Do you think WA-167 (the Valley Fwy) and I-5 would count? Between Olympia and Bellevue, 167/512 is only about 4 minutes slower than 5.
I always thought it was weird how close I-81 and I-476 are in the Scranton/Wilkes-Barre area. In the Utica area, NY 49 and I-790 straddle I-90 for a few miles. North of Binghamton, I-81 is on the west side of the Chenango River, and the NY 7 freeway is on the east side.
VA-267 (toll freeway) and the Dulles Access Road in its median (non-tolled but access only to/from Dulles Airport) west of Washington DC.
Westernmost section of the Herb Gray Parkway (Highway 401 extension) and the E.C. Row Expressway in Windsor, Ontario. A very short stretch, but per the OP there's a bonus for weaving!

They don't weave, but FL-618/US-92 and I-4/I-275 in the Tampa area might qualify.
Near Miami, you have FL-826 and the Homestead Extension, although the latter seems to carry plenty of local traffic and I believe there was talk of HO/T lanes.

I'll throw in I-280 and US-101. At parts they have some distance between them, but at other parts they are very close. Also they weave (once) in SF. Throw in the fact that they both travel from SF to San Jose, directly meeting each other twice near/at each end, I think it counts.

I-95 and I-895 through the Baltimore area
I-95 and I-495 through Wilmington
I-70 and US-6/6th Avenue between downtown Denver and Golden.
I-71 and I-75 are reasonable alternates to each other between downtown Cincinnati and Mason, Ohio.
For that matter, I-75, I-675, and I-70 form a fairly reasonable alternate path from Cincinnati to Columbus. Several minutes longer, heavier traffic, but (currently) smoother pavement...
Edit: How in the world did I forget OH 315 and I-71 on the north side of Columbus?
Now that I think about it wouldn't I-10 and I-17 in downtown Phoenix more or less count? One that certainly would be AZ 143 and what was AZ 153 which were built as parallel freeways in mind east of Sky Harbor. Basically AZ 153 was turned back over to the city of Phoenix as an extension of 44th street but it is still 2 miles of expressway within direct sight of AZ 143 and even has a ramp for Sky Harbor.
Spain built several toll-free autovías next to tolled autopistas, both are freeway-type roads with a 120 km/h (75 mph) speed limit.
An example is AP-7 and A-7 in southern Catalonia.
(https://www.aaroads.com/forum/proxy.php?request=http%3A%2F%2Fi.imgur.com%2Fjb9ObE5.png&hash=6476cd603f44029b5740c271a090a5d641984413)
There are quite a number of these, for example AP-7 and A-7/CV-10 north of Valencia, AP-68 / A-68 west of Zaragoza, A-7 and AP-7 in the Marbella area, AP-7 and A-38 between Valencia and Alicante, AP-7 and A-2 near Girona, AP-46 and A-45 north of Málaga, the radial toll routes into Madrid, etc.
And then there are many toll roads which have toll-free alternate routes for long distance traffic. For example from Valencia to Alicante the traditional route was AP-7, a toll road, but you can also take A-7 which runs farther inland, and even A-31 and A-35, which is also an inland route, in addition to the incomplete A-38, which runs right next to AP-7.
From Barcelona to Lleida the toll road is AP-2, yet traffic can take the toll-free A-2 which runs a little farther north. From Girona to Lleida, the traditional quickest route was AP-7 and AP-2 / A-2, which is mostly tolled, but they expanded C-25 into a freeway which is a shorter route.
The traditional route from Madrid to Toledo is A-42, but they also built AP-41, a toll road which is severely underused (1,000 vehicles per day). Spain has a number of bankrupt toll roads, in particular those built after 2000. The older toll roads appear more viable despite the low traffic volumes.
In Detroit, you have M-8 and I-94 between I-75 and M-10. and to add, I-96, M-10 and I-75 (chrysler) between I-94 and I-75 (Fisher).

