No that's the cheap easy retard solution for retarded Americans, but it's better than nothing.
For something that resembles proper road design, you should first get a central reservation (or "median"). Maybe put some trees on it, would make the whole thing look a big less ugly too.
Now that you have a central reservation you don't have to turn left across four lanes anymore, because traffic only goes in one direction, divided by the median. Let's say two lanes per direction, since the road is five lanes wide at the moment that's easily achievable. The amount of traffic doesn't look at all high enough to warrant four lanes, really looks like you could just have two or at most three lanes with no discernible difference in traveling speeds and spend those taxes elsewhere, but let's ignore that for now.
So by now you've eliminated all frontal and most side impact collisions. Good job! But I know what you're thinking:>"But what if I need to go left?"
That's where the roundabouts come into play. You simply place those roughly every half mile at existing intersections, and then people can use those to change direction. You might have to drive a small detour but you save that time by not having to wait minutes for an opening in traffic when turning left.
Then you can go on to fix other things. For example, they seem to have completely forgotten the pedestrian crossings? Like if people who live in those houses want to eat some Red Lobster across the street they're supposed to cold start their car to drive 50 yards? Really not sure what the thinking was here. But don't worry, because with a central reservation it now even becomes possible to walk across a four lane road, since you have a place to stop in the middle.
There you go, fixed your shithole.
