New York runs on the connective nature of the city. A web of trains, subways, buses, and sidewalks creates a city where a car is a luxury and not a necessity. The majority of the city is walkable, creating the pedestrian atmosphere of New York. A few locations throughout the city break this web and create an area that lacks connectivity. A dead zone. The rotary exiting the Holland tunnel takes up 16 acres and forces pedestrians to rout around the multi-block area.
Visualizing the impact of the rotary and the amount of cars that pass through it in a day allows one to see just how large of an impact the cars have on the rest of the city. The area is inaccessible and not crossable. This is the reason for the dead zone of activity around it. By allowing people to flow freely over the rotary it would allows for a continuation for the flow of pedestrians through that area of Manhattan.
