This is what Manhattan would look like if everyone had to drive to work:
According to Vancouver highway engineer Matt Taylor, the island would need 48 new bridges that would each have to carry eight lanes of traffic … Taylor arrived at that number by noting that 2,060,000 people commute to Manhattan daily. Under ideal conditions, a single lane can convey about 2,000 vehicles per hour, so to let 2.06 million cars on to the island within a four-hour period, you’d need at least 380 additional bridge lanes — or roughly 48 new eight-lane bridges. Of course, you’d also need somewhere to put all those extra cars. Taylor calculates that they’d require about 24 square miles in total, which is exactly the land area of Manhattan. In other words, you’d need to build a layer of underground parking that takes up the entire borough to fit all the cars driven in by commuters.
