This view of the Eastern State Parkway near Fishkill, New York, typifies approximately the kind of construction proposed for rural sections carrying upwards of 3,000 vehicles a day. Note that the opposing traffic lanes are constructed as practically separate roadways on different grades, each fitted to the topography with resulting reduction of cost. Such sections of the system may be built at costs of from $100,000 to $150,000 per mile, depending largely upon the costs of right-of-way and grade-separating structures.
All rural sections of the system carrying traffic of 10,000 or more vehicles daily are located within zones of traffic influence of cities. The above view of Northern State Parkway at Westbury, Long Island, is fairly representative of the type of construction proposed. Costs may range from $150.000 to $700,000 per mile, depending largely upon right-of-way expense.
