This view of a section of the Henry Hudson Parkway in New York is representative of the type of depressed expressway proposed for construction through the residential sections of cities. The cost may be expected to vary from $700,000 to $1,250,000 per mile depending upon property acquisition costs.
The Gowanus Elevated Parkway in New York, typical of elevated construction that may be employed near the centers of larger cities, cost $3,000,000 per mile. A large part of the cost was made up of the right-of-way expense engendered by widening of the street in which it was built. Even though attractively designed, elevated roadways are aesthetically undesirable in the midst of some parts of cities, such as residential areas. They also tend to divide a community and to act as barriers, at least psychologically, between the divided sections. This particular elevated structure in New York is appropriately located, however, because it divided a residential community (on the left) from an industrial and dock area.
