Ok, I assumed what I wrote after Tom had written that "trucks are stuck with alternates that are slow, circuitous, congested, and/or relatively unsafe".

Kind of - the Saw Mill River Parkway doesn't have driveways, but it has some side streets and stoplights, even though most of it is accessed controlled.

In Boston a parkway is generally a divided highway but not limited access. Sometimes not even divided (ie Mystic Valley) but generally multi-lane.

I wonder if the word parkway derives from the fact that most of them have a median that is usually greenspace.

Bleh. Those East Coast parkways look nice. We here in Fond Du Lac only have the Ducharme Parkway, a little two lane street that passes some UWFDL(University of Wisconsin- Fond Du Lac) owned natural area. woooOOOoo.

Its not just Georgia, in California, Parkways are usually wide avenues that cut through some suburban city, not the freeway things in the East Coast.

Georgia is certainly not the only place where use of the "parkway" designation isn't regulated and can be used for naming roadways of various quality. I have seen parkways all over the U.S. that turned out to be just a plain city street.

In Atlanta, there were a couple of streets that were so rough and decadent that the street name became synonomous with danger, crime, drugs and/or prostitution - Stuart Avenue and Bankhead Highway. In an effort to revitalize the areas and mask the attached name stigma, Stuart Ave was renamed Metropolitan Parkway and Bankhead Hwy was renamed Donald Lee Hollowell Parkway.

Neither is anywhere near what someone would imagine a parkway to look like, but I'm sure there are other cases of cities doing this for the same reason.

Thanks for the explanation Georgia is the only state that I've been to where it really took my attention.

Someone probably got a brainwave, created this, and showed us how the A2 near Abcoude will look like in 2040

My understanding is that not only the median but the expanses on either side would be wooded or park-maintained in order for it to be a canonical "parkway"... part park, part highway.

Of course, as we see in Georgia, the intent can be stretched in practice. Even in metro New York, some of the parkways are fairly, um, developed and the views aren't quite so bucolic as we might see on the Palisades, the Taconic, or the Merritt. The main differentiation for parkways in metro NYC seems to be that trucks and/or lorries aren't allowed on them-- they need to use the so-called Expressways.

21 lanes, and traffic is still heavy.

What tram at the Getty Centre? There's the thing they call a tram but that isn't it.

What I don't get with Interstates is how they didn't realise that the NE would need more numbers than what was assigned. I-45 was a mistake to number it that, as was I-70, which is about halfway down the country west of St Louis and about 60% of the way up from Indianapolis. Unfortunately both US 50 and US 60 run through Missouri, so either of those numbers are out due to the rules.

What would have worked better would be to have somewhere Central, like St Louis, as the start point. That way there'd be no US/I number conflicts in the middle of the country and numbers wouldn't need to be deleted (save maybe on opposite coasts), nor out of place

I-0x: 33% (4, 5, 8) not helped by I-10 being close to the coast/border.
I-1x: 60% (0, 2, 5, 6, 7, 9)
I-2x: 60% (0, 2, 4, 5, 6, 7)
I-3x: 40% (0, 5, 7, 9) not helped by I-45 being so close to I-35, nor I-30 being close between I-20 and I-40
I-4x: 50% (0, 3, 4, 5, 9)
I-5x: 30% (5, 7, 9) US route conflicts - note no even numbers
I-6x: 50% (4, 5, 6, 8, 9)
I-7x: 110% (0, 1, 2, 3, 4, 5, 6, 6, 7, 8, 9) - note not counting I-74 twice
I-8x: 130% (0, 1, 2, 3, 4, 4, 5, 6, 6, 7, 8, 8, 9)
I-9x: 80% (0, 1, 3, 4, 5, 6, 7, 9)

As you can see, there's a clumping in the I-70 to I-99 range leaving only 2 numbers spare (92, 98) and having 4 duplicates. Clearly there should have been a bit better distribution of numbers so that this didn't happen. OK, part of the problem is lots of one-state interstates in this grouping (both I-88s for instance, and ignoring a few miles, the I-86s and I-76s). The US routes/Interstates can't have the the same number in the same state rule is part of the problem, and also rather excessive, given many countries' habit of having motorway and national road going along the same corridor with the same number.

What about Interstate 74 and U.S 74? Don't they share the same pavement somewhere?

They do now, where I-74 is south of I-40. It seems rather silly that both I-73 and I-74 have to have lots of shared sections and diverge lots. As I-74 in Virginia is I-77, it seems odd that I-74 in NC and SC couldn't be I-3x, or make US 74 in NC (which is becoming freeway east of I-26) I-28 and the I-77 to I-73 section of I-74 a 3-digit number.
