Especially on the edge- I think many states use a four inch width on regular two lane roads. Not the greatest thing, for sure- but not the end of the world either.

But people are not paying the actual cost of driving. Infrastructure is degrading quickly and something has to be done. Of course people don't want more taxes, but if they don't want more taxes, then they had better expect their government gifts to start dwindling.

Are you willing to build all of the new power plants and high-energy power lines needed to charge the batteries in a large national fleet of electric cars? Also, effective driving range has been a BIG issue for electric cars, with few ever being able to go more than 100-150 km between charges. Effective highway range on a full tank of fuel in my car is about 800 km.

Electric cars can go as far, that's really just a myth about them not having as long a range.

If electric cars are rolled out, let's be serious, it would be done gradually. That would give enough time for the power companies to match up with demand. I don't see why it shouldn't be done. Power companies will upgrade the infrastructure with respect to demand, and the rates will be higher for those who use the most. It's an experiment that definitely needs to be tried, especially in valley/desert cities.

I agree, but certainly not in the current status of the economy...plus the 47 billion dollars that are going overseas to who knows where...

I also noticed that many states only use Bots Dots as their primary lane marker. There's no paint. Once the dot breaks, it's gone so in some sections of I-90 in Washington, the lane markers are...not there. The new highways I see use 4-inch wide paint with painted rumblers. So the paint actually sticks out of the lane marker to form little bumps. Those are much more clear, but seriously, they are still thin. When it's raining, they're just invisible.

The best motorway marking I observed in Nevada - very thick and wide (~20cm). At the same time, it seems to me that Washington has a problem with road paint that doesn't stay on the pavement for too long. For instance, I-90 has some mountain stretches that don't have any lane marking at all, although the concrete pavement shows an obvious lane division. Also, they widened a highway between Pullman and Moscow right before the winter. Now, the winter is gone... and so is paint Well, maybe it was a temporary paint, I don't know since I am not a road engineer.

I know that's the case often in California and Texas, but I can't think of anywhere else where that's the case. I've never actually driven anywhere like that myself, so I have no idea how it works. It doesn't look great in pictures- but I've never been critical because I thought perhaps in practice it might work.

Some new Interstate highway photos, this time from Michigan:

I-696 (Michigan's Autobaun):





I-94:




I-475:


Myself and my co-webmaster Dan have been working a lot with Michigan photos lately on our website http://www.Canighways.com/MI/. There are lots of high-resolution photos of some of Michigan's large and interesting freeways. Please have a look at our site.

That's not true in Southern California.

But there are some places where the paint is completely worthless, like the East LA interchange. It's been painted and repainted so many times that it's hard to tell which ones you should follow. I guess it's a good thing that there's always traffic there.

Yeah that is true, I've seen some different types of markers used in Washington state, I don't know why they can't keep them consistent.

3 types off the top of my head:

1. Regular paint, often used with bots dots placed on it.
2. A very "glossy" sort of paint that has the painted rumblers. Those come off very easily, especially during winter.
3. Bots dots alone.

Yeah I can't either, most places use very nice paint, I don't get why many places don't. Bots Dots come off very quickly, especially with heavy truck traffic or winter weather. It's better to see where the lanes are rather than "feel" them. There's a section of State Route 520 that uses both bots dots, reflectors, AND glossy paint with painted rumblers.

Also what really bugs me is the way the paint is removed. Either they "rub" the paint off the road or the paint is so thick that over time it actually punches a hole into the pavement. Either way, once they remove the old paint, there's a very shallow hole (a few millimeters) that is in the place of the removed pavement markings.

Great report again (and yeah, I'm a slow coach too again ). I didn't know these railguards were intended for preventing suicides/murders. Actually, I was never thinking about it.

Yes I like those type of markings. The center dashed lines could be longer though. I don't know if there's a specific purpose to the spacing of the lines, but longer lines and wider spacing gives a calmer look haha, although that would probably lead to increased speeding...I know Washington state has glass beads in their paint to reflect light. I'm not sure if that's the case on the picture you sent me.

I also noticed how nicely colored European roads are. Roads in the U.S. seem to always have a very noticeable lighter color where the tires normally travel, does anyone have an explanation of that? Do Europeans use some coloring on their roads?

^ Here in Spain there are some light gray asphalts too (usually because it's old or it supports heavy traffic), but I've noticed (in photos) that your asphalt is lighter. I haven't seen any US photo with our typical black asphalt.

When I go shopping I don't want to have to carry all my belongings 2 miles from the train station when I get off and hope that no one steals my merchandise. It's much better to put that in your car, lock the doors and get back to your house in 10 minutes instead of 2 hours.

What's good for the environment is generally bad and very uncomfortable for humans. The environment might like it better if I walked from Miami to Tampa along Interstate 75 but the same environment might kill me. Mosquitoes, alligators, high heat, potential lightning strikes...etc will all attack you during the possible 6 day journey. Contrast putting a human in a car. Very comfortable, nice seats, a/c, relative safety from the weather and maybe a 2 hour trip is much better than walking.
Are you nuts? I am not talking about walking miles to and from a train station every day, nor am I talking about walking from Miami to Tampa. Keep creating those strawmen arguments. I guess you find it enjoyable to sit in endless traffic jams for hours and hours.

Acid rain, cancer, lead and mercury poisoning, toxic waste dumps, air and water pollution, those are things that are bad for both the environment AND humans. You see, humans need a clean environment as much as any other creature- we are organic organisms that still rely on clean air, water, and food to survive, all of which are not possible when we ignore the environment.
