In case you would like guidance: Your intersections are way too close to each other for the amount of traffic they’re seeing. The streets also seem to be unnecessarily wide. Wider streets make for bigger intersections, which take longer to cross and thus increase the amount of conflicting cars in the intersection.
The slope going up to / coming down from the bridge is literally the stuff of nightmares; I have a recurring one about going up a steep hill I can't see over, onto a bridge, and the hill is so steep on the other side that my vehicle starts falling instead of driving, and I know I'm going to crash.
The only nightmares I have are literally driving on a highway like this over the ocean. It always feels insane and I have no idea why I would be driving on something that insane until I randomly realize how ridiculous it all is and wake up in a cold sweat.
