V2 – Underground Highway X intersection
Underground Highway X intersection V2 (underground roundabout) at level -2 & -3, allowing metro, train & paths at level -1.
– Have some weaving with roundabout jonctions
– Flattened terrain is highly recommended when using underground intersections, it hardly work well with hills.
– Rebuilding some segment could sometime be painfull (especially when for some reason it sometime modify the terrain and underground aspect of the said segment) , click wisely when connecting, removing some part.
