Left Exit Sink Below

Gallery / Inter-section Routing

A TB bridge's LEFT exit feeds a LEFT-entry sink one row below and to the left: the bundle leads out left and drops straight down a channel clear of both boxes, routing around the bridge rather than clawing back through its interior (issue #1083).
