Smart people who designed Interstates to reach the center of town.
I think that the ring road system is better because it doesn't get too crowded during rush hours. However, with American suburban planning, ring roads would get too crowded even if they didn't run through the city centre.

Sadly my town of Austin doesn't have a "ring" road. San Antonio and Houston have a good ring road system with Interstate 610 and Beltway 8 in Houston and Interstate 410 and State Loop 1604 in San Antonio. I've seen all four of those roads get crowded but 410 is a great bypass when you don't want to go through the city to avoid traffic.

And in so doing has cut off neighborhoods that used to be connected. I wished they hadn't planned Interstates that way.

I'm not sure that's possible. Unless the traffic on this road is literally bumper to bumper 24 hours a day, I fail to see how this can be.


You have been throwing around a lot of crazy numbers for NL motorways in a couple of threads - I'm not sure if they are really that accurate. Have you got any sources for these numbers?

Anyway, to the haters of the US Interstate system: Yes, the system is far from perfect, but it is the most impressive road system in human existance. What ever you say about it, and about the state of the roads/design of the system, it is an incredible piece of infrastructure and should be respected. No other country in the world comes close to the completeness of the Ixx system, and I for one am very, very impressed by it.

It's impressive road system in term of size (lenght) but not really quality.
Every hour after Minneapolis bridge collapsed more and more news emerges about poor condition of USA bridges.
In inspection 2 years ago this bridge got 50 points on scale from 0 to 120.
It didn't required immediate closure.
Problem is that 40% of US bridges have similar score.
Should drivers start to be worry while crossing bridges?

I can’t really imagine similar problem with German autobahns of French autorutes

USA build great system but have problem with maintenance. They pay low taxes so have low spending on maintenance
Problem is how to improve situation in country where nobody want to pay taxes high enough to do so

By the way, China will soon have system even longer than interstate

The researches found capacity for a highway is 2,200 veh/hr/ln.
So if the ADT is 120,000 for a 4-lane highway, which means it has to be 14 hours of smooth traffic continuously moving at 55mph or above. What do you think?

The 2,200 veh/hr/ln number comes from the US Highway Capacity Manual written by the Transportation Research Board. It's the basic guideline of highway design. I can't find it online, but you may find a hard one in the library.

California highway bridges are probably the most well maintained in the country, we've learned many lessons from pancaking overpasses resulting from earthquakes.

That´s correct, and also the number the Dutch government is working with. That guidance is pretty much used in the Netherlands too.

In tunnels, and also on bridges, capacity is lower. In the Netherlands, there are a lot of tunnels and bridges, and we see traffic jams occurring when intensity is over 1400 veh/hr/ln.

China's freeways are all toll roads. That's the difference. The vast majority of the US Interstate System are free to use.

The majority of individual Toll Roads in the USA(measuring by total toll roads, not by mileage) may be built to freeway standards, but they do not carry an Interstate designation.

There are numbers of interstates are toll roads. Here is a few of them:
I-95 NJ Turnpike, I-90 MassPike, I-87/90 NY Thruway, I-4 in FL, I-275 in FL

Reread the statement I made. I purposely said it that way because I knew you'd say what you said. I covered my bases there. Btw I-4 and I-275 are toll bridges. Not the same as toll roads.

Yes I know, once again reread what I wrote:

the pavement quality leaveaves a lot to be desired, but i must admit the sheer mass of the interstate system is just... amazing. not all things suck about the interstates... those interchanges are pretty great i must admit.

Can you show us some pics of a parkway? I saw them on the map in New York too (Bronx, Yonkers).

In California, parkway is another word for street.

I mean that i think in California, a parkway means a street, where you can park your along it?

But this is what wikipedia says;

In the USA, Parkways are defined as follows:

1. A type of road
1. A broad landscaped thoroughfare; especially : one from which trucks and other heavy vehicles are excluded[1].
2. A roadway in a park : a landscaped thoroughfare connecting parks
3. An expressway located on a strip of land legally constituting a public park and therefore not open to heavy vehicles[1]
2. A landscaped strip of land paralleling or running in the center of a thoroughfare


Parkway in Salinas, CA.
