This can take many forms--a section of road that is now bypassed, abandoned, cut off, used for something else, etc. It's everywhere in the world. What's your favorite such section of road and why?
This is probably the last thing that would qualify, but here's some unused ROW (perhaps a bit more interesting). There was supposed to be a cloverleaf interchange here, but the freeway was never extended south.
The stub of the freeway that was to interchange with the pictured freeway below is here: https://goo.gl/UBHg1Q (note the graded dirt and concrete on either side of the railway)

Old OR/US 99W between Sherwood and Newberg was downgraded to local streets if that qualifies. Great for running workouts though.
Also, OR 18 between Dayton and McMinnville has ROW for 4 lanes but it is currently 2 lanes.
I've always been partial to Old Florida 4a in the Florida Keys. It is an entire alignment of the original Overseas Highway before US 1 that very few people even know still exists...or existed.
The old Reedy Creek Causeway in rural Osceola County. Before the current US 17 & 92 bridge over the same creek, both routes used that which is now abandoned. I believe its closed off, but FDOT left the bridges and islands in between them probably cause there was nothing in the budget for removal when FDOT built the existing crossing.

And just west of there the brick alignment of Old Tampa Highway is ironically still in use...go figure.
We have an unused ramp (only used when main ramp is closed for construction) from eastbound 401 to northbound 400.

That's a good question. Most likely it would have transitioned to an at-grade arterial, but I don't know for sure. I do know the routing north of here would have mostly followed a nearby railway.
There is one, if not two, stretches of former IN-63 that have since been bypassed in the Newport, Indiana area, and, although they're not completely unused, they don't see any traffic other than local traffic nowadays.
The first stretch (which I'm not sure if it ever was IN-63 at any point) is the main north-south street in Newport, which includes a bridge over the Little Vermilion River at the north end of Newport and a large hill at the south end of Newport, and it isn't exactly unused: in addition to being a local street, it is used for an antique car hill climb race every fall! If the first stretch was ever IN-63 (Google Maps lists a very short section of roadway at the southern end of the first stretch as the misnamed "S Old Ushwy 63" (https://www.google.com/maps/@39.8750733,-87.4076339,16z)), it was probably bypassed by the second stretch that I'll discuss in the next paragraph many years before IN-63 north of Terre Haute became a divided highway in the 1970's.
The second stretch of former IN-63 in the Newport area, which was IN-63 prior to IN-63 becoming a divided highway north of Terre Haute, is the original IN-63 bypass around Newport, and it is a narrow two-lane road around the west side of Newport immediately east of the current IN-63. This stretch isn't completely unused (although the northern half of it probably doesn't see more than a few cars per day traveling on it under normal circumstances), as it serves a couple of residential properties as well as traffic turning off of current IN-63 from the south to go down the hill into Newport.

How many abandoned miles of the Will Rogers Turnpike are there?
During the trip from Oregon to Memphis TN, I saw an old US 66 expressway section that was in the countryside approaching a town that were only used by a tiny handful of homes out there. It's the perfect place to go tell your kids to play in the middle of the highway!

I was always fascinated by the old road through the Old Faithful area of Yellowstone National Park that was eventually bypassed in either the late 60's / Early 70's (can't recall when.)
It's now used as a trail.

Top Left: I-84/CT 9 interchange in Farmington. Half of the ramps are used. Was supposed to be an interchange between I-84 and the unfinished I-291 beltway. You can see the continuation of the highway in the median of the in-use portions of the north end of CT 9, and the extension of roadway to Middle Rd.
Top right: I-91 in Rocky Hill at what would have been the southern terminus of the I-291 beltway. Part of the ghost roadway exists. Until about 15 years ago, usused bridges existed that were removed to widen I-91 in the area.
Bottom: Southern end of CT 11. Note the bridge over CT 82 and a portion of the road extending southeast into the woods before ending. Part of the now-cancelled CT 11 expressway to the I-95/I-395 interchange in Waterford.
In PA, near Tobyhana the old US 611 is next to I-380, but is not open to the public. This is why the part out of Scranton is signed PA 435 instead of PA 611 due to its separation from the downgraded route number

The end of US 6 in Provincetown, MA, used to be four-laned all the way to Province Lands Road until 2009 when it was tapered off to just two. MassHighway NPS (northern end is on Federal land) didn't bother to remove the pavement from the now unused carriageway.

