Thoughts on this unconventional motorway exit/intersection?

Posted by MisterBean on 8 February 2019 in English (English)

I have made an unconventional motorway intersection south of Gandazoara City, where the major route going from the capital to the northern border of Rhododactylia crosses the southern artery of the city. At the crossing, said artery turns from a country road to a grade-separated highway.

The roads cross two times, allowing for the exits to be separated according to the desired direction.

What do you think?

Why not doing so? But some of your ramps are too short. Only 40 m to the next level? A rough step

It's probably better to have the roads meeting at a less oblique angle. It'll make more sense to have a single motorway junction for all directions, and then a simple, unconnected flyover for the other intersection.

One would say yes, the other one would say no. I second Histor that the ramps are too short, the minimal lenght should be ~200 meters to change from one level to another. The idea of connection between the two roads using their position relative to each other is good idea, cheap idea. In countries like Russia or Poland you may find many junctions like that.

Assuming the Southern Connector pre-dates your North Motorway, you should have some sort of geographic constraint to the west of the Southern Connector (some small buildings, a forest, a water feature, whatever) to help justify why the motorway crosses over the minor road twice. Motorway bridges are expensive so the original engineers probably would’ve routed the motorway to stay west of the minor road unless there was some decent reason why they couldn’t.
