Railroad Overpass

Crossing gates to slow??
Here's a vehicle overpass that will keep things moving quickly.
Large enough for two flat rail lines allowing for full speed trains.
Enough room between the rails for up to 18 belts/pipes or 12 and a service road.
Only Requires backfill. No excavators necessary!

Setup:
Shift click the blueprint in desired location to place retaining walls.
[Retaining Wall Short are required and must stay for this to work]
Backfill following photos on COI HUB.
Take the blueprint again, adjust down one level, and shift click it to place the bridge.

Tracks have to line up with the terraforming grid for this to work.
Enjoy faster vehicle and train traffic!!

Creator Note: This does not work with sandy backfill. I recommend slag, examples use slag.