The New Jersey Turnpike has a short stretch of abandoned carriageway adjacent to the Joyce Kilmer Service Area. It's left over from when the "dual-dual" configuration was extended south from Exit 9 to Exit 8A; the old northbound carriageway was severed, and abandoned, in order to make room for the ramps connecting the northbound inner roadway to the service area. In the map link below, it's the second carriageway from the right (on my screen, it's just to the left of the beginning of the word "Sunoco").

They rotate what US 23 uses every once in a while. It's a pavement test section. When I was last through there in 2006, both main carriageways were not using the center.
Part of the old southbound carriageway of I-75/85 just south of where the two routes merge is still intact, now forming the median between the two sides. Four lanes, including two HOV lanes, can be seen in the satellite imagery here (https://www.google.com/maps/@33.7889749,-84.3913421,124m/data=!3m1!1e3).

Staten Island had a major expressway get canceled and NYSDOT R10 built any and all planned ramps instead of doing "ghost ramps". Actually used to be worse: the interchange at the east end of the Richmond Parkway was built, but removed when they widened the SIE.

That's because of the removal of the Cline AVE bridge, right?
Yes, though that doesn't necessarily explain why the remaining section is used Westbound but not Eastbound. I wasn't living in this area when the bridge was shut down and then removed, so I don't know everything that went on, but the result is very odd that you can drive just one way on perfectly fine two way stretch of road.

If I lived closer, such as Philly-based Roadgeek2500 does, I'd go take a look myself and report back. Since the new roadways aren't yet in use, and won't be until a subsequent project to add more ramps (scheduled to START in 2019) is completed, I would count this as a currently unused stretch of highway, meeting the "etc" portion of the OP.

Tell us more about this I-70 Breezewood thing which you reference (JK; please don't). I like the abandoned Laurel Hill Tunnel in western PA; because the OP asked "and why?", I'll go with "because it was originally built as a train tunnel, and has been repurposed for high speed race car aerodynamic testing".
My favorite is the western portion of I-189 in Burlington, VT. Because the OP asked "and why?", I'll go with "because I like its collection of unused ramps and the curve in the unused portion".
My favorite is the abandoned section of the Pennsylvania Turnpike. I like the tunnels (Rays Hill and Sideling Hill). The other abandoned section of the Turnpike features the bypassed Laurel Hill Tunnel as well. You can see the western end of the Laurel Hill Tunnel traveling eastbound at milemarker 99.

Looks like AL started work on these projects then gave up when the money ran out (or when they diverted money to more pressing projects)
US 50 between Lawrenceville, IL, and Xenia, IL. Nearly the whole 50 miles has some form of frontage road or abandoned pavement that used to be US 50. Most of this is still in use as frontage road or IL 250, but the stretch just east of Clay City has a few ancient bridges that have piqued my interest.
Bridge 1: https://goo.gl/maps/tfENATYnZU42 note the brick guardrails.

There is also an abandoned rest stop in the area.

And here's PA 63 at US 1, you can see the ROW for the unbuilt expressway to the northwest.

If I'm not mistaken it's open to traffic all the way to the dead end, so it's not "unused"
Here's a stub at the southern end of NJ 18 complete with a ramp from NJ 34

It's fenced off, but still appears to be used by the DOT
It's not being used for it's intended purpose. The part past Evans street is not a highway, more like a driveway.
Here's another one I passed recently: the old Mogantown interchange on the Pennsylvania Turnpike. It was decommissioned after I-176 was rerouted to make a direct connection to the Turnpike.
