The PA ring road and the expressway mainline were both at ground level, so the ring parapet stood INSIDE the carriageway (measured -10.0 studs of vertical overlap: a wall in the middle of the road). Reference photos of the real Daikoku Futo PA show the expressway flying OVER the parking apron on pillars, with the PA at ground level and ramps climbing up to meet it. Rebuilt to match: - mainline lifted 38 studs through the junction, eased in/out (max 5.26% grade, within real expressway limits) - PA ring + apron stay at ground level; legacy PARingPillar props removed - both on/off ramps regraded over the full rise with smoothstep easing, segments overlapped 3 studs so wheels can't catch a seam, plus support pillars and edge kerbs where the deck is high Verified in-engine against built parts (tools/diag_daikoku.luau), not just source: clearance now +28.0 studs, both ramps continuous (max step 5.62, no gaps). tools/plot_daikoku.py renders the plan/section for comparison.

Reports, for the stretch of mainline nearest the PA:
|
|
* the deck Y profile (is it flat? already climbing? in a tunnel?)
|
|
* which SIDE of the carriageway the PA sits on, per sample
|
|
* perpendicular distance from the mainline centreline to the PA centre
|
|
* terrain/ground height under the PA and under the mainline
