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.
