of southeastern Noble County, and the gravel roads I was dumped onto after driving Ohio 621 north of Coshocton.  Possibly the most Amish area I've ever seen, to boot.  Ohio 342 was a really fun road to drive, too.

I haven't driven it in awhile.  If they had to do spot repairs due to washouts, I don't imagine my Mustang would handle it very well these days.

It was more of they had rebuild the entire roadway, it was pretty much obliterated.
