Some of the earliest American cul-de-sac communities were built in Radburn, N.J., in the 1920s. By the mid-1950s, they were everywhere. Developers learned that cul-de-sacs allowed them to fit more houses into oddly shaped tracts, and to build right up to the edges of rivers and property lines.

"Going over the lines had two problems," Lucy says. "One, it was expensive to try to traverse the obstacles. Second, it made connection to other neighborhoods or other subdivisions, and that was contrary to the notion of safety."

Does it mean "remove"? I am not sure.
