Bottom Exit Junction Offset Target

Gallery / Inter-section Routing

A bottom-exit junction fans to two targets in the row below: the section directly beneath it and one an extra column over, past an intervening box, entered on its left. The offset feed's horizontal leg would run straight through the intervening section at the target's station row; it detours through the clear inter-row gap above the box instead, dropping into the target from the clear inter-column channel (issue #1428).
