Perché questa strada è progettata in questo modo? Provenendo dal lato sinistro dello schermo, le due corsie si uniscono nella stessa corsia, quindi perché non un’unica strada? Perché dividerlo? Qualche ingegnere civile vuole spiegare?

Not really sure but could be that in the past too many cars pilled up at this intersection so they built a second road to have more leeway in the back.
The left lane becomes a completely new lane which means anyone on the left lane can proceed without stopping.
The right lane (or rather the middle lane, if we also count the third lane that turns to the bottom right) however merges with the existing lane, which means anyone on the right lane has to give way to traffic coming from the bottom right.
Because of this, there‘s a danger of people on the right (middle) lane trying to switch to the left lane (where they would be free to drive on) as soon as they notice that there‘s traffic from the right. This creates a high danger of conflict with traffic that is already on the left lane: The driver who just has looked intensively to the right and slightly back and who just noticed the traffic there then would have to safely look behind himself on the left to be sure that the left lane is free. His head would essentially have to be on a swivel for this. There‘s a good chance to overlook something in such a situation where you have to keep traffic behind you both on the right and left in view. Especially for the type of driver who is so impatient to begin with, that they want to switch to the left lane without stopping as soon as they see that traffic from the right will impede them.
To make this switch to the left lane impossible, the lanes are actually split so that no crossing is possible. Either the driver knows this beforehand and keeps on the left from the start, or they are forced into the wait-for-traffic-from-the-right behavior without having a chance to switch to the left.