There are two spots along I-91 where CT 15 is right smack next to it. Near Meridian, I-91 is in the median of CT 15. Near Hartford, I think its either the other way around or the same situation. Nonetheless at two points the carriageways get braided.
Before I continue...it's MERIDEN. Moving on...
Actually CT Route 15 flanks I-91 for that short stretch. Heading north, from left to right on the map:
|| 15 S | 91 S || 91 N | 15 N ||
It's not really the same set-up in Hartford, but they are braided a bit with the exit ramps to each other. It's immediately south of the Charter Oak Bridge. The bridge carries US 5 and CT 15. US 5 splits off once away from the bridge. CT 15 goes for another half mile or so and then merges with I-84 at Exit 57.
The one that glares most at me is also 'across the pond', A5 and A67 between Darmstadt and Mannheim in Germany, with provisions to continue A5 northward (there is an unbuilt gap in A5 in the Darmstadt area that would feed it into A661) to Frankfurt am Main.

OH 2 and the Ohio Turnpike in North Central Ohio & OH 2 and I-90 east of Cleveland
I-76 and US 30 in PA (where 30 has 2 freeway segments)
I would add in I-290 (Ike) and I-294 (Tri-State) in the Chicago western suburbs for about 3 miles. Generally, the two roads go to different places, but these roads are parallel and right next to each other between North Avenue and the Hillside Strangler.
- I-684 and the Taconic in Westchester and Putnam. You could throw in NY 9A/US 9 and the Palisades Parkway as well.
- SOB and Wantagh Parkway in Nassau Couny
- Garden State Parkway and NJ 21/17 in North Jersey
- I-70 and Ohio SRs 161/37/16 east of Columbus
- I-87 and the Taconic in the Hudson Valley. Never more than 20 miles apart, but on opposite sides of the river.
Several examples in the south:
- I-40 and US 70 in Arkansas
- I-55 and US 51 in Mississippi
- I-59 and US in Louisiana, Mississippi and Alabama
- I-10 and US 90 along the Mississippi Gulf Coast

You can even add I-95 into the mix here, as all 3 serve North-South traffic, and are no more than about 10-15 miles apart at most. Heck, I-95 parallels itself for the time being as both the NJ Turnpike (I-95) from approximately Exit 6 to Exit 8 is parallel with legacy I-95 in PA in the same area.

They should count. Many are circles or semicircles, which do not parallel.
Yeah, not all x95s are beltways. 895 is 100% parallel and not remotely circular. 495 is a bypass of downtown for through traffic. 295 is a fully parallel route on the other side of the river, connecting the Delaware Memorial Bridge to Camden and Trenton, never intended to be anything remotely resembling a beltway until the Somerset Freeway was cancelled.
As for the Wantagh and NY 135, the Meadowbrook has always struck me as a counterpart to the Wantagh.
Some other California examples:
Route 99 and I-5 between Route 120 in Lathrop/Manteca and US 50 in Sacramento
Route 170/US 101 (Hollywood Freeway, northern segment of Santa Ana Freeway) and I-5 (Golden State Freeway) between the San Fernando Valley and the East Los Angeles Interchange
I-5 and I-805 in San Diego
Would Route 163 and I-15/Route 15 in San Diego count?
Minor examples in the San Diego area:
Friars Road expressway and I-8
Pacific Highway (old US 101) and I-5
Kearny Villa Road (old US 395/I-15) and I-15 through Miramar MCAS
Fairmount Avenue Expressway (old US 395) and Route 15
I think you took "loop" a little too literally. The FHWA refers to 3dis as "circumferential, belt, or loop and spur routes" ( http://www.fhwa.dot.gov/planning/national_highway_system/interstate_highway_system/routefinder/index.cfm ). Heck, even our well respected Kurumi uses loop in the sense I was referring to! ( http://www.kurumi.com/roads/3di/ )
Now that we got semantics out of the way, most 3 digit routes with even numbers are generally going to connect with their parent highway on both ends. Using NJ's I-295 for example, it was going to parallel I-95 in PA and still does; the routes are no more than 10 miles away from each other and can serve the basic needs of many drivers traveling thru the area. I-895 meets up with I-95 on both ends in Baltimore. Thus, most 3dis will meet up with the parent twice. And doing so, unless it takes a long, windy route out of the way, those 3 dis generally parallel the parent, which is why there's no point in listing a 3di as a parallel route to its parent 2di.
Yes, there's some outliers, such as I-476 in PA, which in true form should've been an I-x95 or even an I-x81...and an odd numbered one at that since it spurs away from the main highway, never to return.
I-94 and WI-16 in western Waukesha County.

