Abstract: Bridge structure, but subjects all approaches to a signal (no "freeway" movements). Functions similar to Town Center Intersection (intersecting couplets), but does so vertically rather than laterally. Good choice when seeking to avoid freeway precedent, and both streets have similarly high volumes. Won an AASHTO award for innovative design somewhere around 2002.
Abstract: The whole area has streets for both autos and boats! This is fairly common in Florida, and this is just one example.
