Parallel freeways

[MrDisco99]

Examples of parallel freeways that are close enough to serve essentially complimentary (or redundant) traffic, but one provides more local access or toll vs. shunpike or trucks allowed vs. cars only, etc... bonus if they weave...

I-295 and NJTP

Saw Mill Pkwy and NYST (I-87) through Westchester

Hutchison and Merritt Pkwy's and I-95... could extend this down to Whitestone and Throgs Neck Bridges and Belt Pkwy and I-295

LIE (I-495) and GCP/NSP through Queens/Nassau County

Seems these are mostly in the northeast.  What is it about highway policy in that part of the country that has caused these to pop up there?

Here's one outside the northeast... Florida's Turnpike and I-95 south of Port St. Lucie

In the San Francisco Bay Area, 880 and 580.  580 is cars only.

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!

Wantagh Parkway and Meadowbrook Parkway in Nassau County
Southern State Parkway and NY 27 in western Suffolk County
I-87 and the Harlem River Drive/FDR Drive
I-87 and Taconic Parkway
Add I-678 to the list of Belt Parkway and I-295.
US Route 3 and I-93 in Massachusetts and New Hampshire
I-93 and I-95 in Massachusetts
Bluegrass Parkway and I-64 in Kentucky to an extent
I-55 and I-57 in Missouri and Illinois
I-41 and I-43 in Wisconsin.
Pretty much all of Dallas and Fort Worth. Too many examples in that one area.

I know I keep modifying this, but I keep finding more and more examples one by one.

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.

[hotdogPi]

I-190 (NY) and QEW (international border)

[doorknob60]

In the San Francisco Bay Area, 880 and 580.  580 is cars only.

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-80 and I-88 in Illinois for Chicago-bound traffic from the Quad Cities or farther west.

[kendancy66]

I-10 and CA-60 from East Los Angeles to Beaumont, CA

[Max Rockatansky]

Didn't see I-15 and the car only UT 67/Legacy Parkway anywhere in the previous posts near Salt Lake City.

Good call. I remember a fantastically parallel road somewhere here out west, but I couldn't remember where.

I-70 and US-6/6th Avenue between downtown Denver and Golden.

[vtk]

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?

[Max Rockatansky]

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.


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).

I-75/85 and GA 13

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.

[KEVIN_224]

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.