- I-59 and US in Louisiana, Mississippi and Alabama
- I-10 and US 90 along the Mississippi Gulf Coast
- I-20 and US 80 in Mississippi
Virtually none of your US highway examples are actually freeways for any of their length - there's a short US 70 freeway section around Hot Springs that's nowhere near I-40 in Arkansas, and there's a couple of miles of US 51 freeway in Jackson MS, but that's about it.
Pulaski Skyway and I-78/Newark Bay Extension. They both serve the same basic area, both feed to the holland tunnel.
In Westchester County, NY you have the Taconic Parkway and NY 9A both parallel each other where the short stretch of NY 9A is freeway and of course at that point the Taconic is full freeway as its south of the Reservoir Bridge where there are no at grades there.
Re the I-10/CA 60 parallel cited previously, I'd make that a triple parallel, with CA 134/I-210/CA 210 as the third facility. Some might even suggest a 4th: CA 91 -- but since that freeway essentially empties out on 91 or 215 well west of the end of other routes, I'd at best consider the addition of 91 to this grouping to bring it up to a "3 1/2 facility" status.

Part of the problem with this thread is the lack of definition of parallel. Yes, those roads are parallel, but they are largely far enough apart from each other to make a proper grid of expressways.
True....but in this instance, there is a commonality of overall purpose to these routes -- connection between the "traditional" population/commercial center of the L. A. basin and what is locally termed the "Inland Empire", generally considered to be the western part of San Bernardino and Riverside counties -- and the locale of much of the housing development of the early 2000's. I lived in Redlands and worked in Ontario from 2003 to 2009 and can attest to a definite synergy between the routes. In 2007 when 210 was fully completed from 15 to 215, peak-hour traffic on 10 between those points lessened about 20-25%; but by mid-2008 it had returned to its usual LOS "D" or "F" levels, while 210 was experiencing daily stop-go congestion west of 15 as soon as the extension to 215 opened. The last time I used those facilities on a regular basis (2012) before moving up to the Bay Area, both 10 and 60 eastbound featured massive congestion starting at a little before 3 p.m. with no letup until about 7:30; 210's congestion level is a little more forgiving (likely a hard "D" LOS), but it starts all the way back on the I-210 segment at or near the I-605 junction and doesn't subside until well past I-15, with the most difficult sections immediately east of CA 57 and then through Claremont and Upland. None of this is particularly surprising or unexpected; the massive pre-recession "infill" development in the virtually uninterrupted mass of housing that is Rancho Cucamonga, Fontana, and Rialto is having the effect one would expect on all three freeways forming this triplicate facility -- you build it, and they will need a way to come!
The Philippines prior to the late 1990s had no examples of parallel limited access roads, with SLEX and NLEX both radiating away from EDSA for the most part (NLEX directly ending at EDSA, SLEX ending just north of it depending on if the Buendia Flyover counts as part of the road).
1999-present, the first two stages of the Metro Manila Skyway essentially served as an express route above SLEX, originally from Buendia Avenue in Makati to the Bicutan area, and eventually to the Alabang district in Muntinlupa.
With the 2020 opening of Skyway Stage 3, the Skyway now also has a segment parallel to NLEX (running in NLEX's median), between the Balintawak Cloverleaf (NLEX at EDSA) in Quezon City and the NLEX Libis Baesa exit in Caloocan.
In the future (if built), the Port Link Expressway along the Roxas corridor will be parallel to the Skyway, but to the west. The under-construction NLEX Connector, part of an urban loop with the existing NLEX Harbor Link, could easily be seen as a parallel route to the Skyway-NLEX corridor.

Some other California thoughts:
- I-880 and I-680 between San Jose and Route 262. Had the Route 238 freeway been built between Castro Valley/I-580 and I-680, it would have extended this parallel corridor north to link with the MacArthur Freeway portion of 580.
- Route 87 and US 101 in San Jose
- I-105 and Route 91 in the southern suburbs of Los Angeles County
- Route 55 and Route 57 in Orange County between I-5 and Route 91
- I-405 and Route 170 between I-5 and US 101 in the San Fernando Valley
- I-8 and Route 94 from I-5 in San Diego east towards Route 125
- Route 125 and I-5 and I-805 from Route 54 south towards Route 905
