Sister highways and twinned thoroughfares

In case you aren't aware, "sister cities" and "town twinning" is a program by which two cities agree to form a friendly relationship and exchange people, ideas, gifts, and other things. These relationships can be chosen based on shared characteristics, like population, industries, ethnic communities, histories, and cultures.

These kinds of relationships could easily be applied to highways, and can even overlap with their twin cities. It would be fun to assemble a few pairings from the collective knowledge of the forum, though I would caution that pairing freeways together because they happen to use the same layouts or interchange types would be too boring.

To get us started:

Washington State Route 526 and California State Route 14: Both highways pass through areas with close ties to the aviation and aerospace industry, and have appropriate names. WA 526 (the Boeing Freeway) runs through the main Boeing widebody factory that has long produced 747s, 767s, 777s, and (most) 787s. CA 14 is named the Aerospace Highway and travels close to Palmdale's aviation complex (which includes Boeing, NASA, and Northrop Grumman) and the National Test Pilot School. It also runs near the Mojave Air and Space Port, which is home to a massive plane graveyard that typically includes more than a few planes produced in Everett.

Another industry-related one: Washington State Route 520 and California State Route 82. Both highways traverse some of the most tech-heavy corridors in the United States, and perhaps the world. WA 520 connects Amazon HQ1 to Microsoft's headquarters and the offices of Nintendo of America, among others, in Redmond. CA 82 runs through most of Silicon Valley and passes near many of the famous suburban campuses for tech giants like Google, Apple, and Facebook.

Probably both US 6 in Cape Cod, Massachusetts and Interstate 485 in Long Island, New York. Both highways serventhe city to beach, US 6 - Boston and Providence, I-495 - New York, traffic and are both laid out in which depending on where one is traveling to, they would get off somewhere different from someone going farther down the island.

They aren't like other city-beach connectors, such as I-195 in New Jersey and I-264 in Virginia, in which everyone travels thrle full length of the highway to get to the beach.

Aren't Chicago's Dan Ryan Expressway (I-90/94 South of the Jane Byrne Circle Interchange) and Toronto's 401 Freeway formally known to be Siblings or Related?

CT 2 and the ACEX.  Both serve as a way from a city to casinos, and the beach (although they are separated by a few miles in the case of CT 2).
Interstates I've clinched: 97, 290 (MA), 291 (CT), 291 (MA), 293, 295 (DE-NJ-PA), 295 (RI-MA), 384, 391, 395 (CT-MA), 395 (MD), 495 (DE), 610 (LA), 684, 691, 695 (MD), 695 (NY), 795 (MD)

Triplets!  US 101 connects a trio of twinned cities with ports.  WA: Aberdeen, Hoquiam.  OR: Coos Bay, North Bend  CA: Eureka, Arcata.  None of these are major cities but they do represent the largest population for Washington's, Oregon's and rural Northern California's coast. 

As for the highways, US 12 comes into Aberdeen as a 4-lane expressway, where it intersects a 4-lane surface street 101.  Coos Bay-North Bend has 101 with two one-way grids combined with expressway.  6 miles south of Coos Bay, SR 42, which was originally 101, is 4-lane expressway as it heads to the county seat of Coquille.  Eureka and Arcata top the list.  101 from Arcata north is freeway, 101 from Eureka south is freeway, 101 is 4-lane surface street and one-way grid in Eureka with the section between Eureka and Arcata being expressway.  SR 299 is freeway heading east of Arcata. 

Grays Harbor, Coos Bay (the body of water, not the city) and Humboldt Bay are large in size.  Before the old growth timber bust took place in the late 70's, each port was known for having lots of ships coming and going to handle chips and logs.  Even though that industry is down considerably from its peak, these ports still have thriving fishing and crabbing industries.  Oysters are also part of the bay's aquaculture situation in Coos Bay-North Bend.  There are also some recreational boats in these harbors.  USCG facilities presence is strong as well.

Railroads: A landslide took out the line to Eureka/Arcata a long time ago.  CB-NB has a rail line which is not in that good a shape but it does manage to hang in there.  I do not know about Aberdeen/Hoquiam.

Airports: North Bend has scheduled airline service with levels of service varying according to the season.  Arcata has an airport with a lesser level of service than the one in North Bend.  I do not know the situation for Aberdeen/Hoquiam.

Climate conditions are pretty much the same for all three areas despite the distance between the northern and southern points being around 600 miles.  Temperate maritime with annual rainfall being around 60 inches and snow not being common shows the moderating influence of the Pacific Ocean.

For those who want a scenic drive, good food and cooler temps in the summer, you could do no better than to drive US 101 to explore all three twin port cities and the area in between.

US 101 is THE backbone of the Pacific coast from Bandon OR to Willits CA.  Industry, tourism and local traffic would be gone or severely crippled without it being in functioning condition in BOTH states.

Government would be tolerable if not for politicians and bureaucrats.

Not highways, per se, but the freeway systems of Atlanta and Los Angeles certainly qualify for this because they both have perpetual traffic jams.
Go Cubs Go! Go Cubs Go! Hey Chicago, what do you say? The Cubs are gonna win today!

I-76 Schuylkill Expressway to Philly, and I-376 Penn Lincoln Pkwy to Pittsburgh

Both branch off the PA Turnpike to reach the center of PA's two largest cities
Both are woefully congested
Both are some of the oldest freeways in PA, and still reflect the design standards from yesteryear
Both face geographical constraints
Both carry a segment of US 30

No, they did come about around the same time as early core-collector systems, but nowadays complex freeway systems are so common that's not relevant anymore.
and waterrrrrrr!
