[9] The original roadway was an undivided freeway, designed with gently sloping curves, stone arch bridges, and wooden lightposts.
[2] In 1930, Robert Moses, an American public official who worked on New York metropolitan area infrastructure, announced plans to build more parkways in the Bronx.
[22][23][24] Modifications in 1984 included the straightening of some curves, increased sight distances, removal of the rustic lightposts, and lengthening of acceleration and deceleration lanes.
