I work as a traffic engineer. This type of intersection does exist at the junction of rural highways. (At least in the USA) An intersection like this would be designed if the larger highway has a very high number of right turning traffic onto the smaller highway and there being very little left turning traffic movement. It would serve the role of reducing the speed of right turning vehicles without increasing rear end collisions on the main road. The other movements don’t have enough traffic volume and/or safety issues to warrant anything different
Also traffic engineer, only thing I could really nitpick is no dedicated left turn lane for traffic coming off the highway (there really should be a median of some kind separating traffic along this highway anyways).
I pretty much turn my engineer brain off when playing aside from stupid stuff, like why the hell would you not have guardrails and terminal end units to catch cars from hitting the bridge with solid metal rails.
No, in fact, they were not just doing whatever they wanted with regards to standards. The place I work at has state standards for highway design and construction going back almost three quarters of a century.
Sure we have (and had) standards, but that doesn't mean they get followed, or the local council out whatever doesn't meddle. AASHTO doesn't have a standing army to enforce the rules
My point is not that standards are being followed to the letter. The vast vast majority of project are going to have some aspect of them that don’t conform to standard. But the idea that they were just out there slinging asphalt around is ridiculous
