This is at McGee and Bogard in Lewisville, Tx Appearently there was a street racing problem here, and several accidents at the T junction. The city first narrowed northbound traffic to one lane to prevent side-by-side driving, and to make it harder to turn left at a high rate of speed without stopping.
This latest measure of using temp barriers is rediculous. You can't see over them adaquatly at the stop sign.

If you can't see over a 30" barrier, you should not be driving.
I can see over them, but not well. They do hinder visability. I drive a Camry. They have to be higher than 30 inches, because they are higher than the bottom of my car window. A quick check of the website of the barricade company that these were purchased from shows that they sell these in 32 and 42 inch versions. I suspect that these are the 42-inchers. It was determined that standard height Jersey barriers cause visability problems at intersections, and thats why the low-profile square concrete barriers are often used on non-controlled access roadway work zones.
Think about this. If I can't see over them very well from my Camry, how is the driver of a Corvette going to be able to see over them at all. The driver's seat of a Corvette is much lower.
This is the view with the front of my car on the stop bar.

42 inches is a different animal from 30 inches, definitely. They should use the low-profile ones if the intent is to channelize, and not to protect anything.
I wonder how well a roundabout might work at this corner, although it might require adjusting the alignment of the two streets to avoid taking out any houses.
