Elevated Highway to Roundabout Exit
This is a simple exit for an elevated highway (lvl +1) that leads directly to a 3 lane roundabout.
25’460 to build, 292 / week maintenance
The gap between the highway lanes is wide enough to place a train track in between (see pictures 2 and 3), but you’ll need some danny’s no pillars mod to do so:
