Same Side Culdesac

Gallery / Inter-section Routing

A line declares its entry on a reversed (RL) section's flow-trailing edge, the edge the section flows out of, but its consumer is an interior station held off the leading end by a file terminus. Rather than fold the line back over the trunk to reach it, the entry re-anchors to the section's leading edge; the producer then reaches it by wrapping over the section top, so the line reads as a clean loop and the consumer is a straight pass-through.
