It's going to take approximately 38 seconds from the time it opens until the time some dumbfrick makes a right turn on red into oncoming traffic at the crossover.

In east Tenneessee, the main exit on I-40 to the smokies was redesigned to be a double diamond. They never closed the exchange, but it was off season.

LINK shows the layout with arrows showing directions; you can click on the 'satellite' view to see it in real life.

Change orders, change orders, and more change orders. Drag your feet and try to skimp by with a skeleton crew, while you bid the job with twice the labor hours than you're using. Work slow as molasses during the mild weather months and fail to take advantage of said weather, and scramble because you didn't take into account that there will be bad weather for weeks at a time in the late spring, summer, and early fall.



So is this "affliction" something that affects only LA contractors? Because I've been in other states and they move MUCH FASTER when it comes to road construction.

Louisiana drivers are too stupid to figure out how to drive a roundabout. What makes anyone think that they could figure a diverging diamond intersection out?

I drove through one of these in Biloxi. It was my first time ever going through an intersection like that. It felt wrong driving on the wrong side of the road for a while.

A roundabout is more complicated, for at least the 5th time in this thread.

All you do is drive around the circle until you get to where you are wanting to go. If someone is too stupid to drive in a circle then they are too stupid to drive in a diamond. That stuff might work in other places but other places do not have the retard factor like Louisiana does. Hell the drivers in Louisiana are too stupid to figure out to drive on the basin bridge without causing a wreck and that is pretty much driving in a straight line.

One good wreck at the crisscross light and all lanes are fricked. It will happen...frequently.

It's the correct side of the road, treasonous colonial.

The ones on the north side of the city required a traffic cop to direct flow... for years! Hopefully that was only due to the amount of traffic not a design flaw.

You can’t change order a design/build project.

The contractor is also the designer. He can’t change order his mistakes.

At least not all lanes potentially blocked at one point.

Was it the exit just west of the I-110 exit?

I had to do a double take at that exit. Seems to work well here though.

There is a free right before the intersection, the same as current interstate ramps.
