"When you operate in an overbuilt metropolis, you have to hack you way with a meat ax." Those were the words famed urban planner Robert Moses used to describe the need for a thick highway running the span of lower Manhattan, one that had been in the planning stages since the 1920s. The Lower Manhattan Expressway was meant to speed traffic across the island, part of Moses' ideal that cities should be redesigned in service of cars. The opposition, which Moses called "nothing...but a bunch of mothers," was led by activist Jane Jacobs, who questioned the wisdom of destroying inner city neighborhoods. The "Lomex" would have eaten housing for 2,000 families, 800 business and destroyed much of what's known as SoHo today. After approving the road in 1964, officials fell into a debate that eventually led to the project's cancellation in 1971 -- although many other cities went ahead with Moses-like plans.
